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 bandstop filter connected in series with the lead wire somewhere along the length thereof, the bandstop filter comprising a capacitor segment having a capacitor segment first end and a capacitor segment second end, and an inductor segment having an inductor segment first end and an inductor segment second end, wherein the capacitor segment first end is electrically conductively connected to the inductor segment first end, and the capacitor segment second end is electrically conductively connected to the inductor segment second end so that the inductor and the capacitor are electrically coupled to one another in parallel; c) wherein the bandstop filter is electrically connected in series with the lead wire somewhere along the length thereof with one of the capacitor and the inductor residing at a proximal location along the length of the lead wire with respect to the other of the capacitor and the inductor residing at a distal location along the length; and d) wherein the inductor segment has an inductor segment inductance and an inductor segment resistance, and the capacitor segment has a capacitor segment capacitance and a capacitor segment resistance.
