## Abstract

This invention is a system for the treatment of body passageways; in particular, vessels with vascular disease. The system includes an endovascular graft with a low-profile delivery configuration and a deployed configuration in which it conforms to the morphology of the vessel or body passageway to be treated as well as various connector members and stents. The graft is made from an inflatable graft body section and may be bifurcated. One or more inflatable cuffs may be disposed at either end of the graft body section. At least one inflatable channel is disposed between and in fluid communication with the inflatable cuffs.

## Claims

### Claim 1

An endovascular graft, comprising:
a tubular graft body section, comprising an inflatable portion;
a radially expandable stent extending from and affixed to the graft body section, said stent having a proximal end, a distal end and a serpentine ring configuration having a plurality of struts and apices;
at least one barb integrally formed as an extension of each strut extending distally from a position on the strut that is distal of an adjacent proximal apex; and
at least one tuck barb integrally formed in the struts to retain at least one barb,
wherein each strut and barb comprises a barb/strut interface in which there is no mechanical connection to join the barb to the strut.

### Claim 2

An endovascular graft, comprising:
a tubular graft body section, comprising an inflatable portion;
a radially expandable stent extending from and affixed to the graft body section, said stent having a proximal end, a distal end and a serpentine ring configuration having a plurality of struts and apices;
at least one barb integrally formed as an extension of each strut extending distally from a position on the strut that is distal of an adjacent proximal apex; and
at least one tuck slot integrally formed in the struts to retain at least one barb,
wherein each strut and barb comprises a barb/strut interface in which there is no mechanical connection to join the barb to the strut.
