Endovascular Prosthesis for Ascending Aorta
First Claim
1. An endoluminal prosthesis comprising:
- a tubular graft material having an outer surface and an inner surface;
a support structure coupled to the graft material; and
a plurality of anchors extending from a proximal end of the support structure, wherein each anchor is curved outwardly such that a middle portion of the anchor extends further outwardly than a proximal portion of the anchor and a distal portion of the anchor.

Abstract
An endoluminal prosthesis for use in the ascending aorta is disclosed. The prosthesis includes a tubular graft material having an outer surface and an inner surface, a support structure coupled to the graft material, and a plurality of anchors extending from a proximal end of the support structure. Each anchor is curved outwardly such that a middle portion of the anchor extends further outwardly than a proximal portion of the anchor and a distal portion of the anchor such that the anchors conform to the shape of the aortic root. A hook extends outwardly from a proximal end of each anchor to engage the annulus of the aortic valve. The proximal end of the support structure and graft material is disposed adjacent the sinotubular junction.
