Description

  The present invention relates to a system for applying energy to human tissue, and in particular to such a system for treating a lumen such as a vein. The present invention also relates to a medical device including an energy supply device capable of measuring the temperature of a treatment site and controlling the amount of energy supplied when treating such a lumen portion, and a method of using the medical device.

  Currently, doctors use an intravascular method that supplies laser energy by conduction when treating blood vessels such as varicose veins. Such a method is described in Patent Document 1. This patent document discloses a method for treating varicose veins using a pointed laser energy carrier to supply laser energy into the lumen of the blood vessel and subsequently create an injury in the venous wall that subsequently becomes fibrotic. . In this method, while supplying a burst of laser energy, the large saphenous vein is pressed against the distal end of the optical fiber so that the distal end of the optical fiber is in direct contact with the vein wall, and the optical fiber is gradually moved along the large saphenous vein. Pull back to.

  When treating varicose veins using a device that supplies energy by conduction, it is desirable to accurately control the temperature reached by human tissue in order to effectively treat it. One problem with using such a general fiberization method to provide energy to the vein or lumen wall is that the optical fiber is substantially uniform with respect to the lumen wall. If the energy cannot be supplied evenly and radially, the contraction and fibrosis of the vein wall will not be uniform. Unequal energy supply has detrimental consequences. The use of diffusing optical fibers helps to avoid uneven energy supply.

  In the treatment of damaged spinal discs, physicians have used diffuse energy delivery devices where the annulus caused by the injury can be reduced by heating the annulus and causing the collagen to contract. Patent Document 2 discloses a method for treating such an intervertebral disc. The method includes inserting a light source into a damaged disc, activating the light source to emit diffuse light, optically measuring the temperature of tissue near the light source, and according to the measured temperature. Altering the intensity of the emitted light. Some fiber optic devices are useful for heating the disc annulus in a controlled manner, but there are anatomical differences between incremental treatments along the length of the lumen, such as varicose veins, and disc treatments. The desired therapeutic effect is clearly different. In treating varicose veins, as the entire length of the varicose vein is treated, the amount of energy absorbed by the varicose vein can be monitored by measuring the temperature along each incremental portion of the varicose vein. Even small variations in treatment from one part to another can affect the overall therapeutic effect.

  In medical procedures where the optical fiber moves incrementally within the varicose veins, under-exposure of a treatment site with varicose veins or over-exposure of another treatment site can have deleterious consequences. By accurately measuring the tissue temperature at each treatment site, an appropriate level or intensity of treatment can be ensured along the length of the entire treatment site. Specifically, tissue temperature discrepancies or fluctuations along a particular portion of the varicose vein being treated or along its length suggests undesirable variability in the energy supply, such variability being over-treated or under-treated in the tissue. It becomes a treatment and results in undesired clinical consequences, including failure of varicose fibrosis, and requires further surgical procedures.

By using diffusion instead of conduction for energy supply, energy can be supplied more evenly along the varicose veins. Accordingly, it is desirable to utilize a diffusion fiber optic device that can automatically control the amount of energy delivered to each treatment portion and monitor and control the temperature along each treatment portion of the varicose vein and along its entire length.

The light emitting portion of the optical fiber can be moved incrementally or continuously. The light emitted from the visible wavelength marker laser can be visually confirmed to align the light emitting portion with the treatment site. The optical fiber can include a temperature sensor for optically measuring the temperature in the human tissue of the treatment portion. The energy supply device may include a memory element having stored parameters. The main processor can compare the optically measured temperature with at least one parameter stored in the memory element. The main processor can automatically control the placement of the light emitting portion within the treatment site and automatically adjust the energy delivered from the energy generator to the light emitting portion according to the measured temperature You can also.

