Abstract: An expandable wedge implant for wedge osteotomies of the extremities has first and second components which are pivotally attached to each other such that up and down pivoting of the two components relative to one another causes increase and decrease of implant height. A pivot control structure is operably coupled to and between the two components to effect pivoting. Linear movement of a threaded ball on a threaded shaft associated with the first component while the threaded ball is concurrently constrained within an angled channel of the second component causes pivoting of the second component relative to the first component. Anchoring members associated with the first and second components attach the implant to adjacent vertebral bodies.

The method can also include rotating a plurality of jack screws connected to the mitral valve lattice. The jack screws can be configured to expand the mitral valve lattice from the first expanded configuration to a second expanded configuration.

For example, the customized device may use a first material for a frame and a second material for a liner, wherein the first material is more rigid than the second material. The customized device is fabricated using a three-dimensional printer that is capable of printing and bonding multiple different materials at the same time.
