Abstract

A medical lead system includes a lead body, a plurality of electrical conductors, and a plurality of electrodes. The lead body may include a distal end and a proximal end defining a longitudinal axis of the lead body. The plurality of electrical conductors extending about the longitudinal axis of the lead body. The plurality of electrodes is positioned around an outer perimeter of the lead body. An inner surface of each of the plurality of electrodes defines an inner perimeter. Each respective electrode of the plurality of electrodes is electrically coupled to a respective electrical conductor of the plurality of electrical conductors. Each electrode of the plurality of electrodes includes at least one electrode locking feature extending into the lead body from the inner perimeter.
