WIPO Patent Application WO1999037202

Kind Code:

A3

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).
