An endoluminal prosthesis (10, 40; 400; 450) that is adapted for placement within a body lumen, said prosthesis (10, 40; 400; 450) comprising radiopaque marker means (17; 17a; 120; 420) thereon, which radiopaque marker means (17; 17a; 120; 420) is configured to indicate the rotational alignment of said prosthesis (10, 40; 400; 450), or the alignment of said prosthesis (10, 40) with another prosthesis (40, 10), during placement thereof in the body lumen. Also disclosed are a method of determining the rotational alignment of an endoluminal prosthesis (10; 40; 400; 450) during placement thereof in a body lumen, and a method for determining the proper alignment of a plurality of portions (10; 40) of an endoluminal prosthesis during assembly of said endoluminal prosthesis within the vasculature of a body. |
