Abstract
A pusher guide wire for delivering a stent to a target site includes a core shaft, a coil body that covers a distal end portion of the core shaft, a pusher portion that is fixed to the core shaft at a position proximal to the coil body, and a stent holding portion that is fixed to the core shaft at a position between the coil body and the pusher portion. In the pusher guide wire, frictional resistance between the stent and the stent holding portion is larger at a proximal end portion of the stent holding portion than at a distal end portion of the stent holding portion.

A pusher guide wire for delivering a stent to a target site, the pusher guide wire comprising:
- a core shaft;
- a first coil body that covers a distal end portion of the core shaft;
- a pusher portion that is fixed to the core shaft at a position proximal to the first coil body;
- and
- a stent holding portion that is fixed to the core shaft at a position between the first coil body and the pusher portion,
- wherein frictional resistance between the stent and the stent holding portion is larger at a proximal end portion of the stent holding portion than at a distal end portion of the stent holding portion.
