Provided is an indwelling object delivery system which allows high-accuracy positioning of an indwelling object relative to the indwelling object delivery system, enables highly accurate placement in a target position, and effectively suppresses displacement and dislodgement of the indwelling object from the indwelling object delivery system during conveyance. This indwelling object delivery system (10) is provided with: a longitudinally extending shaft (20); a cylindrical stent (70) which comprises recesses (72, 73) formed receding axially at the end on at least one side in the axial direction, and which can be left indwelling in the body, arranged so as to surround the exterior of the shaft (20) in the radial direction at the leading end; and at least one contrast marker (81, 82) having imaging contrast characteristics. The contrast markers (81, 82) are arranged on the outer surface on the leading end of the shaft (20), are arranged corresponding to the leading end and the trailing end of the stent (70) in the axial direction, and comprise projections (81A) which are received in the recesses (72, 73) of the stent (70). |
