Radiant™ Balloon-Expandable Covered Stent
For chimney endovascular aneurysm repair (ChEVAR)
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).
Overview
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.
- Full stent encapsulation with PTFE material offers an effective barrier to neointimal hyperplasia.
- Open-cell stent design provides flexibility in delivery and placement.
- Gold radiopaque marker.
- Radiopaque markers ensure accurate placement of stent during deployment.
- Radial strength of stent design maintains vessel patency.
- No FEP (fluorinated ethylene propylene) adhesive for uniform deployment without delamination.
