Abstract: In one embodiment, a method of assembling a prosthetic valve can comprise forming a radially expandable and compressible frame by pivotally joining together a plurality of struts without requiring individual rivets. In some embodiments, the frame is formed by interweaving the struts, which 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 other embodiments, separate hinges are provided to interconnect the struts. In still other embodiments, separate flanged rivets are provided to connect the struts.

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: Disclosed herein is a storage container for an expandable prosthetic heart valve that crimps the valve upon opening the container and removal of the valve from the container. The container includes a housing sized to receive the heart valve in its expanded configuration and a crimping mechanism. The crimping mechanism is incorporated into the container and engages the heart valve so as to operably convert the heart valve from its expanded configuration to its smaller crimped configuration upon opening the container and removing the valve.

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: An implantable prosthetic valve assembly, according to one embodiment, comprises a frame assembly including a plurality of struts and a prosthetic valve secured inside the frame assembly by sutures. The sutures are inward of the outermost surface of an outer periphery of the frame assembly. In certain embodiments the struts contain recesses in which sutures can be disposed. In other embodiments, the struts can have holes through them which the sutures pass through. The implantable prosthetic valve assembly can also be collapsed within a catheter such that an outermost surface of a periphery of the frame assembly touches the catheter but the sutures are spaced apart from the catheter or are flush with the outer surface of the frame.

Abstract: A delivery apparatus including a measurement device to monitor the real-time diameter of a prosthetic heart valve can include a handle, at least one first actuator extending from the handle and being configured to apply a distally directed force to a proximal end portion of a prosthetic heart valve, at least one second actuator extending from the handle and being configured to apply a proximally directed force to a distal end portion of a prosthetic heart valve, a sensor, and first and second motion-transmitting members coupled to the first and second actuators, respectively, and having proximal ends coupled to the sensor, wherein the sensor senses relative movement between the motion-transmitting members upon actuation of the first and second actuators to determine the diameter of the prosthetic heart valve as it expands from a radially compressed configuration to a radially expanded configuration.

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.
