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.

Medical lead with segmented electrodes

An assembly for forming a medical lead includes a lead body, a plurality of electrical conductors extending about a longitudinal axis of the lead body, and at least one segmented electrode preform that includes an electrically conductive ring and an insulator portion within the electrically conductive ring. The electrically conductive ring includes a plurality of electrode portions and a plurality of raised portions that alternate continuously around the ring. Each of the plurality of electrode portions is continuous at a radius from a center of the electrically conductive ring that corresponds to an outer perimeter of the medical lead. The insulator portion has a plurality of projections each extending into a respective raised portion of the ring beyond a radius that corresponds to the outer perimeter of the medical lead. Each respective electrode portion is electrically coupled to a respective electrical conductor of the plurality of electrical conductors.
