Abstract
Abstract Disclosed is a tubular prosthesis formed by rolling a flexible sheet around a longitudinal axis. Preferably, the prosthesis is self expandable under the radially outwardly directed spring bias of the rolled sheet. Also disclosed are catheters for delivering two or more of the tubular prostheses at a site within a body lumen. Multiple prostheses may be deployed directly against a vessel wall in a single procedure, or may be deployed within a vascular graft to provide support throughout the length of the graft.
