Abstract
A method of making a prosthetic heart valve having an occluder which is supported to pivot between open and closed positions in an annular valve body made of pyrocarbon or a pyrocarbon-coated substrate. The valve body contains diametrically opposed pivot supports formed on the interior surface thereof and is distended by subjecting it to diametrically opposed compressive forces of a nature which place extensive exterior regions of the valve body in compression while increasing the distance between the pivot supports. After the occluder is installed in the distended annular valve body, removal of the opposed compressive forces permits the valve body to return to an unstressed, generally circular configuration with the occluder operatively secured between the pivot supports. These forces are applied using flexible, inextensible cables or resilient pressure pads.
