Abstract
A heart valve prosthesis has a substantially annular valve body and two leaflets which are disposed in the valve body and, be means of a hinge mechanism, are pivotable between an open position and a closed position. The leaflets are substantially semicircular and evenly curved in two perpendicular directions, one direction being perpendicular to the diameter of the semicircle, so as to bulge outward, as seen from the center of the annulus. The leaflet edges closest to the diameter of the semicircle are so curved that they, when the valve is closed, are applied against one another along their entire length. Further, two projections are provided on the inside of the annulus, entirely within the width thereof, the corner portions of the leaflets being applied against these projections.
