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 valve body defining a ventricular end of the device;
an annulus support that connects the atrial flange and the valve body, the annulus support including a ring of tabs extending radially therefrom;
wherein the atrial flange has a diameter greater than the diameter of the valve body, and the annulus support has a diameter between that of the diameter of the atrial flange and the diameter of the valve body.

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 valve body defining a ventricular end of the device, and an annulus support that connects the atrial flange and the valve body, the annulus support including a ring of tabs extending radially therefrom and adapted to engage the native mitral annulus and/or the native leaflet(s) of the human heart. The atrial flange can be seated in the atrium above the native mitral valve annulus in a human heart, and the ring of tabs can engage the native mitral annulus in a manner where the atrial flange and tabs provide a clipping effect to secure the mitral valve replacement device at the native mitral valve position

12. 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 valve body defining a ventricular end of the device; and an annulus support that connects the atrial flange and the valve body, the annulus support including a ring of tabs extending radially therefrom; seating the atrial flange in the atrium above a native mitral valve annulus in a human heart; and engaging the native mitral annulus and/or the native mitral valve leaflet(s) with the ring of tabs in a manner where the atrial flange and tabs provide a clipping effect to secure the mitral valve replacement device at the native mitral valve position. - View Dependent Claims (13, 14)

15. A heart valve, comprising:
-
a valve body; and a leaflet structure attached to the valve body, the leaflet structure comprising three leaflets, each leaflet having radial edges and outer edges, and wherein each outer edge of a leaflet is sewn to an outer edge of an adjacent leaflet along a longitudinal stitch line, and each radial edge of a leaflet is sewn to a radial edge of an adjacent leaflet along a radial stitch line, with the radial stitch line along one of radial edges extending from the longitudinal stitch lines towards a central point, wherein the leaflet structure further includes three inner stitch lines that originate from an apex that is offset from the central point, and which extend for a short distance towards the longitudinal stitch lines and merge with the longitudinal stitch lines, with the inner stitch lines forming an umbrella-shaped configuration for the combined three leaflets.
