Abstract:
1. A medical electrical lead comprising: a lead body having a proximal end configured to couple to an implantable medical device and a distal end; an electrical conductor passing from the proximal end through the lead body toward the distal end; an electrode assembly located near the distal end of the lead body, the electrode assembly including: a tip electrode; a conductive electrode shaft that is electrically coupled to the tip electrode and is electrically coupled to the electrical conductor; and an energy dissipating structure that is coupled to the conductive electrode shaft via a non-electrically conductive material that provides a path to redirect energy induced in the lead by a high frequency signal from the tip electrode to the energy dissipating structure, wherein the electrode assembly further includes a coupling member that physically contacts the conductive electrode shaft and the energy dissipating structure with no metal-to-metal contact occurring between the coupling member and the conductive electrode shaft and wherein there is no electrically conductive path present between the conductive electrode shaft and the energy dissipating structure.