  In one embodiment, the present invention provides a method for hyperthermizing a lumen using a medical device including an energy generator and an energy delivery device having an optical fiber. The energy supply device may include a memory element, and the energy generator may include a main processor. The method includes a plurality of steps. First, an optical fiber is inserted into the lumen of a treatment site having at least two treatment portions. The light emitting portion of the optical fiber is aligned with the first treatment portion within the treatment site. Energy is released into the lumen of the first treatment portion and the temperature of the lumen of the first treatment portion is measured. The energy delivered to the treatment part is adjusted according to its temperature measurement. The light emitting portion is moved to at least a second treatment portion within the lumen and releases energy into the lumen of the second treatment portion. During treatment of the second treatment portion, the temperature of the lumen of the second treatment portion is measured.

The method includes storing a target temperature in a memory element, generating a temperature signal using a temperature sensor, determining a measured temperature using the temperature signal, and storing the measured temperature in a memory element. Comparing to the target temperature determined. If the measured temperature is equal to or above the target temperature, the light emitting portion is moved to the next treatment portion.

It can be coupled to the device 12. The energy supply device 12 can be any energy supply means or any device capable of supplying various types of useful energy from the energy generator 22.

  The energy supply device 12 can be connected to the connector housing 36 by inserting the connector 28 into the opening 42 of the connector housing 36 and fixing the connector 28 at a predetermined position. The connector 28 is inserted into the connector housing 36 and then pivoted about the longitudinal axis 78 to be secured to the connector housing 36. In one embodiment, the energy supply device 12 is a disposable supply with a limited expiration date that includes data stored therein in the form of usage parameters and characteristics for supplying energy from the energy generator 22 to human tissue. It can be a device. In this embodiment, the energy supply device 12 can be rotated about the longitudinal axis 78 in a direction opposite to the fixed direction to release the connector 28 from the connector housing 36 and remove it from the energy generator 22. .

  The alignment device 70 is operatively connected to the energy generator 22 by a wire harness 47. The wire harness 47 can be connected to the receptacle 43 by inserting the insertion pin 49 of the plug 45 into the receptacle 43.

  As shown in FIG. 1, the energy generator 22 may include a keypad 92 on the cover 17 so that data can be entered as a user interface. The energy generator 22 may also include a display screen 94 on the cover 17 for displaying data, warnings, or other information. The alignment device 70 can also include a remote or touch screen 74 on the panel 77 to display data, warnings, or other information from the remote energy generator 22. Therefore, the doctor can read such information without leaving the patient being treated.

  FIG. 2 shows the energy generator 22 with the cover 17 removed and the inside of the energy generator 22 exposed. In this embodiment, the connector housing 36 and the receptacle 43 are electrically connected to the control panel 57 on the energy generator 22 by the conductive wire 52. A computer in the form of a main processor 25 is arranged on the control board 57. The main processor 25 receives and processes electrical signals and controls the operation of the medical device 10. The main processor 25 can be, for example, a microprocessor or a small computer. Signals from the electronic components in the energy supply device 12 and the alignment device 70 are transmitted to the control panel 57 and the main processor 25 via the lead wires 52. Alternatively, separate conductors 52, control board 57, and main processor 25 can be used for each component. Further, the main processor 25 can be functionally connected to the keypad 92 and the display screen 94.

  In operation, main processor 25 directs the energy supply process in accordance with user instructions or programmed instructions via keypad 92 and data from energy supply device 12 and alignment device 70, as will be described in detail below. . The main processor 25 sends information about the energy supply process to the screen display 94 and / or the remote screen 74 for review by the user. The main processor 25 can also stream information in a manner known in the art. If the user finds information about an undesirable process, such as not safe for the patient being treated, the user can override the operating command via the keypad 92.

  As shown in FIG. 3, the connector 28 includes a handle portion 88 shaped to be easily gripped by the user. The handle portion 88 has a boot 64 attached to its distal end. The optical fiber 13 extends from the boot 64 to the tip side. A barrel 86 extends from the proximal end of the handle portion 88. A connector face 56 separates the barrel 86 from the handle portion 88. A flange 82 extending radially from the longitudinal axis 78 is attached to the barrel 86. The flange 82 has a contact pad access opening 46 disposed on its large side. An axial gap 80 exists between the tip of the flange 82 and the connector face 56. A ferrule 16 is disposed in the connector 28. A part of the ferrule 16 extends from the base end of the barrel 86. The ferrule 16 is a form of energy transmission attachment for transmitting energy from the energy generator 22 to the energy supply device 12 for treatment. The barrel 86 of the connector 28 can be inserted into the opening 42 of the connector housing 36 to functionally connect the energy supply device 12 to the energy generator 22.

