Patent ID: 8221483

Claim:
An implant assembly, comprising: an elongated pusher member having a proximal end and a distal end, the pusher member comprising an electrically conductive stiffening member and a first electrically conductive sheath disposed over, and electrically isolated from, the stiffening member; an implantable device mounted to the distal end of the pusher member; an electrolytically severable joint disposed on the pusher member, wherein the implantable device detaches from the pusher member when the severable joint is severed; a first terminal located on the proximal end of the pusher member, wherein the first terminal is in electrical communication with the severable joint via the stiffening member; a return electrode located on the distal end of the pusher member in proximity to, but electrically isolated from, the severable joint, wherein the return electrode is coupled to a second terminal carried on the proximal end of the pusher member via the first electrically conductive sheath; and a second electrically conductive sheath disposed over the stiffening member, wherein the second electrically conductive sheath is electrically isolated from the first electrically conductive sheath, and wherein the electrically conductive stiffening member is coupled to the first terminal via the second electrically conductive sheath.
