Abstract: A circulatory support system includes an implantable blood pump including a housing, a rotor operable to pump blood from an inlet to an outlet, a stator, and at least two of the following: a current sensor, a rotor position sensor, an accelerometer, and a pressure sensor. The controller is connected to the sensors and includes a signal-processing module configured to receive, from each of the sensors, a data stream. The signal-processing module is also configured to filter the data streams received from the plurality of sensors, determine at least one of a pump operating parameter, a cardiac characteristic, and a pump control parameter based on at least two of the filtered data streams, and output the at least one of the pump operating parameter, the cardiac characteristic, and the pump control parameter to at least one of the operator interface module and the pump control module.

Abstract: A blood circulation assist system includes a ventricular assist device (VAD) and a controller. The VAD is attachable to a heart of a patient to pump blood from a ventricle of the heart into a blood vessel of the patient. The VAD includes an impeller, a motor stator operable to rotate the impeller, and an accelerometer generating an accelerometer output indicative of accelerations of the VAD. The controller controls operation of the motor stator to control rotational speed of the impeller based on the accelerometer output.
