Brain Aneurysm Coiling is a procedure used to treat a weak spot in a blood vessel in the brain, called an aneurysm. Using a thin tube (catheter), the doctor gently places a small, soft metal coil inside the aneurysm. This coil helps block blood flow into the weak area, which can stop bleeding if the aneurysm has already ruptured or prevent it from bleeding in the future. The coil is made of soft platinum and is attached to a fine delivery wire for precise placement.
