Abstract:
1. A lead wire system for use with an active implantable medical device, the lead wire system comprising: a) an implantable lead comprising at least one lead wire having a length extending to and meeting with a proximal lead end and a distal lead end; b) a tank filter as a permanently passive circuit comprising a coiled conductor having parasitic capacitance between adjacent turns of the coiled conductor to provide a self-resonant inductor, wherein the tank filter is electrically connected in series with the lead wire somewhere along the length thereof; c) wherein the inductor has an inductance and an inductor series resistance (R d) wherein the inductor series resistance and the capacitor series resistance result in the tank filter having a Q wherein the resultant 3 db bandwidth is on the order of megahertz.
