    Abstract: Disclosed are techniques for construction of prosthetic heart valves, particularly techniques for attachment of scalloped edges of valvular leaflets to struts of mechanical frames using sutures and/or other materials as intermediate coupling members. In some embodiments, the scalloped edges of the leaflets are coupled to the segments of the struts of the frame via suture loops that are oriented transverse to the scalloped edges of the leaflets. In some embodiments, central portions of scallop line segments are attached to the scalloped edges of the leaflets and are not attached to the frame. In some embodiments, strut segments are tapered to limit translation of suture loops. In some embodiments, a cloth strip couples the scalloped edges of the leaflets to frame struts. In some embodiments, the scalloped edge is attached to adjacent segments of intersecting struts via sliding suture loops, where the adjacent segments join at a common pivot joint.

    Abstract: An implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration includes an annular frame including a plurality of angled strut members, and a skirt member secured to the frame. The skirt member includes a plurality of extension portions wrapped around at least one strut member adjacent the extension portions. The prosthetic valve further includes a cord member threaded through at least a portion of the plurality of extension portions to secure the skirt member to the at least one strut member.

    Abstract: A prosthetic heart valve according to the present disclosure comprises a radially collapsible and expandable annular frame and a leaflet structure comprising a plurality of leaflets mounted within the frame. The frame in particular embodiments can have commissure attachment portions that are configured to support the commissures of the leaflets at locations spaced radially inwardly toward the longitudinal flow axis of the prosthetic valve relative to the frame portions circumscribing the moveable portions of the leaflets. When the leaflets open under pressure of blood flowing through the prosthetic valve, the moveable portions of the leaflets are retained at positions spaced inwardly from the inner surface of the frame to protect against abrasion of the leaflets.

    Abstract: A method of implanting a prosthetic heart valve within a patient can comprise inserting a distal end portion of a delivery apparatus and a prosthetic heart valve into the patient and advancing the prosthetic heart valve to a deployment location within the heart of the patient and inflating one or more of a plurality of differently-sized balloons in a balloon-assembly on the distal end portion of the delivery apparatus. The prosthetic heart valve can be mounted on the balloon assembly in a crimped state and the inflating of the one or more of the plurality of differently-sized balloons can expand the prosthetic heart valve from the crimped state to a radially expanded state having a non-cylindrical shape.

    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: An implantable device can include a radially expandable frame configured to move between a radially compressed state and a radially expanded state. The frame including a plurality of struts, at least one actuator mechanism configured to compress and expand the frame, and at least one locking mechanism coupled to the actuator mechanism. A first strut and a second strut can be pivotably coupled to one another at a common junction and configured to move toward one another as the frame is compressed and away from one another as the frame is expanded. The first and second struts can have first and second locking features that extend from respective longitudinal side edges of the struts. The locking mechanism can include a locking member configured to extend between and engage the first and second locking features when the frame is expanded to retain the frame in the radially expanded state.
