Patent ID: 8646172

Claim:
A method of manufacturing a stimulation lead comprising: providing a lead body comprising an insulation section, the insulation section defining a central lumen extending along the insulation section and a plurality of conductor lumens extending along the insulation section and arranged around, and external to, the central lumen, the lead body further comprising a plurality of conductive contacts located along an axial end of the lead body, and a plurality of conductor wires, wherein each of the conductor wires is disposed within one of the plurality of conductor lumens and each of the conductor lumens of the plurality of conductor lumens has at least one of the conductor wires of the plurality of conductor wires disposed therein, wherein a portion of the conductor lumens is disposed radially beneath the conductive contacts; after providing the lead body, conductively coupling at least one of the plurality of conductor wires to each of the conductive contacts; and after providing the lead body, placing non-conductive material into a portion of at least one of the conductor lumens of the lead body, wherein at least a portion of the non-conductive material is disposed radially beneath the conductive contacts.
