Summary

This study tested a new medical device called the Tonbridge flow diverter to treat brain aneurysms (weak spots in blood vessels). The device is placed inside the artery to redirect blood flow away from the aneurysm, helping it heal. The trial included 142 people aged 18 to 80 with unruptured aneurysms in specific brain arteries. The main goal was to see if the aneurysm was completely blocked at 12 months after the procedure.
