Abstract
Physical vapor deposition of radiopaque markings onto a graft is described. A graft is placed into a chamber, and a radiopaque material is vaporized and then deposited onto the graft. The chamber is kept at a temperature below the damage threshold of the graft material. A template optionally placed on the graft may define the design of the deposited radiopaque markings. The deposited radiopaque markings of the present invention may have any design and may comprise any radiopaque material.
