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： 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.

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.

摘要： A prosthesic valve for implantation in a body duct that can cover a range of target sizes by a single device. The valve comprises of three main elements:1) a support cylindrical frame structure that can be collapsed to a small diameter for insertion into the body and that can expand to a large diameter when positioned in the target implantation site, the expansion of the frame being limited by the native valve diameter, which the valve is implanted within. In some cases this may be self-expandable;2) A frustoconical leaflet support frame that has an inflow side and an outflow side. The inflow side of the leaflet support frame is attached to the cylindrical frame and can be expanded along with the cylindrical frame to a range of diameters up to the diameter of the body duct, while the outflow side is limited in its opening diameter to a smaller constant diameter;3) Flexible leaflets are attached to the leaflet support frame to create a valve that allows flow from inflow to outflow, but prevents flow in the opposite direction.A delivery catheter dilates the valve while the frustoconical leaflet support system enables the valve to function (open and close) during the deployment process. Unlike prior prosthetic valves that only allow valve expansion, the valve of the invention may be collapsed if needed in order to re position or retrieve the valve.

摘要： 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.

摘要： An implantable prosthetic valve assembly having a support stent, or frame, having circumferential struts with multiple bends forming obtuse angles when the valve assembly is expanded to its functional size. The frame can be manufactured with one or more of the circumferential struts in a partially collapsed state and a flexible valve member can be mounted to the partially collapsed frame. The partially collapsed struts can be formed with multiple bends having angles selected to facilitate crimping of the frame to a profile suitable for percutaneous delivery. When the frame is expanded, the bends can expand to form obtuse angles, thereby enhancing the rigidity of the frame to better resist closing forces exerted on the valve assembly.
