Method and system for identifying a potential lead failure in an implantable medical device
First Claim
1. A method for detecting potential failures by an implantable medical lead, comprising:
- sensing first, second and third signals between at least first and second combinations of electrodes, on the lead;
determining whether at least one of the first, second and third signals is representative of a potential failure in the lead;
correlating two or more of the first, second and third signals that are representative of a potential lead failure with one another; and
identifying a failure and one or more electrodes associated with the failure based on which of the first, second and third sensed signals is representative of the potential failure and the correlation between the signals representative of the potential failure.

Abstract
A method for detecting potential failures by an implantable medical lead is disclosed. The method includes sensing first, second and third signals between at least first and second combinations of electrodes, on the lead; determining whether at least one of the first, second and third signals is representative of a potential failure in the lead and identifies a failure and the electrode associated with the failure based on which of the first, second and third sensed signals is representative of the potential failure. Optionally, when the first and second sensed signals are both representative of the potential failure, the method further includes determining whether the first and second sensed signals are correlated with one another. When the first and second sensed signals are correlated, the method declares an electrode common to both of the first and second combinations to be associated with the failure.
