Abstract
Embodiments of the disclosed technology are directed to a self-contained, totally implantable blood pump that replaces the whole heart. It is a small spherical device that encloses all of its blood propulsion dynamics. The dynamics are controlled by a built-in microcontroller that regulates the speed of the motor in response to hemodynamic changes like blood pressure fluctuations, level of body activity, and/or posture. The hemodynamic changes are detected using a plurality of sensors disposed around the body. An implantable transcutaneously rechargeable battery provides power to the microcontroller, motor and/or sensors.
Claims22
An artificial heart comprising an artificial right ventricle, and an artificial left ventricle within a housing:
- a first inflow port corresponding to an entrance into said artificial right ventricle from right atrium;
- a second inflow port corresponding to an entrance into said artificial left ventricle from left atrium;
- a first outflow port corresponding to an exit to the pulmonary artery a second outflow port corresponding to an exit to the aorta;
- and
- a microcontroller operatively coupled with said housing of the artificial heart and connected to at least two of the following sensors:
- a pressure sensor placed at a location near the proximal aorta,
- wherein said location is limited to where pressure at said second outflow port is measurable;
- an orientation sensor;
- a vibration sensor;
- and
- a temperature sensor.
An artificial heart with a microcontroller pace maker, said pace maker activating a systole in said artificial heart based on the receipt of data from sensors, said sensors comprising:
- a pressure sensor;
- an orientation sensor;
- a vibration sensor;
- and
- a temperature sensor;
- wherein upon said systole being activated upon a passage of a pre-determined amount of time and a determination that pumping blood from said heart to said body is timely, based on input from at least one said sensor.
