Claim:
1. An implantable heart assist system, comprising: a compressible pumping chamber comprising an inlet conduit configured to be placed in fluid connection with the descending thoracic aorta and an outlet conduit configured to be placed in fluid connection with the thoracic aorta; and a pump system comprising a first rigid member, a second rigid member spaced from the first rigid member so that at least a portion of the pumping chamber may be positioned between the first rigid member and the second rigid member, a drive system comprising a motor and an actuator mechanism to convert rotary motion of the motor to linear motion to cause the second rigid member to move toward the first rigid member or away from the first rigid member, and a controller in operative connection with the drive system and controlling the motor, movement of the second rigid member toward the first rigid member causing compression of the pumping chamber and movement of the second rigid member away from the first rigid member causing expansion of the pumping chamber, the first rigid member being configured to be positioned adjacent the chest wall posterior to the thoracic aorta and the second rigid member being configured to be positioned adjacent the surface of the left lung.
