Abstract

An implantable heart assist system, includes a pumping chamber formed of a flexible material and being adapted to be placed in fluid connection with the aorta and a pump system comprising a first rigid member and a spaced apart second rigid member so that at least a portion of the pumping chamber may be positioned therebetween, a drive system comprising a motor. The motor is adapted to cause the second rigid member to move toward the first rigid member to compress the pumping chamber or away from the first rigid member to expand the pumping chamber. A controller is in operative connection with the drive system and controlling the motor.
