Computational analysis is being used in an innovative way to study and show the behavior of the stent graft in a simulated pulsatile aorta.
Medtronic has been partnering with Thornton Tomasetti, an independent global leader in performance and design evaluation, to further our understanding of stent grafts performance in a dynamic environment.
