Electrosurgical devices and methods for selective cutting of tissue

A method for selective electrosurgical cutting or coagulation of tissue, said method comprising the steps of:

• A) inserting a device which comprises;
• an elongate member having a distal end;
• a bifurcated foot member that extends angularly from, and to one side of, the distal end of the elongate member, said bifurcated foot member comprising a right foot member portion having an upper surface, an inner edge and a lower surface and a left foot member portion having an upper surface, an inner edge and a lower surface, the inner edges of the right and left foot member portions being juxtaposed to each other and an open area existing therebetween;
• an electrode on the upper surface of the right foot member portion;
• an electrode on the upper surface of the left foot member portion;
• and
• an electrically and thermally insulating covering formed on at least the lower surfaces of the right and left foot member portions;
• B) positioning the device such that tissue that is to be cut or coagulated is located directly above the open area that exists between said inner edges;
• and
• C) energizing the electrodes to thermally cut or coagulate tissue located above the open area that exists between said inner edges, without causing substantial thermal cutting and/or coagulation of tissue located below the lower surfaces of the right and left foot members.
