Abstract
A prosthesis comprising a graft and an expandable stent underlying the graft, the stent and graft being linked together only at or near their distal ends. The difference in stent length between compressed and expanded radial configurations may exceed the difference in graft length between such configurations. An introducer for such prosthesis comprises an interior sheath axially mounted inside an exterior sheath, with the graft positioned between the interior and exterior sheaths and the stent compressed at least partially inside the interior sheath. A method for deploying the prosthesis using such an introducer may include positioning the introducer distal end upstream relative to proximally flowing endoluminal fluid so that the endoluminal fluid may flow between the graft and inner sheath during stent deployment.
