PROSTHESIS OF VENOUS VALVE Russian patent published in 2008 - IPC A61F2/06 A61F2/24 A61F2/04

Abstract RU 2332960 C1

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.
