  • Publication number: 20220387175
    Abstract: A prosthetic heart valve comprises an annular frame that is radially compressible and expandable between a radially compressed state and a radially expanded state, wherein the frame elongates in an axial direction when radially compressed from the radially expanded state to the radially compressed state. Leaflets are coupled to the frame such that when the frame is in the radially expanded state, the leaflets have slack in an axial direction, wherein when the frame is radially compressed to a partially radially compressed state between the radially expanded state and the radially compressed state, the leaflets are in a relaxed state, and wherein when the frame is in the radially compressed state, the leaflets are stretched in the axial direction.

  • Publication number: 20220346949
    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.

  • Publication number: 20220323210
    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.

  • Publication number: 20220160505
    Abstract: Disclosed are techniques for construction of prosthetic heart valves, particularly techniques for attachment of scalloped edges of valvular leaflets to struts of mechanical frames using sutures and/or other materials as intermediate coupling members. In some embodiments, the scalloped edges of the leaflets are coupled to the segments of the struts of the frame via suture loops that are oriented transverse to the scalloped edges of the leaflets. In some embodiments, central portions of scallop line segments are attached to the scalloped edges of the leaflets and are not attached to the frame. In some embodiments, strut segments are tapered to limit translation of suture loops. In some embodiments, a cloth strip couples the scalloped edges of the leaflets to frame struts. In some embodiments, the scalloped edge is attached to adjacent segments of intersecting struts via sliding suture loops, where the adjacent segments join at a common pivot joint.
