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; a conductive electrode shaft located near the distal end within the lead body; a coiled conductor extending within the lead body from the proximal end and coupled to a first end of the conductive electrode shaft; an electrode located near the distal end of the lead body and coupled to an opposite end of the conductive electrode shaft as the coiled conductor; an energy dissipating structure located near the distal end of the lead body and formed from a conductive material that defines a lumen through which a portion of the coiled conductor extends, wherein the portion of the coiled conductor extending through the lumen defined by the energy dissipating structure is formed to provide an interference contact with the energy dissipating structure; and a layer of insulating material covering at least an outer surface of the conductive material of the energy dissipating structure such that the outer surface of the conductive material of the energy dissipating structure does not directly contact a body of the patient when implanted.
