摘要： A guide extension catheter including a distal shaft and a proximal shaft, wherein: a main body of the distal shaft is placed on a support base of a three-point bending test jig where a distance between fulcrums is 15 mm; an indenter that approaches the support base at a speed of 10 mm/min in a middle between the fulcrums is pressed against the main body from a lateral side to deform the main body until kinking occurs; and at that time, a maximum load value acting on the main body is 0.1 to 0.6 N. A distal end tip that is more flexible than the main body is provided to the distal shaft. The distal end tip has a length dimension of 2.5 mm or greater, and includes a marker part mixed with a powder made of a radiopaque material.
