VARIABLE VOLUME PROSTHETIC ASSEMBLY RELATED APPLICATION This application is a continuation-in-part of my copending application entitled Variable Volume Prosthetic Assembly", U.S. Ser. No. 28l,l50, filed Aug. I6, 1972, and now abandoned.
BACKGROUND OF THE INVENTION Implantable prostheses of the type shown in U.S. Pat. No. 3,665,520, entitled Surgically Implantable Breast Prosthesis are prefilled to the desired shape with a silicone gel. In order to implant a prosthesis in the body, it is necessary to make an incision of a length sufficient to insert the prefilled prosthesis through the incision into the body. Once implanted, the volume of this prosthesis could not be changed without removing the prosthesis. Empty flexible containers have been implanted in the body and subsequently filled by injecting liquids or a gel into the container. However, difficulties have been encountered in inserting silicone gels into the containers having the required viscosity. The equipment required to fill this type of implant is also more complicated, increasing thedifficulty in maintaining operating room standards.
SUMMARY OF THE INVENTION The variable volume prosthetic assembly of the present invention overcomes the above problems by using a closed system which includes a reservoir for storing the gel attached to an empty container. The silicone gel is thus sealed into the closed system at the point of manufacture. The entire system can be shipped ready for use and autoclaved at the point of manufacture. The flexible container for the prosthesis can be implanted empty in a rolled up or flattened condition and therefore can be inserted into a much smaller incision.
Once the empty prosthesis has been implanted, it is a simple step to squeeze the reservoir to force the silicone gel from the second container into the prosthesis. The second container is connected to the first container by a tube which is secured and sealed to the two flexible containers. Once the first or implanted container has been filled to the desired fullness, the tube can be tied and cut, folded over and tied, and then sutured to the back of the flexible container. This closed system eliminates the necessity of using additional equipment to insert the gel into the prosthesis after implanting and as a consequence simplifies the entire operation. The tube can also be provided with a valve or plug for automatically sealing the container and reservoir during storage and after implanting the container in the body.

DESCRIPTION OF THE INVENTION The implantable prosthetic assembly 10 of the present invention as seen in FIG. 1 includes a first flexible container or shell 12 and a second flexible container or reservoir 14. The containers 12 and 14 are connected by means of a tube 16 which is formed as an integral part of the two containers l2 and 14. The second eontainer 14 is filled with a silicone gel 18 and the entire assembly autoclaved at the time of manufacture. The silicone gel 18 is transferred to the implanted shell 12 by squeezing the reservoir 14 to force the silicone gel 18 into the shell 12.
The first container or shell 12 is formed from an implantable material such as an organopolysiloxane compound as set forth in U.S. Pat. No. 3,665,520 or from a silicone rubber such as General Electric Elastomeric Resin 7000. The G. E. Elastomer resin contains R Si- 0 groups, and small amounts of vinyl R SiO, where R represents methyl groups. This elastomer is known to have characteristics such as softness and resiliency'that can be controlled to approximate that of the human body. The container 12 can be made to approximate any shape and as shown is formed with a front surface 11 having the general shape of a natural breast and a back surface 22 which is shapedto follow the general contour of the chest wall.
The second container or reservoir 14 can be formed from the same material as the first container 12 or from a medical grade material such as silicone polycarbonate copolymer. The reservoir 14 preferably has a volume equal to or greater than the volume of the first container 12. If desired, graduations 24 can be provided on the surface of the reservoir 14 to indicate the amount of silicone gel 18 available to be forced into the prosthesis 12.
The second container 14 is filled with the silicone gel 18 such as set forth in US. Pat. No. 3,665,520. As an example, a gel containing a major component of R SiO, a minor component of vinyl R SiO and small amounts of R.vinyl R SiO and R SiO has been used successfully. Other gels approved for medical use can be used if desired.
The reservoir 14 and shell 12 can be rotationally cast on a mold of the required shape. The mold is dipped in the liquid elastomer and rotated to form the reservoir or container on the outside of the mold. The mold is re peatedly dipped and rotated to cure the elastomer until the assembly has the desired wall thickness. The wall of the containers 12 and 14 formed of this material has little if any rigidity and is very soft and flexible in com-- pression but is known to have a tensile strength satisfactory for this use.
The two containers 12 and 14 are interconnected by means of a tube 16. In this regard, the tube 16 is provided at one end with a flange 17 which is connected to the inside of the container 12. The other end of the tube 16 is bonded to an opening 15 provided in the reservoir 14. Thetube 16 can be reinforced with a fabric 19 such as Dacron or nylon if desired.
The shell 12 is implanted by inserting the shell 12 through a small incision in the patient. The shell can be rolled up and inserted as a tube and the unrolled after implanted or inserted flat, whichever is preferred. The second container or reservoir 14 as seen in FIG. 3 is then squeezed or rolled to force the gel 18 from the reservoir 14 through the tube 16 into the shell 12 to fill the prosthesis. The amount of silicone gel 18 forced into the prosthesis can be determined by observing the graduations 24 provided on the wall of the reservoir 14 and also observing the extent of expansion of the body. After the prosthesis 12 has been filled to the desired size, the tube 16 is tied off with a surgical thread 26. The tube is then cut at 28 to remove the reservoir. The remaining portion of the tube is then folded at the tie thread 26 and sutured or tied by means of a thread 27 to hold the tube in place on the back 22 of the prosthesis 12 as seen in FIG. 4. It should be noted that during this entire procedure, the silicone gel 18 is sealed in the reservoir and is never exposed to the atmosphere and will remain sterile during the entire operation.
Referring to FIG. 5, means are shown for preventing back flow of gel from the first container 12 to the second container or reservoir 14. Such means is in the form of a'one-way valve 30 provided at the end of the tube 16 and within the first container 12. The one-way valve shown is a duck bill type valve having upper and lower resilient flaps 32 and 34 extending into the container 12. The valve 30 allows for the admission of gel into the container 12 but will prevent back flow of gel from the container 12.
Referring to FIGS. 6 and 7, an alternate embodiment of the invention is shown which includes means for sealing the container 12 from the reservoir 14 and for closing both the container and reservoir after implant.
- In this embodiment, a resilient tube 40 made of medical grade material is shown having one end 42 sealed to the reservoir 14 by means of a transverse tube 45 and the flange 46 when the head 56 is seated in the section 48. The slot 60 is used as a guide to determine the location of the point-of cut-off of the tube and to simplify cutting the plug by providing the reduced diameter cutoff section 59.
in regard to this last, after the implant 12 has been filled with the gel, the plug 52 is moved from the section 54 through the tube 40 by squeezing the section 54 and tube 40 behind the plug 12. The gel acts as a lubricant and allows the plug 52 to slide freely into the section 48. The head 56 of the plug 52 will fit snugly within section 48 blocking the flow of gel from the reservoir. The tube 40 and reduced section 59 are then cut at the slot 60. The section 57 remaining in the tube 40 will act as a plug preventing any gel in the tube 40 from flowing out of the tube 40 after the reservoir 14 has been removed.
RESUME The variable volume prosthetic assembly of this invention provides a simple sterile method for implanting a prosthesis. Once filled, the reservoir and container can be stored and shipped without any fear of contamination. The incorporation ofa self-sealing valve or plug into the tube eliminates the possibility of any gel escaping from the implant. After the container or shell has been implanted, the shell can be filled to the extent required to fill out the portion of the anatomy to be augmented. Although prostheses of the type disclosed herein are more commonly used as a breast prosthesis, the prosthesis or container can also be used in other parts of the body either as a replacement or augmentation prosthesis.
