1. 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;
a beading coupled to at least one of the first surface and the second surface of the layer; and
a radiopaque agent coupled to the beading to form a radiopaque beading.

Abstract
A device and method provides a graft having a layer of synthetic non-metallic material including a first surface and a second surface spaced apart from the first surface. The device further includes a beading coupled to the layer and a radiopaque agent coupled to the beading. Another device and method provides a implantable prosthesis having a stent frame, a first inner layer and a second outer layer defining a central axis. The implantable prosthesis further includes a beading coupled to at least one the layers.

17. A method of forming a graft device comprising:
-
disposing a radiopaque agent in a polymeric shell; compressing the radiopaque agent and shell to form a billet; extruding the billet so as to form a radiopaque beading; and wrapping the beading about a graft material so as to define a graft device. - View Dependent Claims (18, 19)

20. A method of observing a position of a graft in a body, the method comprises:
-
disposing a graft having a radiopaque beading in a body; exposing the body to an electromagnetic energy; and fluoroscopically observing at least a portion of the beading to determine the position of the graft in the body.

-
21. A method of verifying orientation of a graft in a mammalian body subsequent to implantation of such graft in the mammalian body without an incision into the body, the method comprising:
-
directing electromagnetic energies at the implanted graft; and forming an image on a display medium that shows the portion as a helically wound beading about the graft, the beading having greater contrast than another portion of the implanted graft.
