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.
