An endoluminal prosthesis includes a tubular graft, an expandable annular support structure and a restraining mechanism restraining the prosthesis in a collapsed configuration in which the annular support structure is compressed to a low profile. The restraining mechanism holds the annular support structures in the collapsed configuration until the prosthesis is positioned for deployment. The restraining mechanism is then released to allow the annular support structures to expand into conforming engagement with the inner wall of a lumen in which the prosthesis is to be deployed. A feature according to the invention provides a balloon catheter onto which the prosthesis is loaded for deployment where the balloon is expanded to provide a radial force to release the restraining mechanism. Another feature provides for a restraining member that breaks upon application of the radial force to release the annular support structure from its constrained configuration. Another feature of the invention provides for independent and / or sequential release of the annular support members. Various types of annular support members attached to tubular grafts in a variety of manners may be used in accordance with the invention. The invention may be used in tubular grafts for endoluminal placement within a body lumen, including blood vessels, and for the treatment of abdominal and other aneurysms.
