Abstract: Embodiments of a radially collapsible and expandable prosthetic heart valve are disclosed. A valve frame can have a tapered profile when mounted on a delivery shaft, with an inflow end portion having a smaller diameter than an outflow end portion. The valve can comprise generally V-shaped leaflets, reducing material within the inflow end of the frame. An outer skirt can be secured to the outside of the inflow end portion of the frame, the outer skirt having longitudinal slack when the valve is expanded and lying flat against the frame when the valve is collapsed. A diagonally woven inner skirt can elongate axially with the frame. Side tabs of adjacent leaflets can extend through and be secured to window frame portions of the frame to form commissures. The window frame portions can be depressed radially inward relative to surrounding frame portions when the valve is crimped onto a delivery shaft.

Abstract: A method of crimping an implantable prosthetic valve can include placing protective material over at least a portion of the implantable prosthetic valve. The protective material can be configured to occupy space between open cells of a frame of the implantable prosthetic valve to prevent damage to a leaflet structure of the implantable prosthetic valve. The method can also include crimping the implantable prosthetic valve with the protective material on the implantable prosthetic valve, and removing the protective material from between the frame and the leaflet structure of the implantable prosthetic valve.

Abstract: A two-stage or component-based valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve comprises a support structure that is deployed at a treatment site. The prosthetic valve further comprises a valve member configured to be quickly connected to the support structure. The support structure may take the form of a stent that is expanded at the site of a native valve. If desired, the native leaflets may remain and the stent may be used to hold the native valve open. In this case, the stent may be balloon expandable and configured to resist the powerful recoil force of the native leaflets. The support structure is provided with a coupling means for attachment to the valve member, thereby fixing the position of the valve member in the body. The valve member may be a non-expandable type, or may be expandable from a compressed state to an expanded state. The system is particularly suited for rapid deployment of heart valves in a conventional open-heart surgical environment.

Abstract: Embodiments of the present disclosure provide methods of loading a prosthetic heart valve within a delivery apparatus such that it can be used for delivery of the prosthetic heart valve to a native valve site via the human vasculature. The methods can include attaching the prosthetic heart valve to a valve-retaining mechanism at a distal end of the catheter and causing a torque shaft of the delivery apparatus to rotate relative to the catheter, wherein the torque shaft extends within the catheter and is coupled to the valve delivery sheath. Rotation of the torque shaft relative to the catheter can cause relative longitudinal movement between the valve sheath and the prosthetic heart valve such that the prosthetic heart valve is covered by the valve sheath.

Abstract: Embodiments of the present disclosure provide a prosthetic heart valve usable with a heart valve delivery apparatus for delivery of the prosthetic heart valve to a native valve site via the human vasculature. In one embodiment, a self-expanding valve comprises an expandable stent that is shaped to maintain the valve in the aortic annulus against axial without anchors or retaining devices that engage the surrounding tissue. The prosthetic heart valve can have a curved shape that tapers inwardly from the inflow end to a reduced diameter section, increases in diameter from the reduced diameter section to an intermediate section, and then tapers from the intermediate section to the outflow end

Abstract: A prosthetic heart valve can comprise a radially collapsible and expandable annular frame and a leaflet structure comprising a plurality of leaflets mounted within the frame. The frame can have commissure attachment portions that are configured to support the commissures of the leaflets in unique ways. For example, commissure attachment portions can include at least two struts defining a gap therebetween. Additionaly, angularly-spaced commissure attachment portions can comprise inner struts and outer struts. Adjacent side portions of leaflets can extend through a gap between the inner struts of a corresponding commissure attachment portion. Further features and arrangements are also possible.

Abstract: A method for delivering a self-expanding prosthetic heart valve comprises positioning the prosthetic heart valve in an annulus of a native heart valve while mounted in a radially compressed state in a delivery cylinder, the delivery cylinder coupled to a distal end portion of the torque shaft, and rotating a torque shaft coupled to the delivery cylinder. Rotating the torque shaft retracts the delivery cylinder, thereby exposing the prosthetic heart valve, allowing the prosthetic heart valve to self-expand in the native valve annulus. In some embodiments, the torque shaft is rotated by a motor disposed in a handle at a proximal end of the delivery device.
