Abstract
Provided is a method for manufacturing a stent having a superior bending characteristic, in which a basic jig is employed to weave wires by alternating an obtuse angle and an acute angle so as to repetitively form starry cells in left and right portions and upper and lower portions of the stent, and in which the wires intersecting each other in the starry cells are allowed to freely move to provide the superior bending characteristic caused by flexibility in both the diametrical direction and lengthwise direction thereof, and the stent manufactured thereby. Thus, the stent can have a flexible bending characteristic and is prevented from being folded even when sharply bent after being coated.
Claims4
A stent having bending characteristics comprising:
- an upper head including a plurality of rhombic cells;
- a lower head including a plurality of rhombic cells;
- and
- a middle body including a plurality of starry cells,
- wherein each of the plurality of rhombic cells are formed by crossed wires, and
- wherein each of the plurality of starry cells are formed by wires having acute angle bending vertexes bent at an acute angle, and obtuse angle bending vertexes bent at an obtuse angle, such that the acute bending vertexes and the obtuse bending, vertexes are joined crosswise between the upper and lower heads, and the obtuse angle bending vertexes bent at the obtuse angle and the acute angle bending vertexes bent at the acute angle are crossed to form repetitive starry cells having a flexible bending characteristic thereby preventing the stent from folding even when the stent is bent sharply.
