New coil treatment aims to seal brain aneurysms
NCT ID NCT05563051
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a procedure that uses tiny coils to block blood flow in brain aneurysms (bulging blood vessels). The goal is to seal the aneurysm and prevent rupture. About 164 people with aneurysms 4-14mm in size are being followed for one year after treatment.
