1. A graft device comprising:
- an extruded layer of synthetic non-metallic material having a first surface and a second surface spaced apart from the first surface; and
a co-extruded first radiopaque marker and a coextruded second radiopaque marker each at least partially embedded in the layer, the first radiopaque marker being formed of a first radiopaque material and the second radiopaque marker being formed of a second radiopaque material different from the first radiopaque material.

15. A device comprising:
-
a stent frame; an extruded synthetic non-metallic material that surrounds a portion of the stent frame, the synthetic non-metallic material having first and second surfaces; and a first co-extruded radiopaque strip and a second coextruded radiopaque strip embedded in the nonmetallic material, the first radiopaque strip and the second radiopaque strip each formed from a combination of at least two different radiopaque materials.

16. A method of forming a graft device comprising:
-
extruding a synthetic non-metallic material so as to form a member having a first surface and a second surface spaced apart from the first surface, wherein extruding includes extruding a first radiopaque material into a first continuous line and extruding a second radiopaque material into a second continuous line such that the first radiopaque material and the second radiopaque material are at least partially embedded in the non-metallic material, the second radiopaque material being different from the first radiopaque material. - View Dependent Claims (17, 18)

19. A graft device comprising:
-
a layer of synthetic non-metallic material having a first surface and a second surface spaced apart from the first surface; and a first orientation line and a second orientation line disposed along at least one of the first and second surfaces, the first orientation line formed by a radiopaque marker of a first radiopaque material mixed with a coloring agent coextruded with the layer of synthetic non-metallic material, and the second orientation line formed by a radiopaque marker of a second radiopaque material different from the first material that is not mixed with a coloring agent but is coextruded with the layer of synthetic nonmetallic material. - View Dependent Claims (20)
