FIELD: medicine.

SUBSTANCE: invention concerns medical equipment, and can be used for replacement of the damaged natural valves of human heart. The skeleton contains a rigid tubular loose leaf with a ring-shaped basis. The flexible element having flexible legs, bridged to its bases is established on the rigid tubular insert. The rigid tubular insert is supplied departing from circinate base in a direction of an axis of the rigid tubular loose leaf by movement terminators. Each flexible leg contains two flexible beams executed with the possibility of a flexure independent from each other. Flexible beams are supplied by the basic racks bridged to the bases by intersections. Each terminator of movement of flexible legs is executed in the form of two rigid teeth, each of which are supplied by basic surfaces, thus rigid teeth are located on perimeter of the tubular loose leaf with interaction possibility the basic surfaces with basic racks of flexible beams.

EFFECT: invention provides dampening of shock load at valve closing.
