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; and 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 energy dissipating structure includes a region having one or more protrusions extending toward a central axis of the lumen defined by the energy dissipating structure to push the coiled conductor off center relative to the central axis of the lumen formed by the energy dissipating structure.
