Patent ID: 8849403

Claim:
An implantable medical system, comprising: a) an active implantable medical device (AIMD) comprising electronic circuitry hermetically contained inside a device housing, wherein the device housing serves as a conductive equipotential surface; b) a hermetic feedthrough terminal supported by the device housing; c) at least one lead comprising: i) at least one electrical conductor having a length extending from a proximal conductor portion having a proximal conductor end to a distal conductor portion having a distal conductor end, wherein the proximal conductor portion extends through the hermetic feedthrough terminal in a non-conductive relationship with the device housing, and wherein the proximal conductor end is electrically connected to the electronic circuitry housed inside the device housing; ii) at least one biological sensing or stimulating electrode, wherein the at least one electrode is electrically connected to the distal conductor portion or the distal conductor end.; and iii) at least. one electromagnetic interference (EMI) shield surrounding the at least one electrical conductor in a non-conductive relationship therewith, wherein the EMI shield extends along at least a portion of the conductor length, d) wherein a proximal end of the EMI shield by-passes the hermetic feedthrough terminal outside the device housing and is conductively shunted directly to the device housing serving as the conductive equipotential surface.
