Medical devices including metallic films

摘要

An endoprosthesis for deployment within a body passage includes a framework and a metallic film, which can circumferentially surround the framework or be surrounded by the framework. The framework and metallic film can be attached without using a third material, e.g., without sewing. The framework can define a circumferential recess along at least a portion of its length and circumference. The recess accommodates at least a portion of the metallic film therein.

1. An endoprosthesis for deployment within a body passage, comprising:
a framework having a plurality of projecting eyelets disposed along a length of the framework; a tubular member comprising a metallic film having a thickness of about 50 μm or less and being generally coextensive with at least a portion of the framework, the tubular member having a plurality of fenestrations such that each eyelet passes through a different fenestration; and a plurality of circumferential filaments, wherein a circumferential filament passes through a plurality of eyelets around a circumference of the framework to retain the framework and the tubular member with respect to one another.
