FIELD: medicine; vascular surgery .
SUBSTANCE: prosthesis of venous valve represents a tube made of polymer. The prosthesis includes a cylindrical part serving for fastening a prosthesis of venous valve in a vein, a flexible pencil-point transition of decreasing diameter closed and passing to the locking device, formed from a part of the tube with reduced diameter in the form of a tape closed along the perimeter, flat, form-stable, elastically deformed and combined in three, or more, radial bond.
EFFECT: invention improves basic characteristics of a venous valve prosthesis and essentially reduces a retrograde stream.
