Abstract:
1. A segmented substrate configured to receive one or more coatings and to be shaped into a crack-resistant endoprosthesis, the segmented substrate comprising: a first layered segment of said substrate including a first plurality of layers and having a first external surface and an opposite second external surface, the first external surface and the second external surface of the first layered segment defining a cross-sectional area having a first characteristic, the first layered segment being configured to be shaped into a first strut element having a low stress zone, said first plurality of layers of said first layered segment of said segmented substrate comprising: a second layered segment adjacent and connected to the first layered segment of said substrate including a second plurality of layers and having a third external surface and an opposite fourth external surface, the third external surface and the fourth external surface of the second layered segment defining a cross-sectional area having a second characteristic that is different than the first characteristic, the second layered segment being configured to be shaped into a second strut element having a bendable high stress zone, said second plurality of layers of said second layered segment of said segmented substrate comprising: wherein said first layered segment and said second layered segment are configured to receive one or more coatings upon one or more of said first external surface, said second external surface, said third external surface and said fourth external surface.
