Patent ID: 8676345

Claim:
A lead comprising: a lead body having a distal end; a plurality of electrodes disposed at the distal end of the lead body, wherein each of the plurality of electrodes comprises a unitary ring and a seat in the unitary ring, wherein the unitary ring has a circumference, an exterior surface, and an interior surface, wherein the seat is a first region of the unitary ring that is radially depressed with respect to a second region of the unitary ring adjacent the first region, wherein the seat extends around a portion of the circumference of the unitary ring that is less than an entire extent of the circumference with the second region of the unitary ring extending in both clockwise and counter-clockwise directions around a remaining portion of the circumference of the unitary ring relative to the seat, the seat comprising an exterior surface that is contiguous with the exterior surface of the unitary ring; and a plurality of lead wires, each extending along the lead body and attached directly onto, and in contact with, the exterior surface of the seat of a corresponding one of the plurality of electrodes producing an electrical coupling between the lead wire and the corresponding one of the plurality of electrodes.
