    • PROBLEM TO BE SOLVED: To provide a stent device that fulfils the desires of a suitable rigidity to radial pressure and suitably high bending flexibility even when many consecutive stents are interconnected, and further, to provide a stent device that has a smaller tendency towards migration in vessel over a long period following implantation than the prior-art devices.
      SOLUTION: The stent device includes a tubular graft and at least one tubular member, which is extended in a longitudinal direction and has several longitudinally consecutive cylindrical spring members 4 interconnected by connecting members 5. The connecting members 5 have a length keeping the cylindrical spring members 4 at a mutual distance when the tubular member is in its uncompressed state with the larger diameter. The tubular graft material has annular bellows folds in the areas between the spring members. The tubular graft material in the tubular member is deformable in the longitudinal direction of the tubular member.
