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.La présente invention concerne une endoprothèse vasculaire souple. Lendoprothèse vasculaire souple selon linvention comprend : une première unité creuse comportant une pluralité de pics et de vallées formés par enroulement dun premier fil en zigzag le long dune pluralité de broches de fixation agencées dans un élément de montage dendoprothèse vasculaire cylindrique, la première unité creuse formant une structure cylindrique et une seconde unité creuse formée par enroulement dun second fil le long des broches de fixation parmi la pluralité de broches de fixation le long desquelles le premier fil nest pas enroulé, le second fil se croisant avec le premier fil et formant une structure cylindrique séparée le long dune surface circonférentielle ex
