FIELD: medicine.
SUBSTANCE: invention relates to field of medicine and can be applied in cardiosurgery in operations aimed at replacement of natural heart valves. Prosthesis includes ring-shaped body, limited with upper and lower butt-ends, installed in body with possibility of rotation in order to form clearing section and its blocking locking element made in form of convex-concave cusps, and fold movement limiting elements. In each cusp rectangular slot is made. Fold movement limiting elements are made in form of hook-like protrusions, which have rectangular cross-section for interaction with through slots of folds during their closing or opening. Elements limiting cusp motion are supplied with supports for limitation of fold turning, and in upper butt-end of the body turns are made for interaction with folds when opening or closing and formation of limited reverse blood flow in state of fold closed state.
EFFECT: increase of reliability of fold holding during travel.
