Abstract
A high efficiency electrosurgical ablator which is subjected to a combined oscillatory and mechanical debridement motion during resection of tissue is disclosed. The electrosurgical ablator is positioned in the proximity of the tissue to be treated in the presence of an electrically conductive fluid. A high frequency voltage is applied to the electrode of the ablator, and the electrode is subjected to an oscillatory or other repetitive motion created by an element located within the ablator assembly. The ablator electrode is further connected to a suction assembly that supplies suction from an external source.
