Abstract
A radiopaque marker bead can be attached to an endoprosthesis by pressing an end of bead into a through hole formed into the endoprosthesis and allowing the opposite end of the bead to pass through the hole and protrude out of the other end of the hole. Both ends of the bead can then be pressed and flattened so as to frictionally engage both ends of the hole. A support tool having a curved outer surface can be inserted into the endoprosthesis to support the endoprosthesis luminal surface while the bead is being pushed into the hole. The support tool has a depression which allows the opposite end of the bead to protrude out of the hole.
