Abstract:
1. A replacement mitral valve configured to be delivered to a native mitral valve and 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 extending along a longitudinal axis between a first end and a second end, the frame comprising a first portion and a second portion, the first portion being closer to the first end than the second portion is to the first end, and the second portion being closer to the second end than the first portion is to the second end, wherein the second portion comprises a plurality of foreshortening cells and the first portion comprises a plurality of struts having at least a portion thereof extending longitudinally from foreshortening cells of the second portion toward the first end of the frame; wherein the first portion comprises a non-foreshortening portion that does not substantially foreshorten when the frame is radially expanded; a first plurality of anchors connected to the first portion of the frame, wherein the first plurality of anchors are positioned radially outward from a portion of the frame when the frame is in an expanded configuration; a second plurality of anchors connected to the second portion of the frame, wherein the second plurality of anchors extend radially outward from the frame and extend in a direction generally toward the first end when the frame is in an expanded configuration; and a valve body attached to the expandable frame; wherein radial expansion of the frame causes the plurality of first plurality of anchors and the second plurality of anchors to draw closer together.
