Abstract: This disclosure is directed to prosthetic heart valves and frames for prosthetic heart valves having actuation assemblies with at least two bolts coupled to each other. The actuation assembly with at least two bolts allow different portions of the actuation assembly to be designed to meet different needs. In one example, the actuation mechanism can include a first bolt coupled end-to-end with a second bolt. The second bolt can have a greater diameter and correspondingly greater mechanical strength than the first bolt. The first bolt can have a lesser diameter suitable for minimizing the thickness of surrounding and adjacent valve frame components. The actuation assembly can also include one or more of a nut, a washer, and a portion designed to attach to components of a delivery system. Also disclosed herein are actuation assemblies including a washer secured by a pin extending through the bolt of the actuation assembly.

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: An implantable prosthetic device including a radially expandable and compressible frame having an inflow end portion and an outflow end portion. The frame including an actuator mechanism having a first frame member with a first inner bore and a second frame member with a second inner bore, the first and second frame members being spaced apart axially from one another, an actuator extending through the first and second inner bores, and a compressible cover member disposed over a portion of the actuator extending between the first and second frame members. Rotation of the actuator in a first direction causes the first and second frame members to move axially toward one another to expand the frame.

Abstract: A prosthetic device, such as a prosthetic heart valve, can include a frame that is radially expandable and compressible between a radially compressed state and a radially expanded state. In some examples, the prosthetic device can include locking mechanisms that are configured to hold the prosthetic device in a radially expanded state. In some examples, the locking mechanisms can be integrated into the frame of the prosthetic device.
