Abstract (en)

[origin: WO9800070A1] The invention provides methods and apparatus for electro-surgically treating tissue within a hollow viscous which includes a physiologic fluid. According to one exemplary method, a surgical instrument (12) comprising an elongate shaft (16) having a proximal end, a distal end, and an active electrode (14) near the distal end, is introduced into the hollow viscous so that the active electrode is surrounded by the physiologic fluid. Current is then passed between the active electrode and a return electrode while focusing the current from the active electrode so that it passes through a desired region of tissue.
