1. A replacement mitral valve, comprising:
- an anchor assembly comprising a ventricular anchor, an annular central portion, and an atrial anchor, wherein the anchor assembly includes a plurality of first apertures extending therethrough;
a cylindrical strut frame disposed radially within the anchor assembly, wherein the cylindrical strut frame is not integral with the anchor assembly and includes a plurality of strut members and a frame portion including a plurality of arches which define a plurality of peaks and a plurality of valleys at a proximal end of the strut frame, the plurality of valleys being spaced circumferentially around the strut frame, and a plurality of second apertures extending through the plurality of valleys, each of the plurality of second apertures being located at an apex of one of the plurality of valleys; and
a plurality of couplers, each coupler extending through one of the first apertures and one of the second apertures to couple the cylindrical strut frame to the anchor assembly at each of the first and second apertures,wherein the replacement mitral valve is configured to self-expand from a constrained configuration to an expanded configuration in which the ventricular anchor and the atrial anchor are flared radially outward relative to the annular central portion, and the plurality of strut members extend further distally than the plurality of peaks.

13. A replacement mitral valve, comprising:
-
an anchor assembly comprising a ventricular anchor, an annular central portion, and an atrial anchor; a cylindrical strut frame disposed radially within the anchor assembly and including a plurality of strut members and a frame portion including a plurality of arches defining a plurality of peaks and a plurality of valleys at a proximal end of the strut frame, the plurality of valleys being spaced circumferentially around the strut frame; and a plurality of rivets, each rivet extending through the annular central portion and through an apex of one of the plurality of valleys of the cylindrical strut frame to secure the cylindrical strut frame to the anchor assembly; wherein the replacement mitral valve is configured to self-expand from a constrained configuration to an expanded configuration in which the ventricular anchor and the atrial anchor are flared radially outward relative to the annular central portion, and the plurality of strut members extend further distally than the plurality of peaks. - View Dependent Claims (14, 15, 16)
