Coil treatment may offer brain bleed patients a Surgery-Free option
NCT ID NCT07197840
First seen Nov 01, 2025 · Last updated Jun 23, 2026 · Updated 27 times
Summary
This study tests a device called the Numen SILK coil, which is placed into the middle meningeal artery to block blood flow and help resolve chronic subdural hematoma—a slow brain bleed common in older adults. Researchers will enroll 100 people to see if this minimally invasive procedure reduces the need for rescue surgery or death within 180 days. The goal is to offer a less risky alternative to traditional brain surgery.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Numen SILK coil embolization system (a device that blocks blood flow in the middle meningeal artery)
What this could lead to
If successful, this minimally invasive coil procedure could become a standard way to treat chronic subdural hematoma, reducing the need for brain surgery and lowering the chance of blood re-accumulation.
What could go wrong
This is a single-arm, post-market study with no comparison group, so results may be less definitive. The procedure carries risks such as bleeding, infection, or coil migration, and it may not work for all patients.
