摘要： 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.

摘要： A delivery apparatus comprises a handle portion and at least one rotatable drive shaft. The handle portion has an actuation mechanism and a display. The actuation mechanism includes a motor and one or more actuators. The rotatable drive shaft has a proximal end portion and a distal end portion. The proximal end portion is coupled to the motor, and the distal end portion is configured to be releasably coupled to a prosthetic heart valve. The actuation mechanism is configured to control and monitor expansion of the prosthetic heart valve, and the display is configured to display a diameter of the prosthetic heart valve.

摘要： Sealable and repositionable implant devices are provided to increase the ability of endovascular grafts and valves to be precisely deployed or re-deployed, with better in situ accommodation to the local anatomy of the targeted recipient anatomic site, and with the ability for post-deployment adjustment to accommodate anatomic changes that might compromise the efficacy of the implant. A surgical implant includes a self-expanding stent of a shape-memory material set to a given shape. The stent has a wall with a portion having a first thickness and a second portion having a thickness greater than the first. The second portion defines a key-hole shaped longitudinal drive orifice. The implant includes a selectively adjustable assembly having adjustable elements and being operable to force a configuration change in at least a portion of the self-expanding stent. The adjustable elements have a part rotatably disposed within the longitudinal drive orifice.

摘要： A prosthetic heart valve includes a frame, a valve, and an expansion element. The frame is movable between contracted and expanded configurations and includes first struts and second struts non-hingedly coupled together. The second struts are configured to pivot relative to the first struts as the frame moves between the contracted and expanded configurations. The valve is coupled to the frame and includes leaflets. The expansion element extends through a lumen of the first struts. The expansion element is slidable relative to the lumen of the first struts and is configured to move the frame incrementally from the contracted configuration and the expanded configuration and from the expanded configuration to the contracted configuration.

The proximal end portion is coupled to the motor, and the distal end portion is configured to be releasably coupled to a prosthetic heart valve. The actuation mechanism is configured to control and monitor expansion of the prosthetic heart valve. The handle is configured for actuating the actuation mechanism, tracking a response of native tissue when the prosthetic heart valve is in contact with the native tissue, and stopping expansion of the prosthetic heart valve once a rate of change of expansion of the prosthetic heart valve declines below a threshold.
