Abstract

A device for localized diathermy which also includes the potential for simultaneous localized radiation therapy. The device includes tubular element 3 of electrically conductive material in the form of a woven braid. An electrical insulator S is positioned adjacent and abutting the element 3 such that the diathermy treatment associated with electrical current passing through the element 3 is localized to that portion of the element which is uninsulated. Preferably at least one radioactive isotope 7 is positioned within the uninsulated portion of the element such that both the diathermy and the radiation are simultaneously localized. <IMAGE>

Description

SPECIFICATION Medical device for localised therapy This invention relates to a device for medical therapy.
More specifically, the device relates to the therapy of malignant tumors.
In the past, it has been realized that it is desirable to treat tumors by radiation from radioactive isotopes.
Similarly, it has been understoodthattumors may be beneficially treated by diathermy.
The invention related to a device which can provide for localized diathermy and simultaneous localized radiation therapy. The device includes an annulus formed of an electrical conductor which is electrically connected to a suitable conductor for the application of electrical current. The electrical conductor annulus has a plurality of apertures extending radially there- through. Electrical insulation means is positioned adjacent and abutting a portion of the electrical conductor annulus which is uninsulated and which contains at least one radioactive isotope for radiation treatment of the localized area which also receives diathermy treatment.
Figure 7 is a side elevation of the present invention.
Figure 2 is an enlarged fragmentary cross-sectional view taken about 2-2 of Figure 1.
Figure3 is a cross-sectional viewtaken about 3-3 of Figure 3.
Referring to Figure 1, a device for localized diathermy and simultaneous localized radiation therapy treatment, generally referred to as 1, as shown. The device 1 includes an annulus formed of an electrical extending radially outward from the annulus 3. An electrical insulator 5 is positioned adjacent and abutting such electrical conductor annulus 3. In a preferred embodiment the electrical conductor annulus 3 extends byond the uninsulated portion. The electrical conductor annulus 3 is adapted to provide diathermy treatment through the uninsulated portion of the annulus 3 by means of connection to an electrical conductor 17 and an electrical contact 15, adapted for application of radio frequency current, the electrical conductor 17 being insulated by electrical insulator 19.
In a preferred embodiment a plurality of radioactaive isotopes 7 are provided within a sleeve 9 at the uninsulated portion of the annulus 3.
Preferably, the device is positioned adjacent a tumor to receive therapy by passing a reduced diameter portion 11 of sleeve 9 into a hollow rod which is then passed through the body of the patient to receive therapy until the uninsulated portion of the annulus 3 is adjacent the tumor. Stop means 13 prevents the device from being pulled through the area to receive treatment. Preferably, the annulus 3 of a material which conducts electrical current is fabricated of a stainless steel braid, the sleeve 9 is formed of nylon tubing and the electrical insulator 5 is formed from polyethylene.
While illustrative forms of the apparatus and method in accordance with this invention have been described and shown herein, it is understood that numerous changes might be made without departing from the general purposes and scope of this invention.