  FIG. 4 is a cross-sectional view of the connector 28 showing the inside of the connector 28. The ferrule 16 includes a passage 60 that passes through the center thereof. The light energy generated by the energy generator 22 can be introduced into the optical fiber 13 through the passage 60. The passage 60 of the ferrule 16 is coaxial with the longitudinal axis 78. An inner surface of the handle portion 88 engages the enlarged portion 18 of the ferrule 16 and a boot 64 holds the optical fiber 24 extending from the handle portion 88 of the connector 28. A printed circuit board 66 in the flange 82 is illustrated to show the mating surface 97. The printed circuit board 66 can be embedded in the flange 82 such that only the contact pads 59 are exposed to the outside through the access opening 46. The connector 28 is preferably a molded product of a non-conductive material such as plastic.

  FIG. 5 shows a surface of the printed circuit board 66 opposite to the surface of the printed circuit board 66 shown in FIG. At least one memory element 58 is disposed on the surface of the printed circuit board 66 opposite to the mating surface 97 and is electrically connected to the contact pad 59. The memory element 58 can be, for example, a programmable read only memory element (EEPROM) that can be electronically erased, and can store information useful for the operation of the energy delivery device 12 and the medical device 10.

  When the connector 28 is in a fixed position, the memory element 58 can communicate electronically with the main processor 25 of the control board 57 by way of the contact pads 59 and the conductors 52. Information in the memory element 58 can be accessed by the main processor 25 and vice versa.

  Although the memory element 58 is described as an EEPROM capable of storing a large amount of data, the memory element 58 may be any non-volatile memory such as various digital storage devices, optical storage devices, or magnetic storage devices, or an integrated circuit having a memory function. It can also be. For example, such a memory device 58 includes a read only memory (ROM), a programmable read only memory (PROM), a programmable read only memory (EPROM) that can be erased, a flash memory, a non-volatile random access memory (RAM), Or most preferably an EEPROM. Of course, various types of memory elements 58 can be used in accordance with the present invention, so that all data sets and information need not be stored in one memory element 58 or a single type of memory element 58. Further, although it has been described that the memory element 58 is mounted on the printed circuit board 66 embedded in the flange 82, the printed circuit board 66 or the memory element 58 may alternatively be mounted externally or separately. It should be understood that it may be a completely separate assembly or device that is functionally connected to the energy generator 22 or the energy supply device 12 by any electrical connection or other connection method. Furthermore, the memory element 58 can be operatively connected to the optical fiber 13 from a location remote from the energy supply device 12 without departing from the scope of the present invention. As used herein, the term “functionally connected” refers to the ability of components to exchange data or transmit energy between components, such as through electronic data communication between components. Furthermore, while it has been described that data exchange between the memory element 58 and the energy generator 22 can be accomplished by electronic means, it can also be accomplished by magnetic means, infrared means, radio frequency means, or optical means. These alternative methods and other methods that can be easily conceived by those skilled in the art without undue experimentation are also within the scope of the present invention.

  The energy supply device 12 used for such a purpose usually includes from the connector 28 to at least the tip of the optical fiber 13. Preferably, the energy supply device 12 includes means for releasing energy towards human tissue at or near its tip. Specifically, the medical device 10 including the energy supply device 12 is used for irradiating a human tissue with laser light energy, for example, when treating a human tissue with a thermotherapy or the like in a blood vessel or other lumen. it can. The term “lumen” as used herein refers to a hole or cavity in a tubular organ.

