Abstract
Disclosed is a tubular endoluminal vascular prosthesis, useful in treating, for example, an abdominal aortic aneurysm. The prosthesis comprises a self-expandable wire support structure having a tubular main body support and first and second branch supports. The support structure may include sliding links to permit flexibility while maintaining patency of the central lumen. The branch supports may articulate with the main body to permit the branches to pivot laterally from the axis of the main body throughout a substantial range of motion. Exoskeleton components or barbs may be provided to resist migration and endoleaks.
