Study Purpose: This study looks at how well a medical device called NeVa VS works to widen narrow blood vessels in the brain. This problem is called cerebral vasospasm, which can happen after a type of bleeding in the brain known as aneurysmal subarachnoid hemorrhage (aSAH).
Who Can Join: Adults aged 22 and older who have symptoms of cerebral vasospasm after aSAH in certain brain arteries can join. They must have already had a procedure using the NeVa VS device. Participants or their legal representatives must agree to join the study within 3 days after the procedure.
- **Procedure:** Involves using the NeVa VS device to help widen narrowed brain arteries.
- **Visits:** Participants are observed over time to assess the device’s effectiveness.
- **Risks:** There are no specific exclusions, meaning anyone meeting the criteria can participate.
This study is important for understanding how effective the NeVa VS device is in treating cerebral vasospasm after bleeding in the brain. Participants help advance medical knowledge and may benefit from careful monitoring and care.
