Fracture resistant medical electrical lead

摘要

An implantable medical lead provided with a coiled conductor extending from a connector assembly at a proximal end of the lead to an electrode on the lead body and a stranded conductor extending from the connector assembly to a point distal thereto. The stranded conductor is coupled to the coiled conductor at both of its ends and provides both for an increased resistance to fracture of the coiled conductor and a redundant conductor in case the coiled conductor does fracture.
