medicine. SUBSTANCE: means is made from aorta valve complex taken from a mammalian. It has tubular body having distal and proximal end, locking multi-cusp member adjacent to the proximal end of the tubular body. Valve cusps have proportionate valve cusps by dissecting muscular roller of the right coronary cusp of the complex. The right cusp base and the inferior half of the right coronary sinus of the prosthesis are produced from endothelial and subendothelial fibrous tissue being their internal layer and endocardial-subendocardial tissue of the delivering part of the complex and being their external layer. The inferior part of the right coronary sinus has additional external coating produced from at least one tissue layer. EFFECT: improved properties of the prosthesis. 5 cl, 7 dwg |
