Numerical analysis of stent porosity and strut geometry for intra-saccular aneurysmal flow
We numerically simulate the hemodynamics of aneurysmal flow and evaluate stent design configuration based on an idealistic geometrical model. We examined large-scale swirling of blood within a significantly dilated aneurysm. Various parameters such as stent porosity and strut shape have an impact on...

| description | We numerically simulate the hemodynamics of aneurysmal flow and evaluate stent design configuration based on an idealistic geometrical model. We examined large-scale swirling of blood within a significantly dilated aneurysm. Various parameters such as stent porosity and strut shape have an impact on the pressure and shear strain rate within the aneurysm. Using biofluid mechanical parameters such as pressure gradient and shear strain rate for aneurysmal arteries implanting with different stent configuration, a flow analysis framework for evaluation of stents is developed. With the application of cardiac flow analysis, we are aim to achieve a balance in the two properties in order to prevent aneurysmal rupture and thrombosis formation and give out the most suitable stent configuration for the stent implanting surgery. © 2011 CCAL. |
