Advanced Devices for Aortic Intervention


PROBLEM: What is an aortic aneurysm? 

An aortic aneurysm is the bulging of the aorta, causing a risk of rupture at that location. It has ranked within the 15 leading causes of death for both sexes above the age of 60 in the United States since 1999, except in 2012 [1], and its occurrence is expected to increase with global population ageing. Post-rupture survival rates are as low as 10 to 20% [2].


SOLUTION: Endovascular Stent Grafts

To prevent rupture, patients with aortic aneurysms can be treated with a minimally invasive surgical procedure called endovascular aneurysm repair. An endovascular stent graft is inserted to exclude the aneurysmal sac from blood flow.



The ARC Research Hub for Advanced Manufacturing of Medical Devices is endeavouring to make the production of devices like the endovascular stent graft better, faster and more efficient.
