Abstract
A pusher guide wire and a delivery system can smoothly pass through the inside of even a curved blood vessel without causing excessive burden to a stent, a catheter, and the like. A pusher guide wire has a tubular member capable of moving in a radial direction relative to a core shaft of the pusher guide wire. When the pusher guide wire is used together with a stent in a delivery system, the tubular member makes contact with the stent in an appropriate manner when passing through the inside of a curved blood vessel. The stent may include a proximal end engagement portion provided at a proximal end of the stent. When the stent is placed so that the proximal end engagement portion engages with the pusher guide wire, the stent can be pulled back inside the catheter by pulling the pusher guide wire in the proximal direction.
