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: 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).
Abstract translation: 套管(2)具有相对于近端部分(4)成角度的远侧部分(6)。 远端部分(6)在引入期间用加强元件(14)矫直。 在引入之后,去除加强元件(14),使得远端部分(6)相对于近端部分成角度,使得套管(2)能够移出外科手术区域。 套管(2)优选地包括具有缝线保持器的稳定环(30)。 稳定环也优选相对于插管(2)成角度。

Abstract: 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.
