  • Method and apparatus for determining aortic valve opening
    Patent number: 10695474
    Abstract: Apparatus for determining opening of an aortic valve of a biological subject, the apparatus including an electronic processing device that determines a pump speed of a ventricular assist device that is assisting cardiac function of the biological subject, analyses the pump speed to determine a pump speed indicator at least partially indicative of changes in pump speed and uses the pump speed indicator to determine an opening indicator indicative of opening of the aortic valve.
    Type: Grant
    Filed: September 22, 2015
    Date of Patent: June 30, 2020
    Assignees: St Vincent's Hospital Sydney Limited, Medical University of Vienna
    Inventors: Marcus Granegger, Francesco Moscato, Heinrich Schima, Christopher Simon Hayward
  • Ventricular assist device method and apparatus
    Patent number: 10610627
    Abstract: Apparatus for use with a ventricular assist device that is assisting cardiac function of a biological subject, the apparatus including an electronic processing device that determines a flow rate of blood through the ventricular assist device, analyses the flow rate to determine a flow parameter value at least partially indicative of a change in the flow rate during diastole; and uses the flow parameter value to either derive at least one blood pressure parameter value at least partially indicative of a blood pressure in the biological subject or control the ventricular assist device.
