    摘要: An aortic cannula tip for reintroducing blood into the blood stream via the aorta. The tip creates a soft flame-shaped flow pattern that reduces the chances of dislodging atheromatous or adherent thromba from the inside surfaces of the aorta. A gentle tapered shape allows the tip to penetrate a small incision made in the aorta without causing undo trauma or risk of tearing. The tip includes a circumferential ridge that allows the tip to be rotated and/or pivoted while in the aorta without breaking a seal formed between the ridge and the aortal wall. A secondary port provides access to a second lumen useable to deploy an intraaortic filtration system.
