Abstract
An implantable medical lead connecting to a device header of a medical apparatus and having an electrode, a conductor, and a conductive polymer layer formed on at least a portion of the medical lead. An insulative sheath surrounds the conductive polymer layer for electrical insulation. The conductive polymer layer and insulative sheath maintain mechanical and electrical continuity of the lead in the event of fracture. The conductive polymer layer is composed of conductive polymers and may contain one or more dopants for improving electrical characteristics, mechanical characteristics, and processability.
