A stent delivery system includes an inner tube having a guide wire lumen formed therein, through which a guide wire is inserted, an outer tube including a lumen, through which the inner tube is inserted, and arranged to be relatively movable with respect to the inner tube, a distal member fixed to a distal end of the inner tube, and a stent arranged between a distal portion of the inner tube and a distal portion of the outer tube and configured to expand and deform after being released from between the inner tube and the outer tube along with movement of the outer tube. With the stent released, the inner tube and the distal member are configured to be removable from the outer tube via the lumen of the outer tube.
