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.
