A stent having long-term antithrombogenicity andnradiopacity whose location and geometry can benradiographically confirmed is provided. The productionnmethod is also provided. The stent of the invention has annantithrombogenic agent covalently bonded on its surface, andnthe antithrombogenic agent is immobilized onto the stentnsurface through a coupling agent having at least two aminongroups and a cross-linking agent having at least twonaldehyde and/or epoxy groups. The stent of the invention maynalso have radiopaque metal plating on at least a partnthereof. |
