Patent ID: 8571684

Claim:
A lead assembly of an implantable medical device, said lead assembly comprising: an elongated tubular body extending between a proximal connector end and a distal leading end, the body having a plurality of elongated conductors disposed in the body, the connector end of the body having a plurality of conductive terminals coupled with the conductors; a plurality of electrodes disposed on the body and configured to be located at or near an anatomy of interest of a patient, the plurality of electrodes being conductively coupled with the terminals of the body by the conductors, the electrodes configured to at least one of sense electric activity of the anatomy of interest or deliver stimulus pulses to the anatomy of interest; a position tracking sensor disposed in the body and conductively coupled with one or more of the terminals of the body by one or more of the conductors; a first and second electrode of the plurality of electrodes are conductively coupled with a first and second conductor of the plurality of elongated conductors, respectively, and the tracking sensor is conductively coupled in series with each of the first and second electrodes; and wherein the tracking sensor generates an electric position signal representative of a position of the tracking sensor when the body is being implanted into the patient.
