Abstract
Abstract An aortic graft that is specifically constructed for intraluminal insertion and comprising a flexible hollow, tubular material, having a generally cylindrical shape with an upper end and lower end and having a minor and major axis, and having disposed along its major axis a plurality of parallel struts, the struts having angled hooks with barbs at their upper ends, the upper ends of the struts extending beyond the upper end of the tubular material, thus allowing the graft to be securely attached to the inside of the aorta above the aneurysm. A tubular device for inserting the graft is also disclosed.
