Valiant Navion™ is the third and latest generation of thoracic endovascular aortic repair (TEVAR) in a single system, with covered and bare stent options.
The Valiant Navion system is designed to treat a wide range of patient anatomies and all lesions of the descending thoracic aorta (DTA), including thoracic aortic aneurysms (TAA), type B aortic dissection (TBAD), intramural hematoma (IMH), penetrating atherosclerotic ulcer (PAU), and blunt thoracic aortic injury (BTAI).
With Valiant Navion, you can confidently treat even more patients.

The Valiant Navion delivery system supports controlled and accurate placement of the thoracic stent graft at every step of deployment across a range of descending thoracic aorta anatomies and diseases.
Features of the Valiant Navion delivery system:
Tip capture provides controlled deployment and precise placement in the thoracic aorta for both FreeFlo and CoveredSeal configurations.
Tip capture release handle provides simple turn-and-pull motion to release the proximal stents for both FreeFlo and CoveredSeal configurations.
The Valiant Navion thoracic stent graft system offers more sizing options, including tapered grafts, to treat a wide range of anatomies.
The Valiant Navion system — with CoveredSeal (no proximal bare metal) and FreeFlo proximal designs — enables you to confidently treat even more patients.
Dr. Ross Milner discusses how he expands TEVAR treatment to more of his patients.
Valiant Navion FreeFlo, with proximal bare stent, is designed for perfusion into proximal vessels.
Valiant Navion CoveredSeal, with completely covered proximal edge, is tailored for fragile aortas with no bare metal interaction with the aorta.
Designed in the Medtronic Nitinol Center of Excellence, the proximal FreeFlo support stent and CoveredSeal W-stent (pictured) evenly distribute radial force over multiple apices and prevent graft infolding.

Partially uncovered bare metal stents
Fully exposed bare metal stents
Stainless steel stent graft
The Valiant Navion thoracic stent graft system is indicated for treatment of diseases of the descending thoracic aorta, including but not limited to, aneurysms, dissections, and BTAIs. The Valiant Navion thoracic stent graft is indicated for exclusion of the aneurysm, the false lumen, or site of rupture, and the restoration of blood flow through the stent graft lumen. The device is intended for use in patients who are candidates for conventional surgical repair, and in patients who are not candidates for conventional surgical repair due to preexisting risk factors.
