S021021 Study on development of stent using optimization to stent strut patternr

Abstract

Stent implantation in intracranial arteries is termed as endovascular treatment. The number of such cases has been increasing worldwide because the surgical damage resulting from stenting seem to be less than that of other treatments. A side wall type idealized aneurysm shape reconstructed by straight pipe and half sphere were used, Z-type stent was used. CFD analysis was performed each aspect ratio aneurysm and stent strut pattern. The optimization by the process of Multi-Objective Genetic Algorithm and Kriging was performed to the CFD results From the results, we report the development of new stent strut pattern in cerebral aneurysm using the computational fluid dynamics (CFD) and optimization.
