PURPOSE
To assess numerically the flexibility and mechanical stresses undergone by stents and fabric of currently manufactured stent-grafts.
METHODS
Eight marketed stent-graft limbs (Aorfix, Anaconda, Endurant, Excluder, Talent, Zenith Flex, Zenith LP, and Zenith Spiral-Z) were modeled using finite element analysis. A numerical benchmark combining bending up to 180° and pressurization at 150 ...
