Abstract: In one embodiment, a prosthetic valve can comprise a radially expandable and compressible frame, which can include a plurality of struts which are pivotally joined together without requiring individual rivets. In some embodiments, the struts are interwoven, and can be joined using integral hinges formed in the struts, such as by performing alternate cuts on the struts, bending the struts to form stopper tabs adjacent to joints and/or drilling holes in the struts to facilitate interconnecting struts at joints, or otherwise forming integral hinges and corresponding holes at junction points between the struts. In another embodiment, the frame comprises a plurality of inner struts and outer struts which are connected by a plurality of chains of interconnected rivets, avoiding the need to provide individual rivets at each junction between struts. In still another embodiment, separate hinges or flanged rivets are provided to interconnect the struts.

Abstract: A radially expandable prosthetic valve can comprise an annular frame, at least one expansion mechanism and a cord. The annular frame can be radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration. The expansion mechanism can comprise a first member attached to the frame at a first location and a second member attached to the frame at a second location axially spaced from the first location. The cord can extend at least partially along the expansion mechanism in a first direction, be reeved around a portion of the second member, and extend at least partially along the expansion mechanism in a second direction opposite the first direction. Applying a proximally directed force to a first portion of the cord can cause the second member to move relative to the first member, which can cause the frame to foreshorten axially and expand radially.

Abstract: An assembly can comprise a prosthetic valve comprising a radially expandable and compressible frame and a rotatable screw connected to the frame, where the screw comprises a screw head having an annular bore with internal threads, and where the screw is rotatable to radially expand the frame. The assembly further comprises a delivery apparatus releasably coupled to the screw, the delivery apparatus comprising a first shaft and a first head disposed at an end of the first shaft, the first head comprising external threads configured to engage with the internal threads of the screw head, and a second shaft that is coaxial with and surrounds the first shaft, the second shaft comprising a second head disposed at an end of the second shaft. The second head is configured to releasably engage with an exterior surface of the screw head and rotate the screw.

Abstract: Disclosed herein is a crimping device for crimping a prosthetic heart valve. The crimping device includes a plurality of crimping jaws circumferentially arranged around a crimping orifice having a central crimping axis, each crimping jaw having an inner crimping wedge. The crimping device also includes a rotating cam wheel adapted to act on the crimping jaws, a stationary outer housing containing the crimping jaws and the cam wheel, and a plurality of guide elements. Each guide element is constrained by fixed grooves in the outer housing for translating the crimping jaws inwardly toward the crimping axis, thereby reducing a size of the crimping orifice. Molded halves are provided for sandwiching the rotating cam wheel, the crimping jaws, and the guide elements.

Abstract: A method can comprise deploying a prosthetic valve with a delivery apparatus, where the prosthetic valve comprises a frame and a rotatable screw connected to the frame, and where the screw comprises a screw head having an annular bore with internal threads. The delivery apparatus is releasably coupled to the screw and can comprise a first shaft and a first head disposed at an end of the first shaft, the first head comprising external threads releasably engaged with the internal threads of the screw head, and a second shaft that is coaxial with and surrounds the first shaft, the second shaft comprising a second head disposed at an end of the second shaft, the second head releasably engaged with an exterior surface of the screw head. Deploying the valve includes radially expanding the prosthetic valve by rotating the screw with the delivery apparatus.

Abstract: Disclosed herein is a method of crimping a prosthetic heart valve using a compact crimping mechanism. The crimping mechanism includes a plurality of jaws configured for coordinated inward movement toward a crimping axis to reduce the size of a crimping iris around a stented valve. A rotating cam wheel acts on the jaws and displaces them inward. An actuation mechanism includes a lead screw, carriage assembly and a linkage to rotate the cam wheel with significant torque.

Abstract: A method for improving leaflet prolapse and/or valve regurgitation associated with a heart valve involves delivering a spacer device into a ventricle of a heart using a delivery system comprising a catheter, fixing the spacer device to a wall of the ventricle, expanding the spacer device to reposition a papillary muscle disposed in the ventricle away from the wall, the papillary muscle being connected to a leaflet of an atrioventricular heart valve via chordae tendineae, and releasing the spacer device from the catheter.

Abstract: Docking stations for transcatheter valves are described. The docking stations can include an expandable frame, at least one sealing portion, and a valve seat. The expandable frame can be configured to conform to an interior shape of a portion of the circulatory system when expanded inside the circulatory system. The sealing portion can be configured to contact an interior surface of the circulatory system to create a seal. The valve seat can be connected to the expandable frame and can be configured to support an expandable transcatheter valve. The docking stations are adaptable to different anatomies/locations to allow implantation of a transcatheter valve in a variety of anatomies/locations.
