Abstract:
An apparatus for treating tissue comprising:(a) an elongated member having a proximal end and a distal end; (b) a plurality of electrically insulated elongated inner tubes, shafts, or conduits contained within and axially traversing the elongated member: each of said inner tubes, shafts, or conduits comprising a lumen: (c) a plurality of elongated independent electrode tines, each electrode tine extending through said inner tubes, shafts, or conduits wherein each said inner tube, shaft, or conduit has a single electrode tine extending therethrough, and wherein each electrodes tine is longer than the elongated member; (d) said tines being insulated proximal to the proximal end of the elongated member; (e) the proximal end of each tine being connected to an energy source; and (f) an actuator mechanism being connected to a segment of each tine; wherein said energy source is an active rotating electrode which provides radio frequency energy in cyclic intervals.
