Electrically identifiable electrode lead and method of electrically identifying an electrode lead

An electrical stimulation system, comprising:

• an implantable pulse generator having a connection for at least one lead;
• and
• an electrically identifiable medical electrode lead, comprising
• a flexible lead body having a distal end and a connector end;
• a plurality of electrodes disposed near the distal end of the flexible lead body;
• a connector disposed at the connector end of the flexible lead body, the connector comprising a plurality of contacts;
• a plurality of conductors supported by and passing through the flexible lead body, the plurality of conductors including electrical conductors that provide paths for electrical current from the connector to the plurality of electrodes;
• and
• a first identification module supported by the flexible lead body and being in electrical communication with a contact of the plurality of contacts in the connector,
• wherein the first identification module is coupled to a first electrical conductor and a second electrical conductor of the plurality of conductors, and wherein the first identification module is configured to communicate lead identification information based at least in part on a voltage difference between the first conductor coupled to the first identification module and the second conductor coupled to the first identification module.
