ABSTRACT:
A stent delivery device includes a distal-side tube having a guide wire lumen; a proximal-side tube whose distal portion is fixed to a proximal portion of the distal-side tube; a cylindrical member which encloses a distal side of the distal-side tube and is slidable toward a proximal end of the distal-side tube; a stent accommodated in the cylindrical member; and a pulling member6for moving the cylindrical member toward a proximal side of the stent delivery device. The distal-side tube has a proximal-side opening which is open at the proximal side of the distal-side tube; and a stent-locking portion for preventing the stent from moving to the proximal side of the stent delivery device. The outer diameter of the proximal-side tube is set smaller than that of a portion, having a maximum diameter, which is disposed in a region of the stent delivery device which is distal from the proximal-side tube.
