Method and apparatus to manage lead-related conditions for fault tolerance enhancements
First Claim
1. An implantable medical device, comprising:
- a housing including circuitry configured to control a medical function;
a medical electrical lead operative to perform the medical function, the lead having;
a distal end,a proximal end configured for coupling to the housing;
a first conductor extending from the distal end to the proximal end of the lead;
a sensing element electrically coupled to the first conductor at the distal end; and
a signal stability module coupled along a length of the first conductor operative to process a physiologic signal sensed by the sensing element and to generate a lead condition signal based on the sensed physiologic signal, wherein the lead condition signal is a function of an electrical property of the first conductor and is indicative of a lead-related condition associated with the lead.

Abstract
The disclosure describes methods and devices for providing early indicators of a lead-related condition in a medical electrical lead. Among other things, the methods and devices will detect, obtain, or provide indicators of static or intermittent disruptions in a conductive pathway of the lead based on changes in conductive continuity properties of a medical electrical lead. The conductive behaviors and properties will be managed to facilitate signal stability and fidelity. In some embodiments, the methods and devices may include functions to enable one or more of monitoring a lead'"'"'s conductive pathway, detecting static and transient behaviors of the conductive pathway, stabilizing the monitored pathway, reconfiguring the pathway, and providing lead-related condition data to an associated implantable medical device. The early indicators may be generated in a real-time, continuous manner to provide early detection and notification of lead degradation.
