FIELD: medical equipment.
SUBSTANCE: invention relates to a graft stent, and in particular to a double stent to shut off vascular malformations, such as aneurysms and shunts, as well as for strengthening unstable, worn or thrombotic walls of vessels, which, in addition, can be used as an overlapping in branching from stented vessels. Double stent represents a stent with coaxially located stents. First membrane is arranged between first inner stent and at least two outer stents. Second membrane is arranged on outer stents. Ends of the first and second membranes are connected at the ends of the stents, bent on the inner side of the first stent and clamped under the spring lugs of the first stent.
EFFECT: invention satisfies requirements of density and reliability on the one hand, and, on the other hand, provides the required connectivity and, besides, has high radial force.
