Method and apparatus to manage lead-related conditions for fault tolerance enhancements
First Claim
1. A method of detecting a lead-related condition associated with a medical electrical lead having an electrode and a plurality of conductors, wherein each of the plurality of conductors is coupled to the electrode, the method comprising:
- monitoring signals transmitted through the plurality of conductors;
evaluating the signals for each of the conductors to detect an electrical property indicative of the lead-related condition;
employing an arbitration scheme to select one of the conductors for propagation of a signal sensed by the electrode based on the evaluation; and
coupling the selected conductor to sensing circuitry of an implantable medical device.

Abstract
The disclosure describes systems, methods, and apparatus providing detection mechanism for lead-related conditions, including transient behaviors, on a conductive pathway of a medical electrical lead. In one example, a sense path arbitration module identifies a lead-related condition associated with a conductive pathway based on signal processing to identify transients emerging from a propagated signal. The sense path arbitration module may evaluate a plurality of conductive pathways of the medical electrical lead and arbitrates propagation of a sensed signal that is transmitted through the plurality of lead conductors based on the evaluation. Therapy delivery functions utilizing the medical electrical lead may also be controlled in response to the signal processing and identification of the lead-related condition on a conductive pathway.
