Abstract
Leakage of signal between conduction paths of an implantable medical lead or lead and lead extension combination is detected. A stimulation signal is provided via one electrode. Two other electrodes sense the stimulation signal. A difference in amplitude of the two sensed signals is determined and based on this difference, leakage is detected. A sensing circuit may use differential amplification of the two signals and compare a resulting output signal to a leakage threshold. When the amplitude of the output signal exceeds the leakage threshold, then leakage is occurring between the conduction path providing the stimulation and one of the conduction paths used for sensing. Other techniques for determining leakage from the difference may also be used such as comparing the amplitudes of the two sensed signals and providing a value that is based on the comparison to indicate whether leakage is present.
