    Abstract: This disclosure is directed to prosthetic heart valves and actuation assemblies for prosthetic heart valves having actuators extending through actuation brackets secured to a prosthetic heart valve frame. In some examples, each actuator extends through and is pivotable relative to two actuation brackets secured to the inner surface of the prosthetic heart valve frame. In other examples, each actuator extends through and is pivotable relative to a vertically extending post of the frame. In this way, the actuators may move angularly relative to the longitudinal axis of the frame during the radial expansion and compression of the prosthetic heart valve. This may prevent bending and buckling of the actuators during the deployment of the prosthetic heart valve.

    Abstract: A prosthetic valve includes a frame having a first frame portion and a first window formed in the first frame portion. A threaded rod is coupled to the first frame portion and extends through the first window. Rotation of the threaded rod relative to the first frame portion radially expands or radially compresses the frame. A stopper is disposed within the first window and coupled to the threaded rod. The stopper is fixed in axial position relative to the threaded rod and axially movable within the first window by rotation of the threaded rod. The stopper can engage a first edge of the window to produce radial compression of the frame.

    Abstract: This disclosure is directed to prosthetic heart valves having frames with features configured to increase the flexibility of certain frame components and/or to allow the frame to maintain an at least substantially cylindrical shape during deployment. In one example, a frame for an implantable device can include a first end, a second end, a plurality of angled struts, and a plurality of vertical struts. One or more vertical struts of the plurality of vertical struts includes a fixed end portion connected to a vertical strut junction, a free end portion, and a plurality of apertures disposed between the fixed end portion and the free end portion and configured to increase the flexibility of the one or more vertical struts. In some examples, one or more vertical struts of the plurality of vertical struts comprises an axially compressible aperture configured to enable the axial compression of the strut.

    Abstract: Certain examples of the disclosure concern a prosthetic device. The prosthetic device can include a radially compressible and expandable frame and a screw actuator coupled to the frame and configured to be rotated to radially expand the frame from a radially compressed state to a radially expanded state. The frame can include two or more pairs of first markers and second markers. The pairs of first and second markers can be circumferentially spaced apart from each other. The first and second markers of each pair can be axially aligned and axially movable relative to one another as the frame radially expands. Positions of the first and second markers can be configured so that a difference in axial distances between respective pairs of the first markers and second markers can indicate a degree of evenness of the frame's radial expansion.

    Abstract: A delivery assembly constituted of: a prosthetic valve comprising a plurality of intersecting struts, and a delivery apparatus comprising: a handle; a delivery shaft extending distally from the handle; and a flex sensing assembly, comprising: at least one flex sensor coupled to at least one of the plurality of struts; and a control unit in communication with the at least one flex sensor, wherein the prosthetic valve is movable between a radially compressed configuration and a radially expanded configuration, and wherein, responsive to an output of the at least one flex sensor, the control unit is configured to generate a signal indicative of a diameter of the prosthetic valve.
