Abstract
A method of manufacturing a stent delivery system and a stent delivery system that can reduce an insertion resistance of an outer tube relative to an inner wall surface of another medical appliance, such as a catheter. The method includes: deforming, by disposing an insertion member in a lumen of the inner-side tube, opposing two locations of the inner-side tube; disposing the respective operation wires in the pair on outer peripheral sides of the opposing two locations of the inner-side tube; disposing the outer-side tube at an outer peripheral side of the inner-side tube so as to surround the inner-side tube and the pair of the operation wires; and disposing, in a state where an insertion member is disposed in the lumen of the inner-side tube, a retaining member that retains a cross-sectional shape of the inner-side tube in a space formed between the inner-side tube and the outer-side tube.
