Abstract
Methods and devices for cutting or coagulating. A device comprises a) an elongate member having a distal end, b) at least one foot member extending from the distal end of the elongate member, said foot member having a upper surface and a lower surface, c) an electrically and thermally insulating covering formed on at least the lower surface of the foot member and d) at least one electrode on the upper surface of the foot member. In operation, the at least one electrode is energized so as to cause cutting or coagulation of tissue located above the upper surface(s) of the foot member(s) while not causing substantial damage to tissue located below the lower surface(s) of the foot member(s).
