Document Type and Number:

WIPO Patent Application WO/2016/167399

Kind Code:

A1

Abstract:

The present invention relates to a method for manufacturing a stent and, more particularly, to a method for manufacturing a stent, in which a jig, having a detachable protrusion pin installed at all transition points at which circumference-dividing lines and length-dividing lines cross one another, is used, the circumference-dividing lines and the length-dividing lines being set by equally dividing the circumference (W) and length (L) of a cylinder having the same diameter (R) and length (L) as the stent to be manufactured, and in which cells are formed by intersecting of wires while bending and moving the wires in upward and downward directions such that the wires start from any one reference transition point serving as a starting point and pass through the protrusion pin located in the diagonal direction, wherein a first stent, which is woven such that intersections formed by intersecting of the wires are arranged one by one on each of the length-dividing lines so as to be spaced apart from each other in the diagonal direction, and a second stent, which is woven for the structural stability and warpage prevention of the first stent, may be provided as a single stent.
