ABSTRACT:
A method of obtaining fixation of an animal aortic valve intended for implantation, including subjecting the aortic valve to a tanning fluid at a differential pressure across the valve leaflets in a direction to urge the valve leaflets closed and with the tanning fluid tending to distort the aortic valve. The differential pressure across the valve leaflets is greater than zero and less than about four mm Hg. An insert restrains the valve against substantial distortion during the time the valve is subjected to the tanning fluid.
