Zusammenfassung:A medical electrical lead may include 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, and 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. The lead may also include an energy dissipating structure located near the distal end of the lead body and defining a lumen through which a portion of the coiled conductor extends. The energy dissipating structure may include a region having one or more protrusions extending toward a central axis of the lumen to push the coiled conductor off center relative to the central axis of the lumen.
