METHOD FOR MANUFACTURING BILIARY TRACT STENT AND BILIARY TRACT STENT
Document Type and Number:
WIPO Patent Application WO/2024/082640
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a biliary tract stent and a biliary tract stent. According to the manufacturing method, first wires and second wires can be woven simultaneously, and it is not necessary to wait until weaving of the first wires is completed to start the weaving of the second wires, thereby ensuring the manufacturing efficiency of the biliary tract stent; in addition, in the process of weaving the first wires around a clamp to form first cylindrical mesh structures and weaving the second wires around the clamp to form second cylindrical mesh structures, cross non-self-locking structures can be formed in at least some of regions, and when the biliary tract stent is axially stretched within a certain range, relative movement between different cylindrical mesh structures would occur first, so that deformation of the wires is reduced, thereby reducing the recovery tendency of the biliary tract stent, so as to increase the degree of fitting of the biliary tract stent to the biliary tract structure of a human body, thus reducing the possibility that the biliary tract stent brings an abnormal feeling to a patient at a bent position of a biliary tract.
