Abstract: Blood circulation assist systems include a ventricular assist device (VAD), a remote accelerometer, and a controller that controls operation of the VAD based on output of the remote accelerometer. A blood circulation assist system includes a VAD, a controller, and a remote accelerometer. The VAD includes an impeller. The remote accelerometer is configured to generate a remote accelerometer output indicative of accelerations measured by the remote accelerometer. The implanted controller controls a rotation speed of the impeller based on the remote accelerometer output.

Abstract: Circulatory support systems and related methods are disclosed in which a ventricular assist device is controlled based on cardiac activity monitored via cardiogram electrodes. A circulatory support system includes a ventricular assist device, cardiogram electrodes, and a controller. The controller processes a cardiogram signal generated via the cardiogram electrodes to determine one or more physiological parameters indicative of an activity level and/or cardiac cycle timing, determines at least one operating parameter for the ventricular assist device based on the one or more physiological parameters, and controls operation of the ventricular assist device in accordance with the at least one operating parameter.
