TriVascular Ovation®: its role in solving current endograft deficiencies

Endovascular aneurysm repair (EVAR) techniques and technologies have rapidly advanced over the last two decades. The basic premise of EVAR is to durably exclude flow from the aneurysmal sac without exerting untoward effects on the non-diseased anatomy by using minimally invasive surgical techniques. However, these fundamental components have not yet been perfected with traditional stent grafts and remain important areas for further EVAR refinement. Latest-generation stent grafts are in development to accommodate these therapeutic goals. The Ovation Prime endograft was specifically developed to address the main limitations of EVAR today by expanding EVAR eligibility, allowing least invasive treatment protocols, and protecting the proximal neck from dilatation over the long term. The purpose of this paper was to detail the primary deficiencies typically encountered with EVAR and to describe how the Ovation Prime (R) endograft overcomes these limitations.
