Abstract:
1. A lead for use with an implantable cardiac stimulus device (ICSD) comprising: an elongated flexible body portion having a proximal end configured for coupling to a canister of the ICSD and a distal end, the elongated flexible body comprising a plurality of filars extending through an insulating sheath, wherein the insulating sheath includes a gap near the distal end; and an electrode having a first face and a second face, an appendage on the second face for use during implantation, and a fastener for coupling the electrode to the distal end of the elongated flexible body; wherein: the electrode comprises a metallic mesh exposed on the first face and generally covered on the second face; the lead fastener comprises a metal strip, a crimping tube and a crimping pin; the metal strip has first and second ends that are attached to the metallic mesh and a first crimp point between the first and second ends; the crimping tube has a second crimp point; the filars are disposed between the crimping tube and crimping pin such that the second crimp point squeezes the filars between the crimping tube and the crimping pin; and the crimping tube forms an electrical connection between the filars and the metallic mesh.
