次世代医療に向けた弁付ハイブリッドフラクタルステントの研究

―CFDによる脳動脈瘤内の血流シミュレーション―

We proposed a valved hybrid fractal stent to treat the unruptured cerebral aneurysm. Stenting and coil embolization can be used together by the stent. The stent has a valve part to coil insertion hole. The valves have fractal structures. So, the blood velocity into cerebral aneurysm is decreased. We have carried out the aneurysm in the blood circulation simulation by stent pattern by using a Computational Fluid Dynamics (CFD). Five fractal patterns have verified whether to have a flow-diverter effect.
