Abstract: An apparatus and method for use in assisting a human heart are disclosed. The apparatus comprises an aortic compression means which may be fully implanatable, a fluid reservoir and a pump means adapted to pump a fluid from the reservoir to the aortic compression means so as to actuate the aortic compression means at least partly in counterpulsation with the patient's heart. In addition, the device is adapted to be wholly positioned within the right chest cavity of the patient. The aortic compression means of the device may be curved along its length so as to substantially replicate the curve of the ascending aorta.

Abstract: A fluid pressure generating means (10) for a heart assist device having blood pumping means. The pressure generating means (10) includes a housing (11), defining an interior volume (18), and having a substantially rigid first housing portion (12), a substantially rigid second housing portion (14), a flexible third housing portion (16) extending between the first (12) and second (14) housing portions and an inlet/outlet port (15) adapted for fluid communication with the blood pumping means. The pressure generating means (10) also includes a fluid filling the housing and a motor (20) disposed within the housing (11) and connected between the first (12) and second (14) housing portions. Actuation of the motor (20) moves the first (12) and second (14) housing portions relative to one another to generate fluid pressure changes at the inlet/outlet port (15). A related heart assist device and method for the treatment of congestive heart failure, myocardial ischemia and like conditions are also disclosed.

Abstract: Apparatus and method for performing a heart assist function by use of intraluminal inflatable counter-pulsation balloon or chamber. The apparatus includes means to hold the balloon or chamber in place against an inner wall of a blood vessel. The balloon or chamber is connected to a source of pressure which expands and contracts the balloon in counter-pulsation with the heart.

Abstract: An implantable device (10) for assisting the functioning of the heart of a patient. The device (10) includes compressing means (14) adapted to be positioned about the aorta (12) of a patient for externally engaging and compressing the aorta (12) and means (30) for releasing the compressing means (14) from about the aorta (12). The releasing means (30) being adapted for releasing in response to intracorporeal input during minimally invasive surgery or in response to intracorporeal input. The device (10) is connectable to motive means adapted to activate the compressing means (14). The compressing means (14) and the releasing means (30) are fully implantable within the thoracic cavity of the patient.
