1. A method comprising:
- measuring a first impedance of an at least one conductive sleeve at a first time in an implantable lead assembly, the implantable lead assembly including a lead body having a conductor disposed therein, an electrode coupled to the lead body and in electrical communication with the conductor, an insulating layer surrounds the conductor, and the at least one conductive sleeve is disposed within the insulating layer and surrounds the conductor;
measuring a second impedance of the at least one conductive sleeve at a second time; and
sending a signal if the second impedance is within a predetermined range.

Abstract
An implantable lead assembly includes a lead body extending from a proximal end to a distal end having an intermediate portion therebetween, where the lead body includes an insulating layer. A conductor is disposed within the insulating layer and the insulating layer surrounds the conductor. An electrode is coupled to the lead body, and the electrode is in electrical communication with the conductor. At least one conductive sleeve is disposed within the insulating layer. The at least one conductive sleeve surrounds the conductor and is electrically isolated from the electrode. The at least one conductive sleeve has a first impedance value in a first condition.
