AUTOMATIC LEAD IDENTIFICATION USING ELECTRIC FIELD FINGERPRINTING
First Claim
1. A method of identifying a selected one of a plurality of different lead bodies, each of which includes a plurality of proximal contacts and a plurality of distal electrodes respectively electrically coupled to the proximal contacts, the selected lead body being in contact with tissue of a patient, the method comprising:
- conveying electrical energy between the electrodes of the selected lead body and the tissue;
measuring an electrical fingerprint at the proximal contacts of the selected lead body in response to the conveyed electrical energy; and
identifying the selected lead body based on the measured electrical fingerprint.

Abstract
A method, programmer for a neurostimulator, and neurostimulation kit are provided. The kit comprises a neurostimulator, and a plurality of elongated lead bodies configured for being coupled to the neurostimulator, each having a plurality of proximal contacts and a plurality of distal electrodes respectively electrically coupled to the proximal contacts, wherein an in-line connectivity between the electrodes and proximal contacts carried by the different lead bodies differs from each other. Electrical energy is conveyed between the electrodes of the selected lead body and the tissue, an electrical fingerprint is measured at the proximal contacts of the selected lead body in response to the conveyed electrical energy, and the selected lead body is identified based on the measured electrical fingerprint. These steps can be performed by the programmer.
