Abstract

L'invention concerne un dispositif médical comprenant un revêtement poreux radiopaque qui peut résister à des contraintes élevée inhérentes à l'utilisation de ces dispositifs sans délaminage. On applique une couche de tantale (T) sur un dispositif médical, tel qu'un stent, par dépôt en phase vapeur, de façon à ne pas affecter négativement les propriétés thermo-mécaniques du stent. Ledit revêtement présente, de préférence, une émissivité élevée.
