Patent ID: 8825177

Claim:
A method for making a medical lead, comprising the steps of: a) providing a lead body comprising a lead body proximal region and a lead body distal region positioned along a longitudinal axis; b) providing at least two insulated conductor wires extending through the lead body proximal region, along the longitudinal axis, to the lead body distal region; c) cutting a notch through the insulation of each of the conductor wires, thereby exposing an area of bare conductor wire; d) placing conductor bands and insulation bands together in an alternating linear fashion along the longitudinal axis and over the at least two conductor wires, wherein the conductor bands are composed of a hydrophilic thermoplastic polyurethane elastomer and disposed intermediate two of the insulator bands to thereby insulate the conductor bands from each other, and wherein the area of bare conductor wire at the notch of one of the conductor wires is in electrical contact with a respective conductor band; and e) heat treating the temporary medical lead so as to create individual electrical connections between a conductor wire and a conductor band.
