Prosthetic Heart Valve Devices and Methods of Valve Replacement
First Claim
1. A stented valve comprising:
- a stent frame comprising;
an annular portion comprising first and second ends, and a central longitudinal axis,an atrial portion extending from the first end of the annular portion, wherein the atrial portion flares radially outward relative to the longitudinal axis of the annular portion; and
a ventricular portion extending from the second end of the annular portion, wherein the ventricular portion flares radially outward relative to the longitudinal axis of the annular portion; and
a prosthetic valve comprising a first leaflet and a second leaflet attached within an interior area of the stent frame, and at least one chord attached to the first leaflet and the stent frame.

Abstract
A stented valve of two or more leaflets made of pericardium or other material having a relatively thin profile at the annulus. The leaflet surfaces are attached via chords to a stent frame, where the chords are positioned to mimic the native valve anatomy and functionality. In particular, the valves of one exemplary embodiment of the invention are sized to replace a mitral valve and therefore the chords are arranged to prevent prolapse of the leaflets into the atrium. The stented valve has a relatively short height at its annulus due to the positioning of the chords. In addition, the stented valve is capable of being crimped to a small enough size that it can be delivered to the implantation site via transcatheter delivery systems and methods.
