Methods, systems, and devices seal off the branch port of a bifurcated endoluminal prosthesis to transform the bifurcated prosthesis to a single-lumen prosthesis. These methods and devices are available for fallback procedures when the deployment of a bifurcated endoluminal prosthesis is found to be impracticable. By effectively sealing off the second branch port, the attending physician is able to completely isolate an aneurysm or other disease of the vasculature. Where it is necessary and/or desirable to provide fluid communication between the trunk lumen and the second branch lumen, a separate passage may be provided between the first and second branches of the body lumen system.

Methods and articles for fabricating expansive stents having generally cylindrical configurations with a pattern therein include interconnecting portions from a generally planar sheet of material with a central portion. A pattern is formed in the sheet of material around said central portion corresponding to said pattern having interconnecting portions. The pattern has a generally circular outer margin. The pattern is separated from the sheet of material and causes relative movement between the central portion of the pattern and the outer circular margin in a direction perpendicular to the plane of the central portion. The pattern is transformed from one sheet form into one in cylindrical form to provide an expansible stent having a generally cylindrical configuration.
