Abstract
Electrosurgical systems, apparatus and methods for selectively applying electrical energy to body tissue in order to ablate, contract, coagulate, or otherwise modify a target tissue of a patient. An aspect of the invention includes an active electrode assembly having two active electrodes which may be controllably selected to vary the level of energy applied to the tissue. An electrosurgical apparatus of the invention includes a shaft having an articulated electrode support at a distal end of the shaft, the electrode support bearing at least one active electrode on a surface of the electrode support.
