PROBLEM TO BE SOLVED: To provide a stent which can suppress a deformation amount in a radial direction with respect to a torsion load.SOLUTION: The stent includes: wavy-line shaped pattern bodies 13 arranged in an axial direction LD; and plural coil-shaped elements 15 arranged between the adjacent wavy-line shaped pattern bodies 13 and extended in a spiral shape around an axis. In a view in a radial direction RD, an annular direction CD of the wavy-line shaped pattern body 13 is inclined with respect to the radial direction RD. The wavy-line shaped pattern body 13 is formed by wave shaped elements 17 connecting two leg parts 17a at an apex part 17b, having a general V-shape, and being connected plurally in a circumferential direction. The apex 17b of the wave shaped element 17 having the general V-shape is positioned between edges 171c, 172c on an opposite side to the apex 17b in the two leg parts 17a in the axial direction LD. A winding direction of one coil-shaped element 15 (15R) positioned on one side in the axial direction LD with respect to the wavy-line shaped pattern body 13 is reverse to a winding direction of the other coil-shaped element 15 (15L) positioned on the other side in the axial direction LD.SELECTED DRAWING: Figure 4 |
