First Claim
Patent Images
1. An endovascular graft, comprising:
- a tubular graft body section;
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; and
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.

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.

29. A method of treating a patient'"'"'s vasculature, comprising
providing an endovascular graft that includes: -
a graft body section, a radially expandable stent extending from 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; and at least one barb integrally formed as an extension of a strut extending distally from a position on the strut that is distal of an adjacent proximal apex; delivering the graft to a treatment site within a patient'"'"'s body; and deploying the graft at the treatment site such that the integrally formed barbs extend distally generally parallel to an axis of a lumen in which they are deployed, partially penetrate a body passageway in which the graft is deployed and prevent axial migration of the graft due to distally oriented blood flow.
