PROBLEM TO BE SOLVED: To provide an in-vivo indwelling stent which has sufficient flexibility, has few points of change as a whole stent, and has good curvature after being indwelled. SOLUTION: A stent 1 is formed in a substantially cylindrical shape by a linear body, is compressed and reduced in diameter when inserted into a living body, and is restored to a shape before contraction when placed in a living body, and is a zigzag stent. A plurality of linear spiral bodies 21, 22, 23, 24 formed in a spiral by the linear bodies of the structure are parallel to the axial direction of the stent 1 and each linear spiral body 21, 22, 23, 24. The stent body 2 has a configuration in which the stent body 2 is arranged without being connected, and the tubular cover 3 which closes a side surface of the stent body while maintaining the arrangement state of the plurality of linear spiral bodies in the stent body 2. ing. |
