Lead body with thermoplastic polyurethane adhesive

Abstract

One aspect is a method of forming a lead body comprising providing a plurality of individual conductors between a proximal end and a distal end of the lead body. Each one of the plurality of individual conductors is coupled to one electrode of a plurality of electrodes. An outer cover is placed over the plurality of individual conductors and over the electrodes in a substantially cylindrical shape with an outer diameter, leaving a distal opening in the cover at the distal end, the distal opening having a same diameter as the outer cover. The outer cover comprises a first thermoplastic material that hermetically seals the lead body. An adhesive cap is applied to the outer cover and fully over the distal opening thereby closing the distal end, wherein the adhesive comprises the first thermoplastic material.
