Segmented electrode
First Claim
1. An electrode assembly adapted to apply stimulation signals to a neuromuscular pathway, the electrode assembly comprising a support structure having an end and an electrode mounted on such end, said support structure comprising a cylindrical tube having an outside diameter, the electrode being cylindrically shaped having an outside diameter equal to that of the support structure and being coaxial therewith, the electrode comprising a plurality of adjacent electrically conductive segments disposed around and collectively forming such end, each segment being electrically isolated from every other segment, each segment adapted for contact with a selected neuromuscular pathway, each segment configured for coupling to a source of stimulation signals so that stimulation signals are deliverable to a selected neuromuscular pathway through one or more of the segments.

Abstract
An electrode having a plurality of electrically conductive segments, each segment being electrically isolated from adjacent segments. The segments are adapted to control living tissue, typically a neuromuscular pathway for delivery of stimulation signals to a desired pathway. The segments may be selectively chosen for the delivery of the stimulation signals, so as to avoid delivery of stimulation signals to tissue in contact with segments not chosen.
