Abstract: A prosthetic device, such as a prosthetic heart valve, can include a frame comprising a plurality of axially extending posts and a plurality of struts that connect the plurality of axially extending posts. One or more of these posts can be configured as expansion and locking mechanisms. For example, the posts that are configured as expansion and locking mechanisms can include proximal and distal members that are axially movable relative to one another, and are moveable via rotation of a threaded rod connected therebetween. An actuation assembly can include three-subassemblies configured for actuation of the threaded rod, and can be configured to limit unwanted axial and rotational movement of the prosthetic heart valve during radial expansion and/or compression of the frame.

Abstract: Prosthetic valves that include support arms extending from support posts thereof, and methods for utilizing such prosthetic valves, are disclosed herein. As one example, a prosthetic valve can include an annular frame movable between a radially compressed state and a radially expanded state, and at least one support arm. The frame can include a plurality of support posts, each extending between a post inflow end and an opposite post outflow end. The support arm can extend from a corresponding support post, and terminate at a free-ended tip which is biased radially away from the corresponding support post.
