BONE-TREATMENT INSTRUMENT AND METHOD

摘要

Disclosed is a system for palliatively treating a pain-causing tumor on or in bone. The system includes an instrument (286) having a distal-end structure (294) adapted to be inserted into the bone tumor, where the structure (294) is activatable to ablate tumor tissue, and a conduit in the instrument through which a liquid can be supplied to the tumor, when the ablating structure is inserted into the tumor. Also included are a first connecting structure for connecting the distal-end structure (294) to an activating device, such as an RF current source, and a second connecting structure for connecting the conduit to a source of the liquid.
