Abstract
An electrosurgical tool for cauterizing or ablating targeted tissue, which tool includes a conductive outer shaft which defines a return or reference electrode, and a conductive inner tube disposed within the outer shaft. The inner tube defines both a suction pathway for removing fluid and/or surgical debris from the surgical site through the distal end of the tool, and a pathway for delivering electrical energy to an active electrode secured to the distal end of the suction tube.
