Abstract

See full text

An implantable lead includes a lead conductor having a length extending from a proximal end to a distal end. A self-resonant inductor is connected in series along a portion of the length of the lead conductor. The self-resonant inductor includes a single length of conductive material including a dielectric coating substantially surrounding the single length of conductive material. The self-resonant inductor includes a first coiled or spiral conductor disposed along an inductor section spanning in a first direction from a first location to a second location. A second coiled or spiral conductor is disposed along the inductor section spanning in a second direction from the second location to the first location, where the second direction is opposite the first direction. A third coiled or spiral conductor is disposed along the inductor section spanning in the first direction from the first location to the second location.
