| Outline of Final Research Achievements |
The final goal of this study is to catch the precursor phenomenon of an accident in intravascular treatment. In this study, the relation between the feature of configuration of wire-like device such as guidewire and catheter, that is used in intravascular treatment, and the behavior of these devices in vessel wall.
We focused on fourier descriptor as a technique to express the feature of configuration of wire-like devices. From numerical simulations, contact force of the tip of guidewire has the strongest relation to the similarity between original configuration of a guidewire and deformed configuration of the guidewire inserted into blood vessel. In experiments, the precision of the numerical simulation was quantitatively evaluated.
