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.

Claims

1. 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.

2. The aortic graft of claim 1, wherein the material is a material or synthetic fabric material inert to body fluids.

3. The aortic graft of claim 1, further comprising at least 4 struts arranged essentially parallel to the major axis thereof.

4. The aortic graft of claim 1 further comprising the upper end of said struts having fastening means above said angled hooks.

5. The aortic graft of claim 4, further comprising fastening means which are eyelets.

6. The aortic graft of claim 1, further comprising wherein the angled hooks are in a downward and outward direction from 10°

to 45°

.

7. The aortic graft of claim 6, further comprising wherein the barbs on said angled hooks are parallel to the struts.

8. The aortic graft of claim 1 further comprising the upper end of said tubular material having a resilient ring integral therewith which ring is capable of being compressed to a size smaller than its normal diameter.

9. The aortic graft of claim 1 further comprising a bifurcated structure wherein the flexible tubular material has two legs, one of said legs being shorter than the other.
