摘要:
the invention belongs to the field of biotechnology and medicine, namely, the technology of \u0431\u0438\u043e\u0440\u0430\u0437\u043b\u0430\u0433\u0430\u0435\u043c\u044b\u0445 polymer fibers, which can be used in etc. \u043e\u0434\u0441\u0442\u0432\u0435 wicker vascular lattice stents.the technical result of the invention is the use of \u0431\u0438\u043e\u0440\u0430\u0437\u043b\u0430\u0433\u0430\u0435\u043c\u043e\u0433\u043e polymer material as the basis \u043c\u043e\u043d\u043e\u0444\u0438\u043b\u0430\u043c\u0435\u043d\u0442\u043d\u043e\u0439 threads coated on the base \u0445\u0438\u0442\u043e\u0437 ana to make vascular lattice stents while maintaining \u043f\u0440\u043e\u0447\u043d\u043e\u0441\u0442\u043d\u044b\u0445 and elastic qualities, improving the speed \u0431\u0438\u043e\u0441\u043e\u0432\u043c\u0435\u0441\u0442\u0438\u043c\u043e\u0441\u0442\u0438 and prediction of intestinal absorption.the basis of the discharge of the \u0433\u043e\u043c\u043e\u043f\u043e\u043b\u0438\u043c\u0435\u0440\u0430 lactic acid or a copolymer of lactic acid with \u0433\u043b\u0438\u043a\u043e\u043b\u0438\u0434\u043e\u043c by forming a polymer tape thickness 0.3 - 0.5 m m and a width of 2 to 4 mm \u0433\u043e\u043c\u043e\u043f\u043e\u043b\u0438\u043c\u0435\u0440\u0430 laminated plating solution of lactic acid or a copolymer of lactic acid with solvent at \u0433\u043b\u0438\u043a\u043e\u043b\u0438\u0434\u043e\u043c in flying dont \u0430\u0434\u0433\u0435\u0437\u0438\u0432\u043d\u0443\u044e to the material basis of substrate.the tape is separated from the substrate and in the length of 75 - 100%, while \u0437\u0430\u043a\u0440\u0443\u0447\u0438\u0432\u0430\u043d\u0438\u0435\u043c around its longitudinal axis. the cover \u0445\u0438\u0442\u043e\u0437\u0430\u043d\u043e\u043c, \u0441\u0448\u0438\u0442\u044b\u043c \u0433\u0435\u043d\u0438\u043f\u0438\u043d\u043e\u043c. get the thread with a diameter of 0.15 to 0.55 mm, with the following composition: the mas.% 80 - 99 coating - 1 - 20.Из
