Abstract
An aortic stent graft includes a stent with a framework attached to a fabric tube by a plurality of suture ties. The fabric tube includes a plurality of discrete attachment areas that are at least partially surrounded by at least one permeable graft area. The fabric tube is one of a weave and a knit of thermoplastic yarn. Each of the suture ties associated with the discrete attachment areas at least one of penetrates through and encircles a respective one of the discrete attachment areas. The weave or knit of the discrete attachment areas is identical to that of the permeable graft area with an exception that a wall thickness of each of the discrete attachment areas is flattened relative to, and thinner than, a wall thickness of the permeable graft area.
