Select the Valiant Navion^™ thoracic stent graft system for your thoracic endovascular aortic repair (TEVAR) procedures. The low-profile delivery system with FreeFlo and CoveredSeal proximal stent graft options are designed for versatility, uncompromising conformability, control, and accuracy. The reimagined design offers enhanced vascular access with a broad set of options to treat a wide range of patient anatomies. The reimagined design, built on proven platforms, offers enhanced vascular access with:

Indications

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 blunt traumatic aortic injuries (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 pre-existing risk factors.

PRODUCT DETAILS

Features

The Valiant Navion™ system is built on our decades of thoracic and abdominal stent graft experience. The Valiant Navion stent graft system has a versatile low-profile design that has optimized flexibility and conformability to adapt to individual patient anatomy and ensures accurate placement.

Low-Profile, Versatile Design

• FreeFlo configuration with tip capture provides uncompromised control and enhanced conformability for precise accurate placement
• CoveredSeal configuration with tip capture is a true covered stent that provides uncompromised control and conformability for precise accurate placement

Optimized Access

• Low profile: 18-22 Fr O.D. crossing profile for enhanced vascular access
• Hydrophilic coating facilitates stent graft delivery
• Easy three-step deployment process

Conformability

• Multi-filament thoracic graft material based on the Endurant™ AAA stent graft yarn and designed for increased flexibility and superior permeability resistance
• Sinusoidal shape and placement of nitinol springs provide flexibility and conformability
• Super-elastic nitinol springs exert active radial force to enhance seal and conformability

Accuracy

• 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 proximal stents for both FreeFlo and CoveredSeal configurations

Delivery and Deployment

The Valiant Navion™ delivery system supports control and accurate placement of the stent graft at every step of deployment across a range of anatomies.
