摘要：
Methods and devices for cutting or coagulating tissue. A device comprises anelongate member (14) having a distal end, at least one foot member (16)extending from the distal end of the elongate member, said foot member (16)having a upper surface (US) and a lower surface (LS), an electrically andthermally insulating covering formed on at least the lower surface of the footmember and at least one electrode (26, 28) on the upper surface of the footmember (16). In operation, the at least one electrode (26, 28) is energized soas to cause cutting or coagulation of tissue located above the upper surfaceof the foot member (16) while not causing substantial damage to tissue locatedbelow the lower surface of the foot member(16).
