1. An endoprosthesis, comprising:
- a framework;
a deposited metallic film on the framework, the film defining first and second opposed surfaces and a thickness of less than about 50 μ
m therebetween; and
at least one metal filament separate from the framework, the at least one filament defining a length, at least a portion of the filament along its length being embedded within the metallic film between the first and second surfaces.

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.
