Document Type and Number:

WIPO Patent Application WO2004110259

Kind Code:

A3

Abstract:

Methods and devices for cutting or coagulating tissue. A device comprises an elongate 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 and thermally insulating covering formed on at least the lower surface of the foot member and at least one electrode (26, 28) on the upper surface of the foot member (16). In operation, the at least one electrode (26, 28) is energized so as to cause cutting or coagulation of tissue located above the upper surface of the foot member (16) while not causing substantial damage to tissue located below the lower surface of the foot member(16).
