  • Publication number: 20170291023
    Abstract: A lead assembly and a method of making a lead are provided. The method of making a multi-contact lead assembly comprises placing monofilament placed in the void spaces not occupied by the plurality of conductor wires and, in one embodiment, thermally fusing the monofilament to the like material spacer by applying heat just below the melting temperature of the monofilament and spacer material. Alternatively, the monofilament and spacer may be of different materials and heat is applied to cause at least one material to thermally reflow or melt. The conductive contacts may be located at either the distal end and/or proximal end of the lead. Oversized spacers may be used in order to provide extra material to fill voids during the thermal fusion/reflow process.
