Claim:
1. A bioabsorbable stent comprising: an undeformed cylindrical radiopaque marker disposed in a cylindrical depot in a portion of the stent, wherein the marker comprises a sufficient radiopacity to be imaged by an imaging technique, wherein the cylindrical radiopaque marker remains undeformed after being coupled to the stent, at least some gaps between the undeformed cylindrical radiopaque marker and an internal surface of the cylindrical depot include a polymeric material, the depot extends partially through the portion of the stent such that only one of a luminal side and an abluminal side of the depot is open, and the bioabsorbable stent is fabricated from a polymer including poly(L-lactide-co-caprolactone) and the marker is a mixture or alloy of at least two types of metals for allowing the marker to be imaged by the imaging technique.
