Patent ID: 8688217

Claim:
An implantable pulse generator for coupling to a lead with a distal end and a proximal end, the lead comprising at least one terminal disposed at the proximal end, the implantable pulse generator comprising: a housing; an electronic subassembly disposed within the housing and configured and arranged to generate electrical pulses; a connector for receiving the proximal end of the lead, wherein the connector further comprises a first contact and a second contact electrically isolated from one another and spaced apart from each other, the first and second contacts are configured and arranged to become electrically coupled to one another when the lead is fully inserted into the connector with a same terminal of the lead physically abutting, and conductively coupling to, both the first contact and the second contact, wherein the first contact and the second contact are configured and arranged to remain electrically isolated from one another when the lead is not fully inserted into the connector; and a sensor electrically coupled to the first and second contacts and configured and arranged for detecting electrical connectivity between the implantable pulse generator and the lead.
