Title: Aortic cannula with tapered tip

Abstract: An improved aortic cannula is provided for use in heart by-pass surgery. The cannula includes an elongated tube with a terminal end. The terminal end has a ramped surface leading to the discharge opening. The ramped surface terminates in a lip having a tapered leading edge with a point for insertion of the cannula into the aorta. The tapered leading edge spreads a previously made incision to facilitate entry of the terminal end of the cannula into the aorta. With the improved cannula of the present invention, the size of the incision in the aorta is minimized and the damage or tearing of the aorta is eliminated or minimized. This ease of insertion also reduces the time required in the procedure of inserting the cannula into the aorta.
