DEVICE AND METHOD FOR REPLACING MITRAL VALVE
First Claim
1. A prosthetic mitral valve assembly, comprising:
- a radially-expandable stent including a lower portion sized to held between leaflets of a native mitral valve and an upper portion having a flared end, the upper portion sized for deployment within the annulus of the mitral valve with a pressure fit, the flared end configured to extend above the annulus, wherein the stent tapers from the upper portion to the lower portion, the stent having a substantially D-shape cross-section for conforming to the native mitral valve, the D-shape cross-section providing a substantially straight portion configured to extend along an anterior side of the native mitral valve and a substantially curved portion configured to extend along a posterior side of the native mitral valve; and
a valve portion formed of pericardial tissue and mounted within an interior portion of the stent, the valve portion having leaflets for occluding blood flow in one direction and replacing the function of the native mitral valve.

Abstract
A prosthetic mitral valve assembly is disclosed. The assembly comprises a radially-expandable stent including a lower portion sized for deployment between leaflets of a native mitral valve and an upper portion having a flared end. The upper portion is sized for deployment within the annulus of the mitral valve and the flared end is configured to extend above the annulus. The stent is formed with a substantially D-shape cross-section for conforming to the native mitral valve. The D-shape cross-section includes a substantially straight portion for extending along an anterior side of the native mitral valve and a substantially curved portion for extending along a posterior side of the native mitral valve. The assembly further includes a valve portion formed of pericardial tissue and mounted within an interior portion of the stent for occluding blood flow in one direction.
