<p>Provided is a stent in which a wire (W) is circumferentially and axially advanced while being bent in a wave shape, and bent portions of the wave shape form engaging portions so as to create a tubular mesh pattern. The stent has a developed mesh pattern in which alternately arranged are: a first mesh connected portion (10C) in which a plurality of substantially parallelogram-shaped first meshes (10) having the engaging portions as vertexes are connected while sharing short sides of the parallelogram; and a second mesh connected portion (20C) in which a plurality of substantially trapezoid-shaped second meshes (20) having the engaging portions as vertexes are connected while sharing legs of adjacent trapezoids on bases thereof, the second meshes (20) sharing long sides of the parallelogram which is the shape of the first mesh (10) as the bases thereof. No more than three of the engaging portions are formed in the same axial direction position. According to this stent, the diameter thereof can be sufficiently reduced without the plurality of engaging portions overlapping each other when inserting into a sheath.</p> |