  Refer now to FIG. As shown, the energy supply device 12 according to one embodiment of the present invention includes a diffuser or light emitting portion 19 at the distal end and a non-diffusing portion or light transmitting portion 34 extending toward the proximal end. . In the optical transmission portion 34 of the optical fiber 13, the base end portion of the clad 32 and the sheath, that is, the sleeve 38 covers the base end portion 30 of the core 31 in the radial direction. The optical fiber 13 may include a jacket or buffer layer 41 disposed so as to extend circumferentially between the cladding 32 and the sleeve 38. The refractive index of the material used to form the clad 32 is lower than the refractive index of the material used to form the glass or core 31 so that light is confined in the core 31 over the entire length of the light transmission portion 34. In the light emitting portion 19 of the optical fiber 13, the core 31 extends beyond the proximal end portion 30 to the distal end portion 39 through the distal end portion 33. The distal end portion 33 of the core 31 used for diffusing light is covered with the optical coupling layer 40, so that the distal end portion 44 of the sleeve 38 defines the light emitting portion 19 that does not include the cladding 32 of the optical transmission portion 34. There is no. Arrows 98 illustrate the diffused light energy that is evenly emitted radially from the light emitting portion 19 in the radial direction.

  The optical coupling layer 40 is formed of a material having a refractive index higher than that of the core 31. Preferably, the optical coupling layer 40 is formed using a UV50 adhesive sold by Chemence, founded in Alpharetta, Georgia. Other adhesives that can be used include XE5844 Silicone sold by General Electric Company and 144-M sold by Dymax located in Torrington, Connecticut. Can do.

  The sleeve 38 can extend to the distal end side beyond the distal end portion 39 of the core 31 to constitute the distal end portion 50. In one embodiment, the tip 50 can be formed into a pointed tip that can be inserted into human tissue so that certain medical procedures can be performed. In another embodiment, the tip 50 is another such as a round, spherical, or non-pointed tip that can be used to treat varicose veins in which the optical fiber 13 is introduced into human tissue via a cannula. It can be in form and structure. In a preferred embodiment, the sleeve 38 of the optical fiber 13 is a continuous piece, more preferably the sleeve 38 comprises perfluoroalkoxy containing barium sulfate.

  A light scattering element 48 filled with a light scattering material is disposed at the tip 39 of the core 31 and can reflect light back into the core 31 so that light is emitted more evenly or uniformly. . In a preferred embodiment, alexandrite is used as the light scattering material for the light scattering element 48. In addition to this light scattering property, the light scattering element 48 fluoresces depending on its temperature when stimulated by light. For example, the absorption of some light energy stimulates the light scattering element 48, which causes the light scattering element 48 to generate light energy in the form of a temperature signal with a long wavelength and a phase or time delay, based on this light. Return to the core 31 toward the end. The frequency or time delay between the light energy absorbed by the light scattering element 48 and the light energy emitted by the light scattering element 48 depends on the temperature of the light scattering element 48. The main processor 25 calculates the temperature using this phase shift, that is, the temperature signal, and converts it into a temperature measurement value. This temperature-dependent fluorescence characteristic of the light scattering element 48 is used as the temperature sensor 99. Thus, the fluorescent properties of alexandrite particles when stimulated by light energy of the appropriate wavelength can determine the temperature of the human tissue around the light emitting portion 19 by methods well known in the art. In this closed loop method, the temperature index of human tissue at the treatment site in the vicinity of the light emitting portion 19 or the tip 50 is measured optically.

  Various data and information can be converted to digital form and loaded, stored, or programmed into the memory element 58. Methods for storing this data and information in digital form are well known in the art. Use or establish parameters associated with this particular data and information. As used herein, the term “parameter” is used as a symbol for variables, functions, constants, and parametric equations.

