Aneurysm is a weak spot in a blood vessel that can burst and cause bleeding in the brain. The ELEVATE study is checking if a special tool, the Pipeline™ Flex Embolization Device, can safely fix these bursts when other methods don't work. This study is for adults aged 22-80 who have a specific type of burst in their brain, called an intracranial aneurysm. This means the aneurysm is inside the skull. To join, you should not have certain health issues or be pregnant. You will need to agree to follow-up visits for check-ups. The device is inserted through the blood vessels, so no big surgery is needed.

• The study checks if the device works well and is safe.
• Participants must fit the criteria and give consent.
• Regular check-ups are needed after treatment.

Note: This study might not be right for everyone, especially if other health problems are present. Always discuss with a doctor before joining any study.
