  • Patent number: 10596307
    Abstract: A blood pump incorporating a rotary pump such as a rotary impeller pump implantable in fluid communication with a ventricle and an artery to assist blood flow from the ventricle to the artery. The device may include a pump drive circuit supplying power to the pump, one or more sensors for sensing one or more electrophysiological signals such as subcutaneous, pre-cordial ECG signals and a signal processing circuit connected to the sensors and to the pump drive circuit. The signal processing circuit is operative to detect the sensor signals and control power supplied to the pump from the pump drive circuit so that the pump may run in a normal sinus rhythm mode, with a varying speed synchronized with the cardiac cycle. When an ischemic or myocardial infarction condition is detected, the pump drive circuit may also run the pump in an ischemia or myocardial infarction mode different from the normal sinus rhythm mode.

  • Publication number: 20180085506
    Abstract: A ventricular assist system including an implantable rotary pump, a pump drive circuit for supplying power to the pump, and a signal processing circuit receiving one or more electrophysiological signals and one or more physiological signals of the subject. The signal processing circuit is operable to receive inputs from the one or more electrophysiological sensors and the physiological sensor, and determine the presence or absence of a non-normal sinus cardiac rhythm condition based on the input from the electrophysiological sensors. In the presence of a non-normal sinus rhythm, the circuit operates the pump in a modified mode of operation. In the absence of a non-normal sinus rhythm, the circuit operates the pump in a normal mode of operation. In either case, the circuit controls the power to the pump and/or speed of the pump based on the input from the physiological sensor and the mode of operation.
