Method and apparatus for implanting an aortic valve prosthesis
First Claim
1. A method for percutaneously implanting an aortic valve prosthesis in a beating heart having a septum, left and right atriums, left and right ventricles, a diseased aortic valve, and descending and ascending aortas associated with the beating heart, comprising the steps of:
- percutaneously delivering a portion of a first catheter into the left atrium of the beating heart, the first catheter being associated with a pump;
percutaneously delivering a second catheter into a portion of the descending aorta, the second catheter being associated with the pump;
percutaneously delivering a third catheter into the ascending aorta, the third catheter having an aortic valve prosthesis associated with the third catheter;
disposing the aortic valve prosthesis within the diseased aortic valve and implanting the aortic valve prosthesis within the diseased aortic valve; and
pumping oxygenated blood from the left atrium into the descending aorta, during a period of time while the aortic valve prosthesis is being implanted within the diseased aortic valve.

Abstract
A method and apparatus for percutaneously implanting an aortic valve prosthesis includes a pump for pumping oxygenated blood from the left atrium into the descending aorta, during a period of time in which an aortic valve prosthesis is being implanted within a diseased aortic valve. First and second catheters are associated with the pump, and a third catheter has an end which is adapted for insertion into the ascending aorta, and the third catheter has an aortic valve prosthesis associated with another end of the third catheter.
