Abstract

A temporary bioabsorbable-radiopaque marker for use on an implantable endoprosthesis. The bioabsorbable-radiopaque marker is adapted to be disposed on or adjacent an implantable endoprosthesis in a body lumen for a predetermined amount of time until the bioabsorbable and radiopaque materials are absorbed or dispersed in the body. The bioabsorbable material may include polylactide and the radiopaque material may include bismuth trioxide and barium sulfate. The weight percent of the radiopaque material in the bioabsorbable material may range from about 1% to about 80%. The radiopaque material may have a linear attenuation coefficient of from about 10 cm.sup.-1 at 50 KeV to about 120 cm.sup.-1 at 50 KeV.
