<p>Disclosed is a stent which is mainly configured from a tubular member which forms a meshed tube having flexibility and elasticity, and a plurality of ring members which are arranged separated from one another in positions further inward than both end sections in the central axial direction of the tubular member. The tubular member is configured so that the vertical and horizontal linear sections which form the mesh of said tubular member are formed so as to all three-dimensionally intersect at a substantially equal angle in the central axial direction, and so that the flexible ring members which have a folding and bending restoring elastic force are attached further inward than both end opening sections in the central axial direction of the tubular member. Thus, the disclosed self-expanding stent can be applied to hollow organs such as those with weak inner walls or blood vessels which curve a great deal, to which conventional stents could not be applied due to problems such as durability, and the hardness of the end sections.</p> |
