Abstract
A device and method 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 device has an occluding member in the form of a non-inflatable structure which is moved mechanically between collapsed and expanded orientations. The device is introduced into the ascending aorta in its collapsed orientation and is moved to its expanded orientation to occlude the aorta. The aortic occlusion includes a lumen through which blood is delivered to the patient. The lumen may be provided in the aortic occlusion device or in a separate cannula coupled to the device.
