PROBLEM TO BE SOLVED: To provide a stent delivery device, even when a pipe member of an inner tube proximal side is narrowed, inhibiting deformation and kink thereof.SOLUTION: A stent delivery device 10 includes an outer sheath 20 having a handle 30 at a proximal side, and an inner tube 40, and is configured to open a stent 1 by sliding the outer sheath 20 to the proximal side with respect to the inner tube. The stent delivery device includes: a pipe member 50 connected to a proximal side of the inner tube 40 and drawn out from a handle base-end-side opening; a hub 60 connected to a pipe member proximal end; and a guard member 70 that surrounds the outer periphery of the pipe member 50, in which one end is fixed to the base end of the handle 30, and the other end is fixed to the hub 60, and that is stretchable with variation in distance between the handle 30 and the nub 60.SELECTED DRAWING: Figure 1 |
