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.
