Abstract
A method of manufacturing an electrosurgical tool includes the initial step of coupling a proximal end of a substantially malleable elongate tube-like shaft to a distal end of a housing. A tub-like dielectric sheath is disposed on the tube-like shaft. The method also includes the steps of coupling a tube-like electrode having a first thermal conductivity K1 coaxially through the tube-like dielectric sheath and coupling a proximal end of the tube-like electrode to a source of suction to provide fluid communication between the tube-like electrode and the source of suction. The method also includes the steps of electrically connecting the tube-like electrode to a source of energy and coupling a thermally conductive member to the tube-like shaft. The thermally conductive member has a second thermal conductivity K2 that is less than K1 and is configured to impede the propagation of thermal energy proximally.
