Abstract
A method for treating a tumor excise site defined by a center and edges is described. The method includes simultaneously exposing the tumor site to radiation and pulsating heat. Also described is a device for treating tumors at a target site. The device includes a first balloon containing a radio isotope and a second balloon encasing the first balloon. The second balloon defines structures to create a void between the first balloon and the second balloon such that pulsing, temperature treated fluid traverses the void.
Claims11
A method for treating a tumor excise site defined by a center and edges, the method comprising simultaneously exposing the tumor site to radiation and pulsating heated fluid wherein the radiation emanates from radio-isotopes selected from the group consisting of cesium-133, iodine 125, samarium, ytterbium, palladium, iridium, and combinations thereof and wherein the radio-isotopes are confined to a first void space and detritus is confined to a second void space which encapsulates the first void space.
A method for treating a tumor excise site defined by a center and edges, the method comprising simultaneously exposing the tumor site to radiation and pulsating heat, wherein the pulsating heat establishes a heat gradient wherein regions proximal to the center of the excise site are cooler relative to regions proximal to the edges of the site.
A device for treating a tumor excise site defined by a center and edges, the device comprising:
- a) a reversibly deformable container adapted to receive radio-isotope;
- b) a first temperature sensor at the center and a second temperature sensor at the edges;
- c) a conduit to direct pulsated, heated fluid to the center;
- d) a reciprocating pump harvesting fluid from a remotely situated fluid reservoir for injection into the conduit;
- and
- e) a controller programmed to energize and de-energize the pump when predetermined first temperatures and second temperatures are reached.
