The ovation abdominal stent graft for the treatment of abdominal aortic aneurysms: Current evidence and future perspectives

Abstract

The Ovation Abdominal Stent Graft System is a trimodular endoprosthesis recently introduced for the endovascular repair of abdominal aortic aneurysm (AAA). It uncouples the stages of stent-graft fixation and sealing with the suprarenal fixation achieved with a long, rigid anchored stent while the sealing onto the neck is accomplished via a pair of polymer-filled inflatable rings that accommodate to each patients individual anatomy. Moreover, the lack of Nitinol support enables lower profiles of the endografts delivery system, thus facilitating the navigation through angulated and stenosed iliac vessels. Ovations novel design expands further the AAA eligibility to endovascular repair. This article discusses the clinical and hemodynamic consequences of the Ovation design and contributes to better understanding of current and future implications. © 2016 Taylor & Francis.