  In one example, usage related parameters can be preset during manufacture or set during use, static (having a fixed value) or dynamic (variable or variable) associated with the medical device 10. Can contain or be derived from the following data and information that have values: Such data and information includes supply means identification, supply means expiration or no expiration date, calibration parameters, scale and offset factors, self-heating characteristics, energy supply types, operating parameters, energy supply parameters, Monitoring sequence parameters, identification of generator means, energy supply, maximum power, power range, power transmission, wavelength, data integrity factor, time since first recognition of energy source, identification number, lot number, expiration date, Past usage records, energy delivery time, energy delivery rate, insertion rate or pullback rate, total joules delivered, number of treatment sites, treatment site dimensional characteristics (length, diameter, thickness, etc.), treatment identification, type , Date or time, total treatment time, treatment organ, treatment time in each part, treatment type, treatment Human tissue characteristics, mode of operation, elapsed time, total elapsed time of all treatments, treatment part temperature level, target temperature, maximum temperature, identification of multiple generator means, achievement of a constant temperature level or power level Record data, record data for use by multiple generator means, display or identify errors or warnings, or abnormal or intermediate termination of all treatments, including problematic conditions that occurred during all treatments, and these Any combination or partial combination of is included. Parameters associated with such use may also include various other data and information about the operation of the optical fiber 13, energy supply device 12, alignment device 70, energy generator 22, or medical device 10.

  The main processor 25 can automatically change the intensity or energy output of the energy generator 22 using data and information stored in the memory element 58. In addition, the main processor 25 can determine the information contained in the memory element 58. For example, when applying power to operate the alignment device 70 or the energy supply device 12, the main processor 25 may receive certain data and information communicated between the main processor 25, the memory element 58, and the alignment device 70. , The energy supplied by the energy generator 22 can be reduced, increased, disabled or stopped. As a further example, the main processor 25 creates a message containing an error message about the data, and the display screen 94 of the energy generator 22 is displayed on the remote screen 74, or the alignment device 70, or notified by voice. it can. The main processor 25 can even write information to the memory element 58 for storage in the memory element 58 using the energy supply device 12.

  Preferably, the energy supply device 12 with connector 28 is an Indigo® Optima laser system sold by Ethicon Endo-Surgery Inc., Cincinnati, Ohio. ) Coupled to the optical fiber system. The energy supply device 12 and the energy generator 22 are described in US Pat. No. 6,503,269 (named “Light Energy and Optical”, assigned to the assignee of the present invention by Nield et al.

  FIG. 7 shows the alignment device 70 with the panel 77 removed and the interior exposed. In the illustrated embodiment, remote processor 73 is electrically connected to energy generator 22 and other components of medical device 10 by wire harness 47. A first motor 71 and a second motor 72 are functionally connected to the remote processor 73. Therefore, the remote processor 73 can receive and process the electrical signal from the main processor 25 and control the operations of the first motor 71 and the second motor 72 of the alignment device 70. The first motor 71 can be directly connected to the first roller 75 via the first driving device 83. Similarly, the second motor 72 can be directly coupled to the second roller 76 via the second drive device 84. The first roller 75 and the second roller 76 are preferably spaced apart from each other and are disposed close to each other and are formed from a rubber material. During operation, the first motor 71 and the second motor 72 convert electrical energy into mechanical energy, and the first driving device and the second driving device are respectively in the opposite direction to the first roller 75 and the second driving device. Each of the two rollers 76 is rotated. The space between the first roller 75 and the second roller 76 allows the optical fiber 13 to pass between these rollers while being in contact with the respective rollers. In other words, the first roller 75 and the second roller 76 are engaged with the optical fiber 13 to control the movement of the optical fiber 33 sandwiched between these rollers. As illustrated, the optical fiber 13 engages a first roller 75 that rotates in a substantially counter-clockwise direction and a second roller 76 that rotates in a substantially clockwise direction. Therefore, it can move in the tip direction. When the first roller 75 and the second roller 76 rotate in the reverse direction, the optical fiber 13 moves in the proximal direction. The first motor 71 and the second motor 72 are synchronized so that the first roller 75 rotates in the opposite direction to the second roller 76. The rotation of the first roller 75 and the second roller 76 is preferably smooth over the entire movement range. More preferably, the rotational speeds of the first roller 75 and the second roller 76 can be varied over a wide range and can be stopped for increments at any time point during the rotation. In this manner, the alignment device 70 can move the light emitting portion 19 of the optical fiber 13 continuously or incrementally in either the distal or proximal direction.

