Abstract
Abstract A system is provided for assembling an endoluminal prosthesis within a body lumen and for indicating the rotational orientation of a segment of the endoluminal prosthesis during insertion thereof into the body lumen. The system includes prosthesis segments configured for engagement to one another to form the endoluminal prosthesis in the body lumen. The system also includes radiographic indicia defined on at least one of the prosthesis segments and having different radiopacity from the prosthesis segment, wherein the composite radiographic image of the radiographic indicia varies with the rotational orientation of the prosthesis segment in the body lumen. The rotational orientation of the prosthesis segment in the body lumen is indicated by the radiographic image for optional adjustment of the rotational orientation.
