Abstract
A connection monitoring system for an implantable medical lead system includes an implantable lead, a first trial system cable, an external trial system, and a sensor. The lead has a distal end and at least one proximal end. The lead includes a plurality of terminals disposed at each proximal end. The first trial system cable has a distal end and at least one proximal end. The distal end of the first trial system cable is configured and arranged to electrically couple with the lead. The external trial system is configured and arranged to electrically couple with the first trial system cable. The sensor is electrically coupled to the external trial system. The sensor is configured and arranged for detecting a loss of electrical connectivity between the external trial system and the lead when the lead becomes electrically decoupled from the external trial system.
