Abstract

A heart valve prosthesis with a valve ring and at least one substantially elongated wing valve pivotally mounted about an axis located in the plane of the valve ring, in which the bearings of the wing valve or valves are in each case formed by a swivel pin, defining the swivel axis and fixed to the valve ring, a groove constructed in the wing valve and extending therethrough transversely to the axis and whose width corresponds to the diameter and whose depth corresponds to the length of the swivel pin, a first guide pin fixed to the valve ring, a first, convex slide cam constructed on the wing valve and which cooperates with the first guide pin, a second guide pin fixed to the valve ring and a second, convex slide cam constructed on the wing valve and which cooperates with the second guide pin, the spacing from one another of the two slide cams measured over the imaginary connecting line between the centers of the guide pins, in each position of the wing valve, corresponds to the internal, mutual spacing of the two guide pins.
