| Research Abstract |
A catheter used by a treatment and a diagnosis of circulatory organ system needs mastery of skills of a operator for the insertion to the body of a patient. This study focused on the point and is aimed for movement in a blood vessel and development of the catheter which can do various operation automatically. This mechanism uses peristaltic movement by the expansion / the shrinkage of a period of plural balloons by pressure filling / removing of a saline. Then, in order to create a detailed design plan, the various experiments for grasping the characteristic of a balloon required to build an expression model are conducted. Moreover, in this study, in order to verify the detailed mechanism at the time of a run, an expression model is built as an equation of motion. From these results, a simulation is performed using numerical analysis software.
