Abstract

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.

Claims

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.
