    Abstract: Embodiments of prosthetic valves for implantation within a native mitral valve are provided. A prosthetic valve may comprise a radially compressible main body and a one-way valve portion. The prosthetic valve may further comprise one or more ventricular anchors coupled to the main body and disposed outside of the main body. The ventricular anchors may be configured such that a reduced profile of the prosthetic valve is possible. A space may be provided between an outer surface of the main body and the ventricular anchors for receiving native mitral valve leaflets. The prosthetic valve may include an atrial sealing member adapted for placement above the annulus of the mitral valve. Methods and devices for receiving the native mitral valve leaflets between the ventricular anchors and the main body are described.

    Abstract: A method for improving leaflet prolapse and/or valve regurgitation associated with a heart valve involves delivering a spacer device into a ventricle of a heart using a delivery system comprising a catheter, fixing the spacer device to a wall of the ventricle, expanding the spacer device to reposition a papillary muscle disposed in the ventricle away from the wall, the papillary muscle being connected to a leaflet of an atrioventricular heart valve via chordae tendineae, and releasing the spacer device from the catheter.

    Abstract: Embodiments of a prosthetic heart valve are disclosed. An implantable prosthetic valve may be radially collapsible to a collapsed configuration and radially expandable to an expanded configuration. The prosthetic valve may comprise an annular frame, a leaflet structure positioned within the frame and a plurality of outer skirts positioned around an outer surface of the frame, each outer skirt comprising an inflow edge secured to the frame and an outflow edge secured at intervals to the frame. The plurality of outer skirts may include a first outer skirt and a second outer skirt, wherein in the expanded configuration the first and second outer skirts include openings unsecured to the frame between the intervals. The inflow edge of the first annular outer skirt may be secured to the frame with sutures including radiopaque material. The first annular outer skirt may include radiopaque dye.

    Abstract: A method of assembling a prosthetic heart valve comprises securing a suture loop having at least first and second windings to an outflow edge portion of an inner skirt. The first and second windings are arranged in a repeating pattern of figure-eight shape curves and each winding has a plurality of first sections attached to the outflow edge portion of the inner skirt and a plurality of second sections unattached to the inner skirt. The inner skirt is placed inside of an annular frame and the second sections of the first and second windings are placed over apices of an outflow end of the frame such that the second sections of the first and second windings reside outside of the frame. The second sections of the windings are inserted inwardly through openings in the frame and attached to selected locations on the inner skirt.

    Abstract: A prosthetic valve assembly includes a radially expandable and compressible annular frame. The frame includes a plurality of interconnected struts, which include a plurality of inner struts and a plurality of outer struts. The inner struts overlap adjacent outer struts at a plurality of pivot joints. Radial expansion or compression of the annular frame causes the inner struts to pivot relative to the outer struts at the pivot joints. The assembly also includes a valvular structure having a plurality of leaflets, each leaflet having a cusp edge portion. The assembly further includes one or more leaflet-supporting cords, each having a plurality of anchoring portions and a plurality of suspended portions, each suspended portion extending between two adjacent anchoring portions. The anchoring portions are affixed to respective anchoring features of the frame adjacent the pivot joints. The cusp edge portions of the leaflets are connected to the suspended portions.

    Abstract: Assembly methods for installing a leaflet assembly to an expandable frame of a prosthetic heart valve are described. The leaflet assembly comprises a plurality of leaflets coupled together at adjacent tabs, which form respective commissure tab assemblies. The commissure tab assemblies are inserted into corresponding windows of support members of the expandable frame. One or more wedge members are inserted into the commissure tab assembly, e.g., between the adjacent tabs or with the adjacent tabs therebetween, to restrain radial motion of the commissure tab assembly with respect to the window. The window can be a closed window, and the wedge member insertion can be after the commissure tab assembly is inserted into the window. Alternatively, the window can be an open window or channel, and the wedge member insertion can be before the commissure tab assembly is installed in the window.
