As a material of the catheter, a soft characteristic is required so as not to damage the urethra and the vessel wall. On the other hand, in the surgical operation such as the myocardial infarction and the cerebral infarction, not only a soft characteristic but also the responsiveness and enough rigidity are required so as to satisfy the excellent operability. Moreover, the relatively long catheters are often used in the actual operation and an unstable phenomenon such as buckling occurs easily in spite of small axial compressive load. In this paper, the snap-through behavior, which occurs under initial torsion, is investigated by performing the experiments with various initial twisting angles.
