1. A cardiac valve prosthesis, comprising:
- an annulus body defining a passage therethough having a first open end and a second open end, wherein at least a portion of an inner surface of the passage tapers inwardly toward a longitudinal axis of the annulus body as the passage extends from the first open end to the second open end, wherein the diameter of the first open end is greater than the diameter of the second open end, and wherein the valve prosthesis is configured to replace a deficient native valve.

Abstract
Provided herein is a cardiac valve prosthesis comprising a annulus body having a back face and defining a passage for the flow of blood along an axis of the passage. The passage has a first open end having a greater diameter that its opposed second open end. In a further aspect, the valve prosthesis includes means for creating a fluid barriers to the flow of fluid therethrough the passage of the annulus body.

31. A method of replacing a deficient native valve, comprising the steps of:
-
providing a cardiac valve prosthesis comprising an annulus body defining a passage therethough having a first open end and a second open end, the passage having an inner surface, wherein at least a portion of the inner surface of the passage tapers inwardly toward a longitudinal axis of the annulus body as the passage extends inwardly from the first open end to the second open end, and wherein the diameter of the first open end is greater than the diameter of the second open end;
collapsing the annulus body to fit within a distally positioned sheath on a catheter;
advancing the catheter to the deficient native valve;
deploying the annulus body of the valve prosthesis; and
withdrawing the catheter, leaving the valve prosthesis to function in place of the deficient native valve.
