Abstract:
1. An implantable device, comprising: a) at least one lead conductor having a length extending from a proximal conductor end to a distal conductor portion having a distal conductor end, wherein the proximal conductor end is electrically connectable to an active implantable medical device; b) at least one electrode electrically connected to the distal conductor portion or the distal conductor end, wherein the electrode is contactable with biological cells; and c) wherein the at least one lead is a coiled conductor comprising at least two portions of varying spacing between adjacent turns, the at least two portions comprising a first spacing portion having a larger spacing between adjacent turns as compared to a second spacing portion; d) wherein the first spacing portion comprises a first inductance formed from the turns of the single coiled conductor along the first spacing portion; and e) wherein the second spacing portion comprises a bandstop filter comprising a self-resonant inductor, wherein the self-resonant inductor comprises a second inductance formed from the turns of the single coiled conductor along the second spacing portion and e) wherein a bandstop filter capacitance comprises parasitic capacitance formed between the adjacent turns of the coiled conductor along the second spacing portion.