  Once the energy supply device 12 is connected to each of the alignment device 70 and the energy generator 22, the energy supply device 12 receives energy from the energy generator 22 and energy from the light emitting portion 19 of the optical fiber 13 to human tissue in accordance with the present invention. Can be supplied.

  In an alternative embodiment, the alignment device 70 can have a wire harness 47 that is directly connected to a regular electrical outlet. In this embodiment, a physician manually enters commands into alignment device 70 using a remote screen or touch screen 74 or other commands known in the art for entering commands to operate alignment device 70. The method can be used to guide the light emitting portion 19 of the optical fiber 13 within the vein 91. In response to such a command, the remote processor 73 can control the rotation of the first roller 75 and the second roller 76 to appropriately arrange the light emitting portion 19 as described above.

  Refer now to FIG. An energy generator 22 is connected to the energy supply device 12 and the alignment device 70. The energy supply device 12 includes an optical fiber 13 having a temperature sensor 99 and a light emitting portion 19 disposed at the tip. The temperature sensor 99 generates a temperature signal by the above-described closed loop method. The optical fiber 13 engages the first roller 75 and the second roller 76 of the alignment device 70 as it enters the housing 81 through the opening 20 and exits the opening 21. The optical fiber 13 can be inserted directly into the vein 91 and placed appropriately in the varicose portion 93 of the vein 91 of the patient's human tissue or leg 90 as determined by the physician. The alignment device 70 is preferably attached to the patient's leg 90 using a support strap 79. Alternatively, the alignment device 70 can be held by a support frame instead of the support strap 79 and can stand independently in close proximity to the patient and the leg 90.

  In this embodiment of the invention, the medical device 10 includes an energy generator 22, an alignment device 70, and an energy supply device 12. The energy generator 22 and the alignment device 70 are functionally connected by the wire harness 47. The main processor 25 in the energy generator 22 is used to control the operation of the medical device 10 including the placement and relocation of the light emitting portion 19 of the optical fiber 13 within the vein 91 of the leg 90 by the alignment device 70. In this configuration, the medical device 10 can emit laser light energy for treatment of the vein 91.

  During normal operation of the medical device 10, light energy of different wavelengths is generated by the energy generator 22 in the form of a treatment laser and a marker laser. This light energy travels through the core 31 to the light emitting portion 19. Since the optical coupling layer 40 has a higher refractive index than the core 31, this light energy is emitted from the core 31 to the optical coupling layer at the light emitting portion 19. The tip portion 44 of the sleeve 38 covering the optical coupling layer 40 preferably diffuses light energy radially toward human tissue by the barium sulfate particles dispersed within the sleeve 38. The light emitting portion 19 is used to scatter and diffuse this light energy to the treatment site to heat the treatment site. The treatment laser is light energy having a wavelength in the range of about 810 nm to about 830 nm and is used to treat the vein 90 with hyperthermia. The marker laser is light energy having a wavelength of about 635 nm in the visible spectrum and is used to stimulate the temperature sensor 99. The pulsed light energy that reaches the light scattering element 48 is absorbed and then released again by the alexandrite particles in the light scattering element 48 to return toward the core 31. The marker light energy has a wavelength different from that of the marker laser and is delayed in transfer with respect to the marker laser. Since this marker laser light energy can be seen through human tissue, the doctor can use this marker laser light energy to identify the position of the light emitting portion 19. Specifically, the optical fiber 13 can have an alignment visible mark on its sleeve 38. The doctor can check the position of the light emitting portion 19 and the degree of the optical fiber 13 inserted into the patient's leg 90 by using such an alignment mark.

