Clinical Outcomes Endurant™ II Stent Graft Systems

The Endurant family of products provides the standard of care with a legacy of clinical success for the treatment of abdominal aortic aneurysm (AAA). Only the Endurant family of products, designed to address sac regression,1 has the deep clinical experience, favorable outcomes, and the most validated data on any single graft for everyday or extraordinary challenges. For the past five years, the Endurant II/IIs has been used in 1 out of 3 EVAR cases,1 with use in more than 450,000 patients worldwide.1
