Abstract
A mitral valve implant includes a force-expanding mitral valve lattice having an interior orifice and a self-expanding valve trampoline attached at the interior orifice of the force-expanding mitral valve lattice. The mitral valve lattice is self-expandable to a first configuration and force expandable from the first configuration to a second configuration. The configurations can be circular or D-shaped. The mitral valve lattice comprises jack screws adjusting configurations of the mitral valve lattice. The valve trampoline has a cylindrical central region comprising valve leaflets. An outwardly flaring implant skirt is attached to the mitral valve lattice exterior. Wall-retaining wires are attached to the mitral valve lattice, are petal-shaped, and have a pre-set, radially outward, memory shape. The wires and skirt impart a force on a respective side of the native mitral valve when the mitral valve lattice is expanded within an annulus of the native mitral valve.
