摘要

the u0434u043eu0441u0442u0430u0432u043bu044fu0435u043cu044bu0439 through catheter intravascular stent / implant placed through the operation with minimal surgical intervention.designed for the treatment of several vascular abnormalities, such as aneurysm, u0441u0442u0435u043du043eu0437u044b and anomalies coronary artery shunts, and containing u043fu0435u0440u0435u043fu043bu0435u0442u0435u043du043du044bu0435 tube article u0440u0443u043au0442u0443u0440u044b,the inner of which is surrounded by at least one located u0441u043eu043eu0441u043du043e with additional u0442u0440u0443u0431u0447u0430u0442u043eu0439 structure.in one of the variants of the invention the internal tubular structure has a length formed by a relatively small number of Lu0438 the government was of the u0432u044bu0441u043eu043au043eu044du043bu0430u0441u0442u0438u0447u043du043eu0433u043e u043cu0435u0442u0430u043bu043bu0438u0447u0435u0441one alloy.density and angle of metal was the internal u0442u0440u0443u0431u0447u0430u0442u043eu0439 structures arewhat u043cu0435u0436u0436u0438u043bu044cu043du044bu0435 slits therein are sufficiently large to allow passage of the blood through the membrane, and the diameter of the metal had been selected n thus,to ensure the possibility of the use of the internal u0442u0440u0443u0431u0447u0430u0442u043eu0439 structure as the main component of radial struts / stent implant.part of the internal u0442u0440u0443u0431u0447u0430u0442u043eu0439 structure having the length of l, is surrounded by at least one additional u0442u0440u0443u0431u0447u0430u0442u043eu0439 structureformed by interweaving the relatively large amount of metal used, precluding the possibility of blood through its wall.in u0440u0430u0441u0442u044fu0433u0438u0432u0430u043du0438u0438 assemblies of u043du0430u0441u043bu043eu0435u043du043du044bu0445 tubular structures in the longitudinal direction, it adopts squeezed coherent state, characterized by a reduced diameterto put it in a light delivery catheter. after loading of implant stent, /
