Abstract: A medical electrical lead may include a lead body formed to define a first lumen extending from the proximal end to a location near the distal end and having a first central axis. The lead includes an electrode located near the distal end of the lead body and an energy dissipating structure located near the distal end of the lead body, the energy dissipating structure including a conductive main portion that defines a second lumen having a second central axis that is offset relative to the first central axis of the first lumen defined by the lead body and a conductive transition portion that extends towards the first lumen defined by the lead body. A conductor contacts the energy dissipating structure within the transition portion of the energy dissipating structure to provide a substantially continuous interference contact with the energy dissipating structure.
