The present invention relates to a flexible stent. The flexible stent comprises: a first hollow unit having a plurality of peaks and valleys formed by winding a first wire in a zigzag manner along a plurality of fixing pins arranged in a cylindrical stent manufacturing jig, the first hollow unit forming a cylindrical structure; and a second hollow unit formed by winding a second wire along the fixing pins from among the plurality of fixing pins not wound by the first wire, the second wire intersecting the first wire and forming a separate cylindrical structure along an outer circumferential surface of the first hollow unit. The present invention provides stent technology in which a plurality of peaks and valleys that constitute the first hollow unit are interposed between the plurality of peaks and valleys constituting the second hollow unit in such a manner that the first wire constituting the first hollow unit is prevented from protruding from the second hollow unit in the event that the shape of the first hollow unit is deformed. Therefore, the stent of the present invention may maintain a curved state to fit the shape of the curved body part undergoing surgery and may provide convenience in carrying out a surgical procedure. |
