FIELD: medicine.
SUBSTANCE: valve-containing graft comprises an internal blocking element in the form of three flexible petals 1, external elements adjoining thereto in the form of convex envelopes 2 and segments of vascular grafts 2 sutured together with an elastic filament 4 passing through holes 5 formed by a needle body. The flexible petals 1, the convex envelopes 2, the segments of vascular grafts 3 and the elastic filament 4 are made of porous polytetrafluoroethylene with a filament diameter 4 is greater or equal to a diameter of the holes 5 formed by the needle when bringing the elastic filament through walls of said elements.
EFFECT: higher graft durability and thrombus resistance, higher safety of the use ensured by lower risk of haemorrhage through the sutures connecting graft elements.
