Abstract
A body implantable lead includes a lead body comprising an insulative housing containing at least one conductive polymer conductor terminating within a distal end portion of the lead body at an electrode structure carried by the distal end portion of the lead body. The electrode structure is positioned to contact body tissue to be electrically stimulated and/or sensed. The electrode structure electrically communicates with the at least one conductive polymer conductor by means of an electrically conductive interconnect penetrating the at least one conductive polymer conductor. The at least one conductive polymer conductor terminates within a proximal end portion of the lead body at a terminal contact adapted to be electrically connected to an electrically stimulating/sensing medical device.
Also disclosed are connector assembly, tip electrode and ring electrode structures adapted to be coupled to an implantable lead body containing a conductive polymer conductor.
