Abstract:
1. A guide catheter being insertable inside a stent and inside a pusher catheter which pushes the stent, and adapted for being inserted into the interior of a living body with the stent and the pusher catheter by being guided along a guide member inserted inside the guide catheter, the guide catheter comprising: an elongated tubular main body; and an engaging portion formed at a head section of the main body so as to be integrated with the main body and to protrude outward from an outside surface of the main body, wherein, in a state where the guide member is inserted into the main body, the engaging portion is supported by the guide member from the inside thereof, thereby the engaging portion protrudes outward and contacts only a distal end of the stent put on the distal end of the pusher catheter, in a state where the guide member is retracted away from the main body, the engaging portion loses the support by the guide member from the inside of the main body, thereby the engaging portion allows release of the stent from the guide catheter.
