Abstract
A lead includes a lead body with a distal end and a proximal end. A plurality of terminals are disposed at the proximal end of the lead body. A plurality of electrodes are disposed at the distal end of the lead body. Each electrode includes an electrode body and at least one anchoring member. The at least one anchoring member couples to the electrode body and extends into the lead body and beneath the electrode body to anchor the electrode to the lead body. A plurality of conductive wires electrically couple the plurality of electrodes to the plurality of terminals.
