The purpose of this study is to clarify the creep deformation behaviors of a catheter made of nylon resin and stainless steel wires. In the previous studies, the creep deformation behaviors under step proportional loads have been investigated by changing the ratio of tension and torsion under hydrous conditions. Under hydrous conditions, it is considered that Young's modulus of the matrix will decrease and the braids made of the stainless steel wires will peel off. In addition, the loading histories for tension and torsion are closely related to the creep deformation behaviors. In this report, the experiments of creep deformation behaviors obtained under the three-step loading for tension and torsion are conducted under hydrous conditions, and these experimental results that the first stage is tensile load are compared with anhydrous conditions.
