INDICATIONS

The Valiant Navion thoracic stent graft system is indicated for the endovascular repair of all lesions of the descending thoracic aorta (DTA) in patients having the appropriate anatomy including:

  • Iliac or femoral artery access vessel morphology that is compatible with vascular access techniques, devices, or accessories;
  • Nonaneurysmal aortic diameter in the range of:
    – 16 mm to 42 mm for fusiform and saccular aneurysms/penetrating ulcers
    – 16 mm to 44 mm for blunt traumatic aortic injuries
    – 19 mm to 45 mm for dissections;
  • Proximal landing zone (nonaneurysmal aortic proximal neck length for fusiform and saccular aneurysms/penetrating ulcers or nondissected length of aorta proximal to the primary entry tear for blunt traumatic aortic injuries and dissections) of:
    – ≥ 20 mm for FreeFlo configuration
    – ≥ 25 mm for CoveredSeal configuration; and
  • Nonaneurysmal aortic distal neck length ≥ 20 mm for FreeFlo and CoveredSeal configurations for fusiform and saccular aneurysms/penetrating ulcers.

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

 

Navion W-Stent

W-Stent & FreeFlo Support Stent
The proximal FreeFlo support stent & CoveredSeal
W-Stent evenly distribute radial force over multiple apices and prevent graft in-folding for optimal seal.

Navion marker

Visible Markers
The stent graft’s spherical platinum iridium markers provide high visibility.
