Abstract:
A method and device for occluding a patient's ascending aorta, maintaining circulation of oxygenated blood in the patient and delivering cardioplegic fluid to arrest the patient's heart. An aortic occlusion catheter has an occluding member for occluding the ascending aorta. The aortic occlusion catheter passes through a cannula. Delivery of oxygenated blood is accomplished through either the cannula or the aortic occlusion catheter. In another aspect of the invention, an arterial cannula having a curved or angled distal portion. An introducer straightens the distal portion for introduction into the patient. In still another aspect of the invention, an open-mesh stabilizer is used to stabilize a discoid occluding member.
