Method of making an electrical stimulation lead
First Claim
1. A method of making an electrical stimulation lead, the method comprising:
- individually disposing a plurality of segmented electrodes on a plurality of pins disposed on an interior surface within a mold, wherein each of the segmented electrodes has at least one opening formed in an exterior surface of the segmented electrode to receive at least one of the pins so that the segmented electrodes can be positioned in a predetermined arrangement within the mold with the segmented electrodes spaced apart from each other;
attaching a conductor wire to each of the segmented electrodes;
molding a lead body between the segmented electrodes disposed in the mold; and
removing the lead body, segmented electrodes, and conductors from the mold.

Abstract
A lead with segmented electrodes can be made using one or two mold methods. In one method, segmented electrodes are individually disposed on pins on an interior surface within a mold. Each of the segmented electrodes has at least one opening formed in the exterior surface of the segmented electrode. The lead body is then molded between the electrodes. In a two mold method, segmented electrodes are inserted into electrode slots of a first mold and an interior portion of a lead body is formed. The resulting intermediate arrangement is placed into a second mold to form an exterior portion of the lead body. In another two mold method, a sacrificial ring is formed around the segmented electrodes in a first mold and the resulting intermediate structure is inserted in a second mold to form the lead body. The sacrificial ring is then removed.
