Abstract

See full text

Electrosurgical methods and apparatus for the controlled ablation of tissue from a target site of a patient. The instrument includes a shaft having proximal and distal end portion and a planar active electrode on the distal end portion; a return electrode arranged on the shaft spaced from the active electrode; at least one electrical connector extending through the shaft that connects the active electrode with a high frequency power supply; and an aspiration lumen within the shaft having a distal opening. The active electrode is arranged vertically or perpendicular to the tissue treatment surface. The planar electrode may include one or more apertures.
