New device aims to seal aortic aneurysms without open surgery
NCT ID NCT02996396
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study followed 48 people who received the Nellix system, a device that seals abdominal aortic aneurysms from the inside using stents and polymer-filled bags. Researchers tracked how well the device worked right after the procedure and for up to 5 years. The goal was to see if the device could prevent rupture and avoid major complications.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Nellix Endovascular Aneurysm Sealing System (a device with stents and polymer-filled bags to seal the aneurysm)
- What this could lead to
- If successful, this registry could confirm that the Nellix system is a safe and effective way to seal abdominal aortic aneurysms without open surgery.
- What could go wrong
- This is a small, single-arm observational study with only 48 patients, so results may not apply to everyone. The device may still fail to prevent rupture or require additional procedures.
