Patient Specific Device for Treating Abdominal Aortic Aneurysms
  • Patient Specific Device for Treating Abdominal Aortic Aneurysms

    This research project stemmed from an NSF CAREER award focused on the development of a novel endovascular device for treating abdominal aortic aneurysms (AAAs). AAA is the gradual weakening and dilation of the infrarenal aorta that can lead to vessel rupture - an catastrophic event. Endovascular stent graft repair (EVAR) for treating AAA were introduced in the early 1990s and serve as an attractive minimally invasive treatment option for patients with AAA. Unfortunately, it is not uncommon that complex aortic anatomy leads to the ineligibility of a significant portion of the AAA patient population for EVAR. Our research team has developed a prototype endovascular treatment that is designed directly from the patients unique aortic anatomy. Our hypothesis is that our design will not only make EVAR available to those AAA patients with complex anatomical disease, but also reduce the incidence of graft instability following treatment (e.g., device migration and endoleak).
