The wall has a pattern formed therein with openings extending therethrough into the bore. At least one radiopaque marker is carried by the wall and is disposed in an opening in the wall. The radiopaque marker is comprised of a framework formed in the wall and is disposed in an opening in the wall and lies within the confines of the wall. The framework is isolated from the pattern so that it does not interfere with the expansion of the expandable stent. The framework has an eyelet therein.
