The study of valved hybrid fractal stent for the next generation medical care

- The blood flow simulation in cerebral aneurysm by CFD. -

Abstract

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.
