ACTIVE SURVEILLANCE OF IMPLANTED MEDICAL LEADS FOR LEAD INTEGRITY

摘要

Active surveillance of potential lead anomalies in implanted medical leads utilizes test signal(s) delivered through an output current pathway and induced signals monitored via an independent monitor current pathway to detect for any reactions to the test signals in the induced signals. Various specific responses can be initiated if a potential insulation breach or anomaly in the implanted medical lead is identified due to detection of a “positive” test result in the induced signals on the monitor current pathway in reaction to a test signal applied to the output current pathway.

主权项

1. An automated method of diagnosing a lead anomaly in an implanted lead of an implantable medical device implanted in a patient comprising:
emitting a test signal through an output current pathway proximate the implanted lead for a test duration; monitoring one or more independent monitor current pathways associated with one or more conductors within the implanted lead during the test duration to generate sensed signals; automatically analyzing the sensed signals for any induced signals on the monitor current pathways in response to the test signals to determine if there are any indications that signify a potential lead anomaly; and if there are any indications that signify the potential lead anomaly, automatically initiating one or more responses to confirm, further diagnose, compensate for, or notify a user of the potential lead anomaly.
