摘要：
FIELD: medicine.SUBSTANCE: group of inventions refers to medical equipment, namely to devices preventing the gap providing patency or prevent compression of tubular structures of body, and methods of forming said devices. Article for formation of stent has flexible modules of tubular shape, which include frame module and one or more sealing collars. Frame module and collar are made in form of hollow channels made with possibility of filling channels liquid hardening after filling channels. Inner surface of frame comprises a flexible membrane covering space, at least between separate channels. Separate modules of flexible carcass can be connected to each other in place of formation of stent and contain elements compounds, including circular channels located in planes of transverse axis of frame at connection point. Article is made with possibility of its coagulation to tubular shape and a seat of stent delivery. Method of forming stent is characterised by that product to form stent is placed in tool for introduction of article and formation of stent. Hollow channels of article are connected, at least one channel for delivery of hardening liquid. Using tool article is delivered in place of formation of stent is placed at stent, separate modules of article are adjoined to each other and then filled with channels of frame and collars liquid hardening after filling channels.EFFECT: technical result of invention is creation of stents of various shape, including in branching vessels, according to individual size for a specific patient, as well as their reliable installation in vessel of patient.15 cl, 17 dwgГруппа изобретений относится к области медицинской техники, а именно к устройствам, предотвращающим разрыв, обеспечивающим проходимость или предотвращающим сжатие трубчатых структур тела, и способам формирования этих устройств. Изделие для формирования стента содержит гибкие модули трубчатой формы, которые включают каркас модуля и одну или несколько уплотняющих манжет.
