1. An endoprosthesis, comprising:
- a metallic film defining first and second opposed surfaces and a thickness of less than about 50 μ
m therebetween; and
at least one filament, the at least one filament defining a length, at least two portions of the filament along its length being embedded within the metallic film between the first and second surfaces, the two portions being separated by a non-embedded portion of the filament.

Abstract
Medical devices, such as endoprostheses, and methods of making the devices are disclosed. The medical device can include a composite cover formed of a deposited metallic film. The cover may include one or more filaments, e.g., wires, which cooperate with the film to provide desirable mechanical properties. The wires may be integrated with the film by depositing the film over the wires.
