Radiant™ Balloon-Expandable Covered Stent

The only covered stent indicated for ChEVAR, Radiant stent is used in combination with the Endurant™ II/IIs stent graft system to safely and effectively lengthen aortic proximal sealing zones in juxtarenal aortic abdominal aneurysms (jAAA).  


Product details

Indicated. Tested. Proven. Safe and effective in ChEVAR.

  • The only covered stent tested and approved for ChEVAR indication with the Endurant II/IIs stent graft system.
  • Radiant covered stent shows significantly better performance in ChEVAR compared to other stent grafts, with 94.6% patency at mid-term follow-up.1
  • EnChEVAR with Endurant II/IIs system + Radiant covered stent demonstrates durable clinical outcomes.2

Predictable, accurate delivery and deployment.

  • Radiopaque markers ensure accurate placement of stent graft during deployment.
  • Radiant stent's open-cell stent design provides flexibility in delivery and placement.
  • Designed to track through torturous arteries and flex to accommodate the renal anatomy.
  • Low profile offers versatility and effective delivery in complex endovascular procedures.

Designed for radial strength and versatility.

  • Radial strength of the stent design maintains vessel patency in ChEVAR.
  • Designed to bend to accommodate and fit the renal anatomy during use with Endurant II/IIs system in ChEVAR.
  • Ability to post-dilate allows a customized solution to various anatomy.
  1. Full stent encapsulation with PTFE material offers an effective barrier to neointimal hyperplasia.
  2. Open-cell stent design provides flexibility in delivery and placement.
  3. Gold radiopaque marker.
  4. Radiopaque markers ensure accurate placement of stent during deployment.
  5. Radial strength of stent design maintains vessel patency.
  6. No FEP (fluorinated ethylene propylene) adhesive for uniform deployment without delamination.
