    Abstract: Embodiments of the present disclosure provide a prosthetic heart valve and a heart valve delivery apparatus for delivery of the prosthetic heart valve to a native valve site via the human vasculature. The delivery apparatus is particularly suited for advancing a prosthetic valve through the aorta (i.e., in a retrograde approach) for replacing a diseased native aortic valve. 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. A delivery apparatus for delivering s self-expanding prosthetic valve can be configured to allow controlled and precise deployment of the valve from a valve sheath so as to minimize or prevent jumping of the valve from the valve sheath.

    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: 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: An implantable prosthetic valve includes a frame and a leaflet structure positioned within the frame. The frame has a plurality of angled struts arranged to form a plurality of circumferentially extending rows of closed cells, including an uppermost row of closed cells defining an outflow end of the frame. The leaflet structure includes a plurality of leaflets, each having two opposing commissure portions and a lower edge portion coupled to the frame. Each commissure portion is paired with an adjacent commissure portion of an adjacent leaflet to form a commissure of the leaflet structure. The frame has a plurality of commissure support portions supporting respective commissures. The commissure support portions are positioned axially along the frame entirely within the uppermost row of closed cells. The commissure support portions are circumferentially spaced apart from each other by a plurality of closed cells of the uppermost row of closed cells.
