Abstract: Delivery assemblies including a prosthetic heart valve and a delivery apparatus are disclosed. The prosthetic heart valve includes a frame having posts extending from a terminal outflow end of the frame and a valve structure disposed within the frame. The delivery apparatus includes an inner shaft including a valve connection portion having recesses configured to receive the posts of the frame of the prosthetic heart valve, an outer shaft including a valve sheath for retaining the prosthetic valve in a radially compressed state and retaining the posts within the recesses, and a handle including a control knob for moving the valve sheath proximally and distally relative to the handle. The control knob is seated within the handle housing such that the housing partially covers a circumferentially extending outer surface of the control knob.

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 prosthetic heart valve comprises a radially collapsible and expandable annular frame and a leaflet structure comprising three leaflets. Each leaflet has an upper edge portion, a curved lower edge portion and two side flaps, wherein each side flap is connected to an adjacent side flap of another leaflet to form commissures of the leaflet structure, with each commissure being attached to the frame. An annular inner sleeve comprises three U-shaped portions positioned along the curved lower edge portions of the leaflets. An annular outer sleeve extends around are outer surface of the frame, wherein the outer sleeve is made of pericardium. The frame is made of Nitinol and the prosthetic valve can be radially crimped to a radially collapsed configuration inside a sheath for delivery into a patient's body and self-expand to a radially expanded configuration when released from the sheath inside the patient's body.

Abstract: Prosthetic heart valves are described. Prosthetic heart valves can include radially expandable and compressible inner and outer metal frames. The inner frame can be disposed within a lumen of the outer frame and can be coupled to the outer frame. An outflow end of the inner frame can be coupled to and/or located at an outflow end of the outer frame. An end portion of the inner frame can be spaced radially inwardly from an inner surface of the outer frame, such that a radial gap exists between the inner surface of the outer frame and an outer surface of the inner frame. Prosthetic heart valves can further include a plurality of leaflets disposed within and supported by the inner frame, such as by commissure posts of the inner frame.

Abstract: An implantable prosthetic valve includes a radially collapsible and expandable annular frame having three commissure attachment posts and four rows of circumferential struts. The rows include a first row, a second row downstream of the first row, a third row downstream of the second row, and a fourth row downstream of the third row and defining an outflow end of the frame. Each row of circumferential struts includes angled struts arranged in a zig-zag pattern. A leaflet structure includes three leaflets forming three commissures, each commissure being connected to one of the commissure attachment posts only at locations along the commissure attachment posts between a first plane that is perpendicular to a longitudinal axis of the frame and intersects crowns of the third row of struts and a second plane that is perpendicular to the longitudinal axis and intersects crowns of the fourth row of struts.

Abstract: A method of implanting a prosthetic heart valve within a patient can comprise inserting a distal end portion of a delivery apparatus and a prosthetic heart valve into the patient and advancing the prosthetic heart valve to a deployment location within the heart of the patient and inflating one or more of a plurality of differently-sized balloons in a balloon-assembly on the distal end portion of the delivery apparatus. The prosthetic heart valve can be mounted on the balloon assembly in a crimped state and the inflating of the one or more of the plurality of differently-sized balloons can expand the prosthetic heart valve from the crimped state to a radially expanded state having a non-cylindrical shape.

Abstract: An assembly for replacement of a native aortic heart valve includes a radially collapsible prosthetic heart valve and a delivery apparatus. The prosthetic heart valve includes an annular frame with attachment posts, wherein each of the posts has an axial post portion and a transverse post portion having a greater circumferential dimension than the axial post portion. The delivery apparatus includes an inner shaft with a valve connection portion for releasably coupling to the attachment posts and an outer shaft having a sheath for maintaining the prosthetic heart valve in a radially compressed state. Rotation of a control knob on a handle causes the sheath to retract for uncovering a portion of the prosthetic heart valve. Further rotation of the control knob allows the posts to decouple from the delivery apparatus such that the prosthetic heart valve self-expands to a fully expanded state.
