Patent ID: 8286339

Claim:
A method of manufacturing an electrosurgical tool, comprising the steps of: coupling a proximal end of a substantially malleable elongate tube-like shaft to a distal end of a housing, the tube-like shaft having a tube-like dielectric sheath disposed at least partially thereon; coupling a tube-like electrode having a first thermal conductivity K 1 coaxially through the tube-like dielectric sheath; coupling a proximal end of the tube-like electrode to a source of suction via a lumen to provide fluid communication therebetween; electrically connecting the tube-like electrode to a source of energy to provide energy to tissue via the exposed distal end of the tube-like electrode; and coupling a thermally conductive member to the tube-like shaft, the thermally conductive member having a second thermal conductivity K 2 that is less than K 1 , the thermally conductive member being configured to impede the propagation of thermal energy proximally from the distal end of the tube-like shaft.
