    Abstract: Embodiments of a prosthetic heart valve are disclosed. An implantable prosthetic valve can include an annular frame having an inflow end, an outflow end and a central longitudinal axis extending from the inflow end to the outflow end. The valve can include a valvular structure including two or more leaflets, each of the two or more leaflets having a leaflet inflow edge positioned at least partially outside of the frame and a leaflet outflow edge positioned within the frame, wherein at least a portion of each of the leaflet inflow edges is unsupported by the frame.

    Abstract: Methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support member is positioned to at least partially surround the native leaflets of a valve. A locking member is used to couple both ends of the support member, forming a support band. An expandable prosthetic heart valve is delivered into the native heart valve and expanded while the expandable prosthetic valve is at least partially within the support band, thereby causing one or more of the native leaflets of the native heart valve to be frictionally secured between the support band and the expanded prosthetic heart valve.

    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: Disclosed herein are embodiments of a balloon shaped to have one or more enlarged regions to selectively increase expansion forces on an implant. For example, the balloon may have a central portion that is enlarged to exert more force on the center of a stent-mounted prosthetic heart valve. This overcomes the stent-mounted prosthetic heart valve's tendency to expand with flared ends. This forms a more cylindrical or barrel shaped stent frame during expansion of the balloon—reducing or eliminating the instance wherein the cylindrical stent frame has flared ends. Alternatively, the balloon may have conical flares placed to cause or enhance flared ends of the cylindrical implant to enhance its anchoring capabilities.

    Abstract: An implantable prosthetic valve can include a radially expandable and collapsible annular frame having an inflow end and an outflow end. A leaflet structure can be positioned within the frame. An annular inner skirt can be positioned around an inner surface of the frame, wherein the inner skirt includes an outflow edge portion secured to the frame and an inflow edge portion that wraps around the inflow end of the frame and extends at least partially along an outer surface of the frame, with the inflow edge portion being secured to the frame. An outer skirt can be positioned around the outer surface of the frame, wherein the outer skirt comprises an outflow edge portion secured to the frame and an inwardly folded inflow edge portion that is secured to the inflow edge portion of the inner skirt.

    Abstract: Prosthetic devices and frames for implantation at a cardiac valve annulus are provided that include an annular frame (having an inflow end and an outflow end) and a plurality of axial frame members that bridge two circumferentially extending rows of angled struts. The axial frame members can include a plurality of axially extending leaflet attachment members and a plurality of axial struts in a 1:1 ratio. Along each of the two rows, the frame can have at least three angled struts between adjacent axial frame members.
