New mesh stent aims to seal brain aneurysms without surgery
NCT ID NCT07228312
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing a new device called the Choydar flow-directed mesh stent for people with unruptured brain aneurysms—weak spots in blood vessels that could burst. The stent is placed inside the artery to block blood flow into the aneurysm, helping it heal. Researchers will follow 200 participants for 12 months to see how well the stent works and if it causes any serious side effects like stroke or bleeding.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Choydar flow-directed mesh stent
What this could lead to
If successful, this stent could offer a safer, less invasive way to seal brain aneurysms and prevent them from bursting.
What could go wrong
This is an observational study, not a randomized trial, so results may be less definitive. Risks include stroke, bleeding, or stent narrowing.
