CARDIAC VALVE PROSTHESIS Russian patent published in 2008 - IPC A61F2/24 

FIELD: medicine.

SUBSTANCE: invention relates sphere of medical technique and can be used in cardiosurgery. Prosthesis contains frame with two beads and blocking element as three similar convexoconcave cusps. Frame inner surface in its upper part is created with three pairs of cylindrical intersecting surfaces of the same diameter. Geometric axes of these cylindrical surfaces are dislocated from the geometric axis of the external surface on the distance equal to 1/8-1/4 of external cylindrical surface diameter. Cylindrical surface in every pair are turned one to another around the external surface axis on the angle of 18-40°. Pairs of cylindrical surfaces are turned one concerning another on 120°. In places of cylindrical surfaces intersection on the frame are created the six ledges of two different sizes. On the inner side of the body frame three ledges of one size take turns next to one with three ledges of another size. In ledges of more size semispheric deepings are made complying the semispheric ledges of cusps. Ledges of less size define the position of peripheral edge of every closing element cusps in close position.

EFFECT: reliability increasing of cardiac valve.
