    摘要: 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.

    摘要: An implantable prosthetic valve, according to one embodiment, comprises a radially collapsible and expandable frame and a leaflet structure supported within the frame. The leaflet structure can comprise a plurality of leaflets paired together at commissures. In one embodiment, the commissures can comprise leaflet tabs rolled into spirals around non-rigid reinforcing inserts. In another embodiment, the commissures can comprise a reinforcing sheet folded around leaflet tabs.

    摘要: A two-part implantable heart valve and procedure are disclosed that allow expansion and positioning of a first part of the implantable heart valve having a temporary or transient valvular structure. A second part of the implantable heart valve is deployed within the first part and attaches thereto. The valvular structure of the second part then acts to function as the heart valve replacement. A tool or system is provided for determining an adequate percutaneous heart valve size for a given stenotic valve. A balloon can be inflated inside the stenotic valve to a desired pressure. When this pressure is reached an angiographic image is taken and the balloon diameter is measured at a waist area created by contact between the balloon and the stenotic valve. The diameter represents the minimum percutaneous heart valve diameter to be implanted.
