Abstract: Embodiments of a radially collapsible and expandable prosthetic heart valve are disclosed. A prosthetic heart valve includes a valve structure and a frame. The valve structure includes a plurality of leaflets, and the leaflets are configured to move from an open configuration to a closed configuration. The valve structure is coupled to the frame. The frame includes an inflow end, an outflow end, a longitudinal axis extending from the inflow end to the outflow end, and a plurality of struts forming a plurality of rows of cells. Each row of cells extends in a circumferential direction perpendicular to the longitudinal axis. Adjacent cells in a row of cell are coupled together at a junction of the struts defining the adjacent cells, and at least one junction in one row of cells has a shape that is different than at least one other junction of the one row of cells.

Abstract: An implantable prosthetic valve has an upper frame section and a lower frame section. The upper frame section has a plurality of struts and a first leaflet receiving surface at a lower portion of the upper frame section. The lower frame section has a second leaflet receiving surface at an upper portion of the lower frame section. An edge of a flexible leaflet is disposed between the first and second leaflet receiving surfaces to attach the leaflet to the upper and lower frame sections.

Abstract: A delivery assembly includes a prosthetic device, a catheter shaft, a release wire, a first line, and a second line. The prosthetic device has a first arm and a second arm. The release wire extends through the catheter shaft. The first line includes a first loop. The first line extends from the catheter shaft, through the first arm of the prosthetic device, and to the release wire, where the release wire extends through the first loop. The second line includes a second loop. The second line extends from the catheter shaft, through the second arm of the prosthetic device, and to the release wire, where the release wire extends through the second loop.

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 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: This application relates to methods, systems, and apparatus for replacing native heart valves with prosthetic heart valves and treating valvular insufficiency. In a representative embodiment, a support frame configured to be implanted in a heart valve comprises a main body formed by formed by a plurality of inner members forming an inner clover and a plurality of outer members forming an outer clover. The support frame can include gaps located between inner members of the plurality of inner members and outer members of the plurality of outer members. The inner clover can be radially inside the outer clover, and the outer clover can have larger dimensions than the inner clover. The support frames herein can be radially expandable and collapsible.

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.
