摘要： The invention provides a stabilizer (20) having foot (24, 26) to stabilize a patient's heart. The stabilizer (20) has a first foot (24) which is larger than a second foot (26). The first foot (24) has lateral surfaces (54, 54) which are used to retract other parts of the heart while contact surfaces stabilize the target artery.

摘要： 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.

摘要： 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).

摘要： A cannula (2) has a distal portion (6) which is angled relative to a proximal portion (4). The distal portion (6) is straightened during introduction with a stiffening element (14). After introduction, the stiffening element (14) is removed so that the distal portion (6) angulates relative to the proximal portion so that the cannula (2) can be moved out of the surgical field. The cannula (2) preferably includes a stabilizing ring (30) having suture holders. The stabilizing ring is also preferably angled relative to the cannula (2).

摘要： This invention is a method, a device for introduction of a catheter (6C), and/or delivering a fluid, such as oxygenated blood, to a patient's vascular system including a cannula (2C) having an expandable portion (4C). The expandable portion (4C) is movable from a collapsed position to an expanded position. The expandable portion (4C) is inserted into the patient in the collapsed position which facilitates introduction and advancement of the cannula (2C) through the patient's blood vessel. After introduction into the patient, the expandable portion (4C) is moved to the expanded position. The expandable portion (4C) protects the blood vessel against fluid forces when flowing a fluid through the cannula (2C), and protects the vessel from contact with the catheter (6C) advanced through the cannula (2C).
