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 inckudes 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.
