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.
Claims38
An implantable medical lead comprising:
- a conducting electrode comprising:
- a proximal end for receiving or delivering electrical signals;
- and
- a distal end;
- a conductor comprising:
- a body;
- a proximal end connected to the distal end of the conducting electrode to form a first electrical connection;
- and
- a distal end for connection to a device header to form a second electrical connection;
- a conductive polymer positioned adjacent a length of the conductor and in electrical contact with the conductor along at least a portion of the length of the conductor;
- and
- an insulating sheath surrounding the conductive polymer to electrically insulate a surface of the conductive polymer.
