MANUFACTURING METHODS FOR ANTI-MIGRATION STENT AND THE ANTI-MIGRATION STENT THEREOF

摘要

The present invention relates to a manufacturing method of an anti-slip stent and an anti-slip stent manufactured thereby. More particularly, an anti-slip stent is formed as a hollow body (3) having a plurality of spaces having a shape of rhombus by weaving superelastic shape-memory alloy wires (2) in a diagonal direction so as to allow an upper line (2a) and a bottom line (2b) to cross each other from the top and the bottom. Further, a rod is inserted and fixated below the wires (2) in the hollow body (3) and a shoulder bump (5) corresponding to the cross-sectional shape of the rod is formed on the wire by bending so as to vertically protrude in a diagonal direction. Thus, the anti-slip stent is easy to be manufactured, while supporting inner cavity so as to prevent slipping inside human bodies by having the shoulder bump (5) vertically protruding in the diagonal direction of the hollow body. Also, the anti-slip stent can be inserted into the inner cavity and can be easily separated while preventing a conventional problem of damaging inner wall by poking the inner wall in the process of inserting and separating the stent.
