Abstract:
Apparatus for carrying out the cauterization of a volume of abnormal tissue of given peripheral extent utilizing the applied electrical outputs, including a return, of an electrosurgical generator, comprising:a support member extending between a tip and a base region, having a forward end region extending along a longitudinal axis from said tip and positionable in an insertion mode into adjacency with said tissue volume peripheral extent, said forward end region having an electrode deployment portion;a first electrode assembly, having a primary component of predetermined longitudinal dimension extending within said deployment portion in said insertion mode, deployable, in an electrosurgical cutting deployment mode, outwardly from said electrode deployment portion to a first cauterization orientation adjacent said tissue peripheral extent; andan actuator and electrical circuit assembly extending along said support member from said base region, mechanically connected with said first electrode primary component for effecting said deployment thereof, and having a terminal assembly electrically connectable with said generator for coupling a first said applied output to said first electrode primary component providing, in operative association with a said return, electrosurgical cutting of tissue adjacent said peripheral extent during said electrosurgical cutting deployment mode, said terminal assembly conveying a second said applied output from said generator as a cauterization current to said first electrode assembly when said first electrode primary component is at said first cauterization orientation.
