Discover Continuous Seal

in a dynamic environment with Valiant™ Captivia™ stent graft​ system

Learn more

The thoracic aorta is highly elastic and flexible1, it adapts to the hemodynamics2 creating a dynamic environment. Discover how maintaining a continuous seal in the proximal seal zone of a stent graft over the cardiac cycle improves durability in TEVAR3.
