Brain aneurysm coils put to the test in largest Real-World study
NCT ID NCT03642639
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tracked 723 people with brain aneurysms treated using MICRUSFRAME and GALAXY coils, sometimes with a PulseRider device. The goal was to see how well the coils blocked the aneurysm and kept it closed after 12 months. Researchers collected data from real hospital settings to understand the devices' everyday performance.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
MICRUSFRAME and GALAXY coils (medical devices used to block blood flow to an aneurysm)
What this could lead to
If successful, this could confirm that these coils are a safe and effective option for treating brain aneurysms in everyday medical practice.
What could go wrong
This is an observational registry, not a controlled trial, so results may not prove the coils are better than other treatments. Some aneurysms may still reopen over time.
