Abstract

A prosthetic stentless aortic tissue valve includes a substantially annular valve body having a leaflet carried therein for occluding blood flow therethrough. A root extends generally coaxially from the valve body. Visual marking are provided on the root and act as a sculpting guide for a surgeon during implantation of the prosthetic heart valve to sculpt portions of sinus areas of the root.

Claims

1. A prosthetic stentless aortic valve for replacing a natural aortic heart valve of a patient, comprising:

a substantially annular valve body including a leaflet carried therein for occluding blood flow through the valve body;

an aortic root having an interior surface and an exterior surface spaced from the interior surface, the root including sinus areas and extending generally coaxially from the valve body; and

a visual marking carried substantially on the exterior surface of the aortic root providing a sculpting guideline thereon for use during implantation of the prosthetic heart valve to sculpt portions of the sinus areas of the aortic root, wherein the visual marking does not penetrate the interior surface.

2. The prosthetic stentless aortic valve of claim 1 wherein the leaflet extends into the aortic root and the visual marking generally conforms to the leaflet.

3. The prosthetic stentless aortic valve of claim 1 including a plurality of visual markings on the aortic root.

4. The prosthetic stentless aortic valve of claim 1 wherein the visual marking comprises a biocompatible dye applied to the aortic root.

5. The prosthetic stentless aortic valve of claim 1 including a plurality of leaflets.

6. The prosthetic stentless aortic valve of claim 1 wherein the visual marking does not promote mineralization of the tissue matrix.
