It has been known for more than a decade that intracranial aneurysms can be successfully treated by deploying a porous meshed tube in the parent vessel of the aneurysm. Such devices are currently called flow diverters because they promote intraneurysmal flow stasis and thrombosis by diverting blood flow away from the aneurysm sac. The objective of this(More)
A) an angiogram showing a large ~25 mm aneurysm on the right internal carotid artery; B) vasculature segmented in SimVascular, lofted in Rhinoceros, and imported into SolidWorks; C) flow diverter stent simulated in Matlab with VMTK input; D) vasculature and stent bodies imported into ADINA for mesh generation. Introduction: A new class of stents called flow(More)
Intracranial aneurysms are abnormal focal enlargements of the vascular walls that require immediate surgical intervention once detected. Emerging stent technology involves an innovative type of finely-braided stents, called flow diverters, which abruptly impede the arterial flow into the aneurysm, upon deployment, and induce thrombosis, vascular remodelling(More)
Many factors that are either blood-, wall-, or hemodynamics-borne have been associated with the initiation, growth, and rupture of intracranial aneurysms. The distribution of cerebral aneurysms around the bifurcations of the circle of Willis has provided the impetus for numerous studies trying to link hemodynamic factors (flow impingement, pressure, and/or(More)
