Abstract: A prosthetic heart valve includes a valve frame comprising an outflow end and an inflow end, a plurality of leaflets disposed within and coupled to the valve frame, and a skirt assembly mounted to an outer surface of the valve frame. The skirt assembly includes a sealing layer and a skirt frame including a plurality of interconnected struts, wherein the skirt frame has a plurality of inflow apices and outflow apices, wherein selected ones of the inflow apices are fixed to the valve frame and selected ones of the outflow apices are fixed to the valve frame, wherein one or more of the struts are configured to flex in an outward radial direction when the valve frame is in a radially expanded state to cause the sealing layer to protrude outwardly from the valve frame.

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: 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.
