摘要：
the invention relates to medicine and can be used in cardiac surgery to replace the affected natural valves of the human heart. a flexible prosthetic heart valve includes a sealing element in the form of three flexible petals 1 connected to the stent \u043a\u043e\u043c\u0438\u0441\u0441\u0443\u0440\u0430\u043c 2, 3, 4 \u0441\u043e\u0435\u0434\u0438\u043d\u044f\u044e\u0449 elastic thread other petals 1.flat petals 1 to conduct elastic filament 4 is performed with a needle 5. a flexible prosthetic heart valve works as follows. in preparation for \u0442\u0440\u0430\u043d\u0441\u043a\u0430\u0442\u0435\u0442\u0435\u0440\u043d\u043e\u0439 prosthesis implantation with stent 3 \u043f\u043e\u0434\u0448\u0438\u0442\u044b\u043c\u0438 petals 1 coagulates along the central axis stent.as the petals 1 made of porous ptfe and shall have a minimum thickness of 0.05 to 0.3 mm, the folded stent 3 with a valve has a minimum diameter to \u043e\u0442\u043e\u0440\u044b\u0439 facilitates the holding of the catheter. using the known procedures used for the \u0442\u0440\u0430\u043d\u0441\u043a\u0430\u0442\u0435\u0442\u0435\u0440\u043d\u043e\u0439 implantation of prosthetic heart valves, the stent 3 installed in the \u0444\u0438\u0431\u0440\u043e\u0437\u043d\u043e\u0435 ring \u043f\u0440\u043e\u0442\u0435\u0437\u0438\u0440\u0443\u0435\u043c\u043e\u0433\u043e tc \u0430\u043f\u0430\u043d\u0430 hearts.after the reconstruction of the heart, the petals 1 made of porous ptfe, starts to curve, allowing direct and limiting the return on the flow of blood through the heart valve prosthesis. however, since the diameter of the elastic threads 4 is greater than or equal to the diameter of the holes 5 for holding the thread 4 formed with a needle, the suture is \u0433\u0435\u0440\u043c\u0435\u0442\u0438\u0447\u043d\u043e\u0441\u0442\u044c\u044e and passes through the blood.moreover, the thread 4, completely fills a hole formed by a needle 5 and prevents stretching holes when a load on the petals 1 to the
