The Endurant II AAA Stent Graft System is placed inside the abdominal aorta through catheters inserted into blood vessels in the groin. The device is designed to conform to a broad range of aortic anatomies, empowering physicians to offer endovascular aortic repair (EVAR) to more AAA patients than ever before.

An endovascular stent graft is a tube composed of fabric supported by a metal mesh called a stent. It can be used for a variety of conditions involving the blood vessels, but most commonly to reinforce a weak spot in an artery called an aneurysm.
What is the endurant graft system?
The stent graft system is comprised of 2 main components: the implantable Endurant Stent Graft and the disposable Endurant Delivery System. The stent graft is preloaded into the delivery system and advanced to the aneurysm using fluoroscopic guidance.
What is the difference between a catheter and a stent graft?
Catheters are inserted in the incisions to guide and deliver a stent-graft through the blood vessels to the aneurysm. An endovascular stent graft is a fabric tube supported by metal wire stents (also called a scaffold) that reinforces the weak spot in the aorta.
