Claim 10:
11. An apparatus for a heart of a patient comprising:
a cardiac assist device adapted to be implanted into the patient to assist the heart with pumping blood, the cardiac assist device has a shaft that is adapted to be positioned in the heart, the cardiac assist device includes a motor and an impeller disposed in the shaft which is driven by the motor to assist the heart with pumping blood, the pump draws blood from a left ventricle of the heart through an inlet port of the shaft and expels blood into an ascending aorta of the heart through an outlet port of the shaft, thereby reducing some mechanical load on the heart and promoting recovery;
a sensor adapted to be implanted into the patient, the sensor in direct contact with the shaft of the cardiac assist device and in communication with the heart which monitors the heart based only on impedance while the cardiac assist device is in operation; and
a pressure sensor adapted to be implanted into the patient, the pressure sensor in contact with the shaft of the cardiac assist device and in communication with the heart and which monitors left ventricular pressure while the cardiac assist device is in operation and with the computer plots native pressure volume loops while the cardiac assist device is in operation.
