FIELD : medicine.SUBSTANCE : invention relates to medicine, namely, to medical devices – vascular prostheses. Vascular prosthesis contains the inner and outer layers, with the degree of coverage of the inner layer C (%) 15?%≤C≤75?%. In this case, C is determined by the original formula.EFFECT : prosthesis allows to accelerate the formation of a uniform endothelial layer of the vessel, has high reparative functions, and also its use reduces the risk of development of implantation complications.5 cl, 1 tbl, 2 ex, 1 dwg
