Prosthesis for implantation in aorta and method of using same
Prosthesis for implantation in the ascending aorta comprising a tubular body made of biocompatible graft material, a cuff at the proximal portion of the tubular body for biasing pressure onto a sino-tubular junction and that is configured to conform to the junction. A stent assembly can also be used to the prosthesis to bias pressure on the wall of a dissection to substantially deflate a false lumen.
1. A prosthesis for implantation in the ascending aorta comprising:
a tubular body comprising biocompatible graft material;
a cuff at the proximal portion of the tubular body for biasing pressure onto a sino-tubular junction of an ascending thoracic aorta and is configured to conform to the sino-tubular junction; and at least one stent;
wherein the cuff further comprises a distal ring adjacent to the tubular body and a proximal ring; and
wherein the proximal ring has a larger diameter than the distal ring.
2. The prosthesis of claim 1 wherein the second tubular body is adapted for implantation in the descending aorta.
3. The prosthesis of claim 1 wherein the proximal ring and the distal ring are comprised of nitinol or stainless steel.
