Abstract

An implantable heart assist system includes a compressible pumping chamber including an inlet conduit to be placed in fluid connection with the descending thoracic aorta and an outlet conduit to be placed in fluid connection with the thoracic aorta; and a pump system comprising a first rigid member, a second rigid member positioned so that at least a portion of the pumping chamber may be positioned between the first and second rigid members, a drive system configured to cause the second rigid member to move toward or away from the first rigid member, and a controller in operative connection with the drive system and controlling the drive system, wherein movement of the second rigid member toward the first rigid member results in compresses the pumping chamber and movement of the second rigid member away from the first rigid member expands the pumping chamber.
