A centrifugal blood pump driver comprises a motor housing and the housing contains a motor for rotationally driving the centrifugal blood pump and a controller operatively associated with the motor for controlling the rotational speed of the motor; a speed selector for generating a selected speed signal signifying a selected rotational speed for the motor; sensors operatively associated with the motor or controller for sensing the rotational speed of the motor and outputting a monitor signal signifying such rotational speed; program memory for storage of a program of microprocessor readable instructions; a microprocessor under program control, in electrical connection with the controller, the speed selector, the sensor and the program memory, for receiving the selected speed signal and generating a speed control signal to the controller signifying the selected speed for the controller, and for receiving the monitor signal and outputting a display signal; a display in electrical communication with the microprocessor and responsive to the display signal for displaying information; motor housing circuitry for providing electrical communication among the controller, the speed selector, the sensor, the program memory, the microprocessor, and the display; and electrically conductive cable connected to the motor housing circuitry for transmitting electrical DC power to the motor housing circuitry from an external power source.
