Summary

This study is testing a new device called the Choydar flow-directed mesh stent to treat unruptured brain aneurysms — weak spots in blood vessels that could burst. About 200 people will receive the stent, which is placed inside the artery to block blood flow into the aneurysm and prevent rupture. Researchers will check how well the stent works and monitor for complications like stroke or re-treatment over 12 months.
