Abstract: This invention is a method, and device for occluding a patient's ascending aorta, maintaining circulation of oxygenated blood (72) in the patient, and delivering cardio-plegia fluid (64) to arrest the patient's heart. An aortic occlusion catheter has an occluding member (4) for occluding the ascending aorta. The aortic occlusion catheter (2) passes through a cannula (28). Delivery of oxygenated blood (72) is accomplished through either the cannula (28) or the aortic occlusion catheter (2). In another aspect of the invention, an arterial cannula (28) has a curved or angled distal portion (40). An introducer (50) straightens the distal portion (40) for introduction into the patient. In still another aspect of the invention, an open-mesh stabilizer (172) is used to stabilize a discoid occluding member (4K).

Abstract: The valve implantation system has a valve displacer (8) for displacing, and holding the native valve leaflets open in a first aspect of the invention. A replacement valve (6) may be attached to the valve displacer before or after introduction, and may be positioned independent of the valve displacer. In another aspect of the invention, the valve displacer and the valve are in a collapsed condition during introduction, are expanded to deploy the valve displacer, and valve. The valve is a tissue valve (38) mounted to an expandable support structure (26). The support structure may have protrusions (34) for engaging the valve displacer or barbs for anchoring the valve displacer to the heart or blood vessel. A temporary valve mechanism (40) may be used to provide temporary valve functions during, and after deployment of the valve displacer.
