New coils aim to seal brain aneurysms safely
NCT ID NCT03642821
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looked at how safe and effective the OPTIMA coil system is for treating brain aneurysms. Researchers followed 300 patients across Europe for up to 12 months after the coiling procedure. They tracked complications like bleeding, blood clots, and the need for repeat treatment, as well as patients' overall health outcomes.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
OPTIMA coils (a device used to fill brain aneurysms from inside the blood vessel)
What this could lead to
If successful, this could confirm that the OPTIMA coil system is a safe and effective option for treating brain aneurysms, reducing the risk of rupture or rebleeding.
What could go wrong
This was an observational study without a comparison group, so it cannot prove the coils are better than other treatments. Risks include blood clots, bleeding, or the need for retreatment.
