Abstract
A stent delivery system includes: a distal-side tube; a proximal-side tube; a tubular member which contains a stent; a wire which has one end fixed to the tubular member; and an operating section which has a wire winding mechanism and a wire winding amount restriction mechanism for restricting the length of wire which is pulled. The operating section has an operating rotary roller; a winding shaft section and driving gear which are provided coaxially and integrally with the roller; and a driven gear which is intermittently rotated by the driving gear. The driving gear and the driven gear have the stopper function by which rotation of the driving gear is stopped after the driving gear is rotated a predetermined amount.
