COILED-SHEET STENT-GRAFT WITH SLIDABLE EXO-SKELETON

摘要

A stent-graft having an exo-skeleton attached to a tubular graft, the tubula r graft having a peripheral wall defining a lumen therein extending between first and second ends. One or more support elements, defining the exo- skeleton, are attached to the tubular graft, each support element extending generally peripherally around the tubular graft, each support element including generally axial segments and generally peripheral segments. A plurality of first fasteners attach the plurality of support elements to the wall of the tubular graft, at least one generally axial segment being slidab ly engaged by each first fastener. A plurality of second fasteners also attach the plurality of support elements to the wall of the tubular graft, each second fastener substantially anchoring a generally peripheral segment of th e respective support element to the wall of the tubular graft. The stent-graft also includes first and second stents on the first and second ends for substantially anchoring the respective ends within a body passage.
