Coiling is a minimally invasive procedure to permanently prevent an aneurysm from rupturing. Coiling does not require open surgery. Instead, a catheter is inserted into the femoral artery in the leg and navigating to the aneurysm in the head. Tiny platinum coils are threaded through the catheter and into the aneurysm until the aneurysm is completely filled. This blocks blood flow into the aneurysm and prevents it from rupturing. Using platinum allows the coils to be visible on X-ray and flexible enough to conform to the shape of the aneurysm.
