Abstract
A stent delivery system includes a pusher guide wire for delivering a stent having an anchor member. The pusher guide wire includes a core shaft, a coil body that is disposed around a distal portion of the core shaft and includes a tapered portion having an outer diameter that decreases toward a distal end of the coil body, and a protruded portion fixed to the coil body at a position distal to the tapered portion. The anchor member is positioned between the tapered portion and the protruded portion when the stent is delivered using the pusher guide wire. The anchor member can therefore be pushed in the distal direction by the tapered portion of the coil body. Moreover, the stent can be retracted into the catheter by pulling the pusher guide wire in the proximal direction so that the protruded portion contacts the anchor member.
