Interstitial heating of tissue
First Claim
1. A medical system for interstitial heating of a solid mass within a body of a living being, comprising:
- an elongated, rigid implement having a sharp distal end and constructed for insertion into said solid mass through a puncture site in said solid mass created by said sharp distal end,an elongated sleeve constructed to engage said elongated, rigid implement and constructed to enter said solid mass through said puncture site in said solid mass and to extend into said solid mass,an expandable chamber located in the vicinity of a distal end of said elongated sleeve,at least one channel located within said elongated sleeve to provide a fluid to said expandable chamber for inflation of said chamber while said chamber is positioned interstitially within said solid mass,a heating device located within said expandable chamber for heating said fluid within said chamber while said chamber is filled with said fluid, andat least one elongated conductor located within said elongated sleeve and connected to said heating device to power said heating device while said chamber is positioned interstitially within said solid mass and is filled with said fluid.

Abstract
An elongated, rigid implement having a sharp distal end is insertable into a solid mass within the body of a living being through a puncture site in the solid mass created by the sharp distal end. An elongated sleeve, which engages the elongated, rigid implement, is insertable into the solid mass through the puncture site in the solid mass. Fluid is provided to an expandable chamber located in the vicinity of a distal end of the elongated sleeve through at least one channel located within the elongated sleeve, to inflate the chamber while the chamber is positioned interstitially within the solid mass. A heating device located within the expandable chamber is powered, through at least one elongated conductor located within the elongated sleeve, to heat fluid within the chamber while the chamber is filled with the fluid and is positioned interstitially within the solid mass. The inflation of the chamber while the chamber is positioned interstitially within the solid mass causes compressive ischemia of tissue surrounding the chamber, and the compressive ischemia of the tissue surrounding the chamber reduces a heat sink effect of the tissue during powering of the heating device.
