Abstract

A stent indwelling device includes a guide catheter and a pusher catheter. The guide catheter includes: a core section; an outer layer section surrounding an outer circumference of the core section; a stent protection section disposed between the core section and the outer layer section, being longer than a dimension of a tube stent, having stiffness resisting compression inward in a radial direction perpendicular to a longitudinal axis of the guide catheter, and having flexibility in a direction in which the guide catheter is curved; and a stopper configured to allow expansion of the stent protection section in a direction along the longitudinal axis and restrict movement of the stent protection section in the direction with respect to the core section.
