Abstract

The present invention provides a cylindrical surgical stent which is not contracted in an axial direction even during expansion. The invention comprises a ring-shaped stent ring having: a plurality of cells arranged by being spaced in a row in a circumferential direction; and a plurality of first links. The plurality of cells include first curved portions which are convex in a circumferential direction, second curved portions which are concave in a circumferential direction, third curved portions which are convex in an axial direction, and fourth curved portions which are concave in an axial direction. Said first curved portions are respectively connected with the third curved portions and the fourth curved portions, and said second curved portions are respectively connected with the third curved portions and the fourth curved portions. Said first links are formed from a plurality of links, which connect first curved portions and second curved portions of two adjacent cells among the plurality of cells, and have fifth curved portions that are convex in an axial direction. Spots at which the first curved portions and the second curved portions meet the plurality of first links are out of the central axes of the first curved portions and the second curved portions.
