1. A method for forming a lead, the method comprising:
- placing a plurality of electrodes into a spaced-apart arrangement, each electrode of the plurality of electrodes comprising an electrode body, at least one anchoring member extending beneath the electrode body, and one or more teeth disposed along the at least one anchoring member;
forming a lead body around the plurality of electrodes with the electrodes disposed at a distal end of the lead body, the lead body also formed around the at least one anchoring member of each of the plurality of electrodes;
anchoring the electrode body to the lead body using the one or more teeth disposed along the at least one anchoring member; and
electrically coupling each of the plurality of electrodes to a plurality of terminals disposed on a proximal end of the lead body.

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.