FIG. 9 illustrates the optical fiber 13 located in the varicose vein portion 93 of the vein 91 and the light emitting portion 19 thereof. Multiple adjacent treatment portions are shown as lengths D _a -D _z . As shown, the treatment portion D _m is treated with light energy (arrow 98) emitted radially from the light emitting portion 19. The entire varicose portion 93 of the vein 91 can be the treatment site illustrated as length L. Each of the treatment portions D _a -D _z is _a part of the entire treatment site L. In other words, the treatment site L includes treatment portions D _a -D _z . The plurality of treatment portions D _a -D _z can be treated incrementally with laser light energy 98. When the thermal treatment of the treatment portion D _m is completed, the alignment device 70 causes the optical fiber 13 to be incremented along its length to the next adjacent treatment portion D ₁ within the entire length L of the treatment site or It can be moved and rearranged in a continuous manner. Delivering energy to the energy supply device 12 incrementally corresponding by the energy generator 22 can be treated by supplying the laser beam energy 98 to a new treatment portion D _1. This process can be repeated until the entire treatment site L of the vein 91 has been treated with the laser light energy 98.

  In a preferred embodiment, the data stored in the memory element 58 can be directly related to the length, thermal energy, and treatment temperature for a particular treatment site L. Thus, the memory element can send information to the main processor. The main processor 25 guides the movement of the optical fiber 13 and adjusts the intensity of the laser light energy emitted by the light emitting portion 19 toward each particular treatment portion D within the treatment site L. Once an expected or target temperature is detected at treatment site D, main processor 25 can advance or retract optical fiber 13 with alignment device 70 to align light emitting portion 19 with the next adjacent treatment portion D. . Alternatively, the information and data programmed into the memory element 58 can be scaled to the dimensional characteristics of the varicose portion 93 of the vein 91 so that the thermal treatment of the vein 91 corresponding to incremental pullback of the optical fiber 13 is automatically performed. Can be related. In this manner, the optical fiber 13 can be pulled back at a constant rate or substantially continuously at which the treatment temperature can be reached at a particular treatment portion D. The optical fiber 13 can also treat each treatment portion D and retract it incrementally before being automatically pulled back to the next incremental treatment portion D along the length L. Because the characteristics for the varicose portion 93 of the vein 91 and any particular characteristics of the patient's leg 90 can all be programmed into the memory element 58 along with a number of other treatment parameters including suitable temperature and pullback rate, the optical fiber The medical device 10 can be programmed to automatically treat the patient in incremental fashion as 13 is pulled back or moved along the varicose portion 93 of the vein 91. Preferably, the alignment device 70 moves or pulls back the light emitting portion 19 at a moving speed that can adequately supply the light energy 98 into the respective treatment portion D. This movement of the light emitting portion 19 can be a schedule preset with data stored in the memory element 58, more preferably a moving speed in the range of about 2.54 cm / min to about 25.4 cm / min. .

  Refer now to FIG. One skilled in the art will appreciate that the data and information described above can be stored in the memory device 58 in a variety of ways well known to those skilled in the art (205). In this embodiment of the invention, it is preferred to functionally connect the energy supply device 12 and the alignment device 70 to the energy generator 22 by direct electrical connection (210). When connected to the memory element 58 of the energy supply device 12, the main processor 25 of the energy generator 22 and the remote processor 73 of the alignment device 70 read data and information from the memory element 58, and data and information to the memory element 58. Can be written (215). The physician can also program or enter patient specific data. For example, the physician can store the length of the treatment site L of the vein 91 to be treated, including the specific length of the desired treatment portion D, and program the medical device 10 or memory element 58. Any error message or other support message can be checked 220 on the display screen 94 and remote screen 74. If an error message is displayed, the physician can stop treatment and resume treatment after all such errors or problems are resolved (225).

