Abstract
An implantable lead in the form of an electrical conductor wire having an insulating layer of impervious plastic surrounding the surface of the electrical conductor wire and further having an exterior surface covering of porous PTFE. The impervious plastic insulating layer is preferably a thermoplastic and most preferably a thermoplastic fluoropolymer such as ETFE, FEP or PFA. The exterior surface covering of porous PTFE offers improved flexibility and biocompatibility in comparison to conventional lead wires having silicone exterior surfaces, while the impervious plastic insulating layer prevents loss of insulating integrity resulting from wetting out of the porous PTFE exterior surface by body fluids. Methods of making the implantable lead are also described.
