Researchers have modeled the flow of blood through these devices to estimate clotting risk, but this type of work has not been done on stent grafts--until now. The results showed that shear accumulation in a new endovascular stent graft design was comparable to that of an idealized aorta. South Dakota State University and Sanford Health
