A sheath ( thin tube ) is then placed in the artery , which provides continual access to the artery . Using X-ray visualization and high-speed filming techniques that provide a continuous view of the normal blood vessels and aneurysm , the doctor inserts a catheter , led by a guide wire , and advances it to the site of the aneurysm . Through the catheter , a smaller microcatheter is advanced into the aneurysm opening and the coil system is introduced .
The coil system consists of different materials , most commonly platinum and sometimes other gel-like and suture-like materials . The coils are soft and pliable , and are available in several sizes and shapes to fit correctly inside an aneurysm .
While inside the catheter , the coil is straight , but when the coil exits the catheter , it takes on a spiral shape , conforming to the shape of the aneurysm . The coil ( or coils , as sometimes more than one is needed ) prevents blood from flowing into the aneurysm . This causes the blood inside the aneurysm to clot , which destroys the aneurysm .
