As the material of recent catheter, which is used in the operation such as the myocardium infarction, not only a soft characteristic but also the responsiveness and the operationally are required in order to carry out the remote operation smoothly. The purpose of this study is to investigate the deformational behavior and strength of catheter, which is made from the nylon resin braided by a thin stainless wire. In this paper, we propose the analytical model in consideration of the geometric relation of a braid and we decide Young's modulus. And, the validity of this model is confirmed by comparing numerical results with experimental results. Furthermore, performing numerical simulations with various braid angles, we investigate a viscoelastic response of the catheter under uni-axial tension.
