System and method for assembling an endoluminal prosthesis
DCFirst Claim
1. A system for assembling an endoluminal prosthesis within a body lumen and for indicating the rotational orientation of a segment of said endoluminal prosthesis during insertion thereof into the body lumen, said system comprising:
- prosthesis segments configured for engagement to one another to form said endoluminal prosthesis in the body lumen;
radiographic indicia defined on at least one of said prosthesis segments and having different radiopacity from said prosthesis segment, wherein the composite radiographic image of said radiographic indicia varies with the rotational orientation of said prosthesis segment in the body lumen;
wherein the rotational orientation of said prosthesis segment in the body lumen is indicated by said radiographic image for optional adjustment of the rotational orientation.

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.

17. A method for assembling an endoluminal prosthesis within a body lumen and for determining the rotational orientation of a segment of said endoluminal prosthesis during insertion thereof into the body lumen, said method comprising the steps of:
-
(a) providing a first prosthesis segment with radiographic indicia having different radiopacity from the first prosthesis segment, wherein the composite radiographic image of the radiographic indicia varies with the rotational orientation of the first prosthesis segment in the body lumen; (b) inserting the first prosthesis segment into the body lumen; (c) detecting the radiographic image; (d) determining the rotational orientation of the first prosthesis segment in the lumen based on the radiographic image and optionally adjusting the rotational orientation of the first prosthesis segment based on the radiographic image, and (e) inserting a second prosthesis segment into the body lumen for engagement with the first prosthesis segment to form the endoluminal prosthesis in the body lumen. - View Dependent Claims (18, 19, 20, 21, 22, 23)
