Abstract

A surgical device comprises a tip portion (14) including first and second jaws (16a, 16b) each having a tissue grasping surface, at least one of the jaws being movable toward the other. The tissue grasping surface of each jaw includes an electrically insulative surface. The device also includes first and second electrodes connectable to an RF generator. One of the electrode surfaces is located on one of the jaws separated from one edge of the tissue grasping surface, and the other of the electrode surfaces is located on one or the other of the jaws separated from the other edge of the tissue grasping surface. The device also includes at least one fluid passage.
