Summary
This study tests a new device called SEAL™ that is placed inside a brain aneurysm to block blood flow and prevent rupture. About 279 adults with unruptured or recently ruptured aneurysms are taking part. The goal is to see if the device safely and effectively seals the aneurysm within 12 months.

What this could lead to
If successful, this device could offer a safer, more effective way to treat brain aneurysms and reduce the need for repeat procedures.
