Claim Text:
1. A replacement mitral valve for delivery to a native mitral valve to be secured relative to a native mitral valve annulus, the native mitral valve positioned between a left atrium and a left ventricle, the replacement mitral valve comprising: an expandable frame comprising a proximal end and a distal end and a longitudinal axis extending therethrough, the frame shaped to radially expand and collapse for deployment within the native mitral valve annulus; a plurality of proximal anchors connected to the frame and sized to contact the native mitral valve on an atrial side of the native mitral valve annulus, wherein when the frame is in an expanded configuration within the native mitral valve annulus, the plurality of proximal anchors extend radially outward on the atrial side of the native mitral valve annulus and extend at least partially distally; a plurality of distal anchors connected to the frame and sized to contact the native mitral valve on a ventricular side of the native mitral valve annulus, wherein when the frame is in an expanded configuration within the native mitral valve annulus: a valve body attached to the expandable frame; wherein radial expansion of the frame causes the plurality of distal anchors to draw closer to the plurality of proximal anchors; and wherein the replacement mitral valve is shaped such that, after the replacement mitral valve has been delivered to the native mitral valve and expanded, at least some of the plurality of proximal anchors contact tissue on the atrial side of the native mitral valve annulus and at least some of the plurality of distal anchors contact tissue on the ventricular side of the native mitral valve annulus.
