An endoprosthesis includes a body defining a flow passage therethrough. The body is capable of maintaining patency in a blood vessel and includes iron or an alloy thereof. The body has a nano-structured surface comprising iron oxide in which the individual nano-structures have a height to thickness aspect ratio of at least 5:1. La présente invention concerne une endoprothèse incluant un corps définissant un passage d'écoulement à travers. Ledit corps est capable de maintenir la perméabilité dans un vaisseau sanguin et inclut du fer ou un alliage de fer. Ce corps possède une surface nano-structurée comprenant un oxyde de fer, les nano-structures individuelles présentant un rapport hauteur/épaisseur d'au moins 5/1.
