Mesh tube could seal dangerous brain aneurysms without surgery

NCT ID NCT04195568

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a device called the Surpass Evolve Flow Diverter, a small mesh tube placed inside an artery to redirect blood flow away from a brain aneurysm. The goal is to safely close the aneurysm and prevent it from rupturing. About 248 adults with unruptured, wide-neck aneurysms up to 12 mm in size are being followed for 12 months to see if the device works and is safe.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Surpass Evolve Flow Diverter System (a mesh tube placed in the artery to redirect blood flow away from the aneurysm)

What this could lead to

If successful, this device could offer a safer, less invasive way to treat wide-neck brain aneurysms, potentially reducing the need for open surgery or lifelong medication.

What could go wrong

This is a single-arm study without a comparison group, so results may not prove superiority over existing treatments. Risks include stroke, incomplete aneurysm closure, or device-related complications.
