摘要： 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.

摘要： In some examples, a medical system includes one or more trialing leads implanted within a patient, one or more sensors configured to determine a value for a sensed parameter indicative of an activity level of the patient, and processing circuitry. The processing circuitry may be configured to receive the value from the one or more sensors, determine whether the value is outside a threshold range, and—in response to determining that the value is outside the threshold range—generate information indicating a status of the one or more trialing leads. In some examples, processing circuitry may be configured to output an alert warning that patient movement could dislodge, or has already dislodged, the one or more trialing leads.
