Summary

This study is testing a new device called the Choydar flow-directed mesh stent for people with unruptured brain aneurysms (a bulging blood vessel that could burst). The stent is placed inside the artery to block blood flow into the aneurysm, reducing the risk of rupture. About 200 participants will be followed for 12 months to see how well the stent works and if it causes any serious side effects like stroke or bleeding.
