A radially expandable stent (10) comprising:
a biodegradable polymeric pattern of cylindrical rings and linking struts, the cylindrical rings being connected by the linking struts,
markers disposed in depots of the stent, wherein the markers comprise a sufficient radiopacity to be imaged by an imaging technique, wherein
the markers are coupled to the stent at least partially by an interference fit between the markers and a portion of an internal surface of the depots,
at least some gaps between the markers and the internal surface of the depots include a biocompatible polymeric material that acts as an adhesive for the markers, and wherein
the stent includes two or more markers distributed in a manner that facilitates visualization of the stent during and after implantation, and
each depot comprises only one marker. |
