Continuous Proximal Seal in a dynamic environment
To address durability, it is important to maintain the continuous seal. 1, 2
Alert Indications, Safety, and Warnings
Short and long-term outcomes are fostered by stent graft design elements.
Discover how we are investigating the behaviour of Endurant™ stent graft in a dynamic environment, with computational analysis.

The 2024 latest ESVS guidelines underline the importance of a long-term clinical follow-up.3
"Understanding the dynamic behavior of the endograft and the aortic wall using computational models will allow to optimize patient care through informed and personalized device selection."
Dr. Marco Virgilio Usai

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.
