Stents which are inserted into a body lumen preferably are made of materials which are not radiopaque enough, such as S.S. 316L. X-ray visualization of a stent enables an accurate positioning of the stent and also a follow-up of its functioning within the patient's body. The radiopaque markers described here are rivets made of a material which is more radiopaque than the stent substance so the location of the stent can be identified. |
