Abstract

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.

Claims

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 μ

m 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.

2. An endoprosthesis for deployment within a body passage, comprising:

a framework having a plurality of projections disposed along a length of the framework, wherein each of the projections has a first end and second fixed end disposed on the surface of the framework;

a tubular member comprising a metallic film having a thickness of about 50 μ

m or less and being generally coextensive with at least a portion of the framework, the tubular member having a plurality of fenestrations such that the each of the plurality of projections passes through a different fenestration; and

a plurality of circumferential filaments, wherein a circumferential filament passes through the first and second fixed ends of a plurality of projections around a circumference of the framework to retain the framework and the tubular member with respect to one another, wherein each of the projections has a first and second fixed end, and wherein the at least one filament extends between the first and second fixed ends.
