Abstract: In one embodiment, a method of assembling a prosthetic valve can comprise forming a radially expandable and compressible frame by pivotally joining together a plurality of struts without requiring individual rivets. In some embodiments, the frame is formed by interweaving the struts, which can be joined using integral hinges formed in the struts, such as by performing alternate cuts on the struts, bending the struts to form stopper tabs adjacent to joints and/or drilling holes in the struts to facilitate interconnecting struts at joints, or otherwise forming integral hinges and corresponding holes at junction points between the struts. In other embodiments, separate hinges are provided to interconnect the struts. In still other embodiments, separate flanged rivets are provided to connect the struts.

Abstract: Disclosed herein is a storage container for an expandable prosthetic heart valve that crimps the valve upon opening the container and removal of the valve from the container. The container includes a housing sized to receive the heart valve in its expanded configuration and a crimping mechanism. The crimping mechanism is incorporated into the container and engages the heart valve so as to operably convert the heart valve from its expanded configuration to its smaller crimped configuration upon opening the container and removing the valve.

Abstract: A prosthetic valve has an annular frame including a plurality of strut members that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration. A leaflet structure is situated at least partially within the frame. The leaflet structure includes a plurality of leaflets, each leaflet having opposing commissure tab portions on opposite sides of the leaflet. Each commissure tab portion is paired with an adjacent commissure tab portion of an adjacent leaflet to form a commissure. The commissure tab portions of each leaflet are folded to form a plurality of layers positioned on the inside of the frame. A reinforcement member is positioned between the layers of each commissure tab portion.
