Patent ID: 7891085

Claim:
A method of manufacturing a stimulation lead having a proximal end and a distal end, comprising: providing a plurality of conductive contacts located at an end of a lead body of the stimulation lead; disposing a plurality of conductor wires in a plurality of conductor lumens formed in the lead body; connecting at least one of the plurality of conductor wires to each of the conductive contacts; placing spacers between pairs of adjacent conductive contacts, wherein portions of the conductor lumens are located beneath the plurality of conductive contacts and the spacers; inserting monofilament into at least one portion of at least one of the conductor lumens of the lead body that is not occupied by the conductor wires; and reflowing at least one of the spacers or monofilament into at least one portion of at least one of the conductor lumens not occupied by the conductive wires by heating the spacers and monofilament to a temperature to cause thermal flow or melting of at least one of the spacers or monofilament.
