<p>PROBLEM TO BE SOLVED: To provide a tube stent delivery device facilitating adjustment of a position of a tube stent, eliminating entanglement of a thread and a string in a body, and reliably placing a tube stent at an accurate position in the body.SOLUTION: An intermediate stopper 24 that has an outside diameter larger than an inside diameter D12a of a distal end opening 12a of a tube stent 10 is formed at a prescribed position in a proximal end side from the distal end of an inner catheter 20. The intermediate stopper 24 includes a main small-diameter part 26 formed at a proximal end side thereof, the main small-diameter part having an outside diameter D5 smaller than the inside diameter D12a of the distal end opening 12a of the tube stent 10. The main small-diameter part 26 includes a base-part large-diameter part 28 formed at the proximal end side thereof, the base-part large-diameter part having the outside diameter larger than the outside diameter D5 of the main small-diameter part 26. The inner catheter 20 is axially moved relative to an outer catheter 40 to the proximal end side such that the intermediate stopper 24 of the inner catheter 20 can be inserted into a through-hole 12c of the tube stent 10.</p> |
