FIELD: medicine.
SUBSTANCE: invention relates to medical equipment, namely, to graft stent, and in particular to a double stent, for overlapping 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 has two coaxially arranged stents. First membrane is arranged between first inner stent and second outer stent. Second membrane comprises second membrane. 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 meets requirements of density and reliability on the one hand, and, on the other hand, provides the required connectivity, and above that, has high radial force.
