Device and Method for Mitral Valve Regurgitation Treatment
First Claim
1. A mitral valve replacement device adapted to be deployed at a mitral valve position in a human heart, comprising:
- an atrial flange defining an atrial end of the device;
a ventricular portion defining a ventricular end of the device, the ventricular portion having a height ranging between 2 mm to 15 mm;
an annulus support that is positioned between the atrial flange and the ventricular portion, the annulus support including a ring of anchors extending radially therefrom, with an clipping annular space defined between the atrial flange and the ring of anchors;
a plurality of leaflet holders positioned at the atrial end of the atrial flange; and
a plurality of valve leaflets secured to the leaflet holders, and positioned inside the atrial flange at a location above the native annulus.

Abstract
A mitral valve replacement device is adapted to be deployed at a mitral valve position in a human heart. The device has an atrial flange defining an atrial end of the device, a ventricular portion defining a ventricular end of the device, the ventricular portion having a height ranging between 2 mm to 15 mm, and an annulus support that is positioned between the atrial flange and the ventricular portion. The annulus support includes a ring of anchors extending radially therefrom, with an annular clipping space defined between the atrial flange and the ring of anchors. A plurality of leaflet holders positioned at the atrial end of the atrial flange, and a plurality of valve leaflets secured to the leaflet holders, and positioned inside the atrial flange at a location above the native annulus.

9. A method of deploying a mitral valve replacement device at a native mitral valve position in a human heart, comprising:
-
providing a mitral valve replacement device comprising; an atrial flange defining an atrial end of the device; a ventricular portion defining a ventricular end of the device, the ventricular portion having a height ranging between 2 mm to 15 mm; an annulus support that is positioned between the atrial flange and the ventricular portion, the annulus support including a ring of anchors extending radially therefrom, with an annular clipping space defined between the atrial flange and the ring of anchors; a plurality of leaflet holders positioned at the atrial end of the atrial flange; and a plurality of valve leaflets secured to the leaflet holders, and positioned inside the atrial flange; seating the atrial flange in the atrium above a native mitral valve annulus in a human heart in a manner where the plurality of leaflets are positioned above the native annulus; and positioning the native mitral annulus and/or the native mitral valve leaflet(s) in the clipping space. - View Dependent Claims (10, 11)
