Disclosed is a stent delivery system (1) which includes a body and an operation unit (6) disposed at an proximal end of the body. The body includes a self-expanding stent (10), an inner tube body (3), and a stent-accommodating tube body (5) in which the stent (10) is accommodated. The inner tube body (3) has a stent-holding part enabling the stent (10) to be re-accommodated into the stent-accommodating tube body (5). The operation unit (6) includes: a rack member (43) which is fixed to a proximal end of the stent-accommodating tube body; an operation rotary roller (50) which has a working gear wheel (54) that engages with teeth (66) of the rack member (43), thereby causing the rack member to move forward and backward; and a connector (46) which is fixed to a proximal end portion of a proximal-side tube (34) that penetrates the stent-accommodating tube body and protrudes from the proximal end of the stent-accommodating tube body. |
