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.
