Stent and method for manufacturing the same

Abstract

A method of manufacturing a stent includes forming a first cylindrical mesh structure by bending a first member in a zigzag-shape having peaks and valleys and a plurality of turns wound around an outer circumference of a manufacturing frame and forming a second cylindrical mesh structure by bending a second member in a zigzag-shape having peaks and valleys and a plurality of turns wound around anouter circumference of a manufacturing frame, wherein a bending track the second member crosses a bending track of the first member.

Description

technical field [0001] The present invention relates to a stent and a method for making the stent, and more particularly to a stent and a method for making the stent by preventing its material from being damaged during the manufacturing process. Improve the quality of brackets. Background technique [0002] Generally, a stent may be inserted into a lesion of a cavity or blood vessel of the body to maintain passage of the cavity or blood vessel. The stent may be formed from a shape memory alloy (eg, Nitinol) that maintains a uniform expansion force at the temperature of the lumen. The stent may be formed in a cylindrical shape braided with wires, and the cylindrical stent may be formed by sequentially and repeatedly braiding two thin and long members to have better expansion force (elasticity) in the radial direction. That is, a plurality of nails are arranged on a cylindrical manufacturing frame. The distance between the nails is the same as each other. Two thin and long...

Problems solved by technology

Therefore, in the above process, the wire member may be damaged, thereby reducing its elastic force and thus deteriorating the quality of the product.
