ABSTRACT:
A method for installing a ventricular assist device cannula of a novel type including a blood drainage cannula tube having a first end and a second end and a blood inlet cannula tube having a first end and a second end with the tubes being attached together to form a sealed section having a convex outer periphery. The method includes making an opening in a heart, inserting the blood drainage cannula tube through the opening whereby the first end is disposed in a heart chamber and at the same time inserting the blood inlet cannula tube through the opening and also inserting it through the aortic valve so that the first end thereof is disposed in the aorta. At the convex surface, the ventricular assist device cannula is sutured to the heart to hold it in place and to prevent blood drainage therearound. The blood drainage cannula tube is attached to the inlet port of a pump and the second end of the blood inlet cannula tube is connected to the outlet end of the pump whereby this design and method of cannula requires only one opening into the heart instead of two.