The physician can check the marker laser light after operating the medical device 10 and inserting it into the lumen tissue (230). The optical fiber 13 and the light emitting portion 19 can be placed in a suitable treatment portion D of the treatment site L (240). The treatment can then begin. The physician initiates the treatment so that the main processor 25 activates the energy generator 22 so that the appropriate intensity of energy is emitted from the light emitting portion 19 (245). In operation, the temperature sensor 99 can send a temperature signal that matches the measured temperature of the treatment portion D back to the main processor 25 (250). Parameters other than temperature can be checked and measured if appropriate. Next, the target temperature stored in the memory element 58 is compared with the measured temperature (255). Target temperature can be varied from the treatment portion D _a in the target site L at therapeutic moiety D _z. If the target temperature is not reached, the main processor 25 can increase the energy output by the light emitting portion 19 or adjust the moving speed of the light emitting portion 19 in response to the measured temperature (260). This treatment can continue in this manner until the particular parameter being measured is equal to the target parameter (265).

  Main processor 25 may adjust (270) the position of optical fiber 13 to move light emitting portion 19 to the next treatment portion D within the lumen. Specifically, the main processor 25 communicates with the remote processor 73, operates the alignment device 70, engages the first motor 71 and the second motor 72 with the optical fiber 13, and treats the treatment in the vein 91. A predetermined distance based on the length of the portion D can be moved. This length can be initially programmed into the medical device 10 by the physician or stored in the memory element 58. The medical device 10 releases and treats light energy toward the specific treatment portion D at the intensity determined by the main processor 25, and automatically performs this process until the entire length of the treatment site L of the vein 91 is treated. It can be repeated (275).

  Alternatively, the physician can program the memory element 58 and the medical device 10 for the entire length of the treatment site L of the vein 91 to set the target temperature and then begin treatment as described above. An energy generator 22 transmits light energy through the optical fiber 13 and emits light energy 98 into the varicose portion 93 of the vein 91 through the light emitting portion 19 and is measured by the temperature sensor 99 in the treatment portion D. Until the temperature reaches a predetermined target temperature. The temperature of the treatment portion D is determined using the temperature sensor 99 in the above-described closed loop system. The main processor 25 can activate the alignment device 70 to continuously pull back or move the optical fiber 13 through the vein 91. To maintain the desired target temperature at each target portion D, the main processor 25 controls the speed and / or energy level and power intensity at which the optical fiber 13 is pulled back based on the data stored in the memory element 58. The pullback speed and the intensity of the emitted energy can be adjusted automatically and continuously over the entire length of the treatment site L of the vein 91. In this manner, the medical device 10 can most effectively treat the vein 91 over all treatment cycles. Alternatively, the pullback of the optical fiber 13 from the vein 91 can be in small incremental steps or positions as indicated by the treatment portion D, and the movement between incremental steps can be constant or variable speed. Can do. The light emitting portion 19 can also have a predetermined stop time between each incremental step.

  In an alternative embodiment of the present invention, the medical device 10 can be operated without the alignment device 70. The physician can simply place, move, and retract the optical fiber 13 with respect to the vein 91 using the marker laser light and position mark to properly place the light emitting portion 19. The physician can grasp and push or pull the optical fiber 13 to place or align the light emitting portion 19 with the varicose vein portion 93 of the vein 91. When the treatment is started, the doctor sends the temperature measurement value from the temperature sensor 99 displayed on the remote screen 74 or the display screen 94 to the light emission portion 19 along the length of the vein 91 in a treatment portion L in the treatment site L. The optical fiber 13 can be manually pulled back as a visible clue to the speed at which it is moved from D to another treatment portion D.

  Once energy is supplied to the human tissue and the medical procedure is terminated, the therapy can be terminated (280). Data related to the medical procedure or all information useful to the medical device 10 can be updated to the memory element 58 (285). The optical fiber 13 is removed from the lumen and the medical device 10 is stopped. The user can remove the plug 45 from the receptacle 43 and remove the connector 28 from the connector housing 36 for easy storage. The plug 45 can be simply removed from the receptacle 43 by pulling, but when the connector 28 is removed, the user must rotate the connector 28 from a fixed position to a fixed release position. After rotating the connector 28 to the unlocked position, the user can easily remove the connector 28 from the energy generator 22 by pulling on the handle portion 88.
