Abstract: An example pump thrombosis detection system includes a transducer and processing circuitry. The transducer may be configured to generate a signal representative of a mechanical wave from a mechanical circulatory support device. The processing circuitry is communicatively coupled to the transducer. The processing circuitry may be configured to determine an indication of pump thrombosis based on the signal and, based on the indication of pump thrombosis, control the pump thrombosis detection system to at least one of generate an alert or initiate an intervention.

Abstract: An implantable medical device includes an activity sensor, a pulse generator, and a control module. The control module is configured to determine an activity metric from the activity sensor signal over an activity metric interval and compare the activity metric to a loss of capture detection threshold. The control module may detect loss of capture in response to the activity metric being less than the loss of capture detection threshold and increase a pacing pulse output in response to detecting the loss of capture.
