Treatment with Endovascular Stents
Stent configurations in bifurcating aneurysms:
Using both PIV and computational fluid dynamics (CFD) we have quantified the performance of different stent configurations on aneurysmal fluid dynamics

A common treatment for wide-neck cerebral aneurysms is multiple stent-in-stent deployments that reduce stent porosity and enhance flow diversion. We have conducted in-vitro studies to quantify the changes in aneurysmal fluid dynamics using these techniques.
Stand-alone Stent treatment
In collaboration with the Center for Advanced Surgical and Interventional Technolgy at UCLA, we are investigating the fluid dynamic performance of a Hyper-Elastic Thin Film Nitinol (HE-TFN) covered stent for stand-alone stent treatment.
