Publication number: 20240024099Abstract: 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.Type: ApplicationFiled: August 16, 2023Publication date: January 25, 2024Applicant: EDWARDS LIFESCIENCES CORPORATIONInventors: Tamir S.

Patent number: 11793632Abstract: 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.Type: GrantFiled: July 18, 2019Date of Patent: October 24, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Tamir S.

Publication number: 20230263628Abstract: A device for crimping a radially expandable and collapsible prosthetic valve comprises a crimping loop having a first end portion, a second end portion, and a loop portion extending between the first and second end portions and defining an opening configured to receive the prosthetic valve. The crimping loop is movable between a first state in which the opening has a first diameter and a second state in which the opening has a second diameter smaller than the first diameter such that when the prosthetic valve is positioned within the loop portion, movement of the crimping loop from the first state to the second state is effective to reduce a diameter of the prosthetic valve. A method for crimping a prosthetic valve comprises reducing a diameter of an opening of a crimping loop, thereby radially compressing an at least partially expanded prosthetic valve disposed within the opening.Type: ApplicationFiled: April 25, 2023Publication date: August 24, 2023Inventors: David Maimon, Ron Sharoni, Tamir S.

Publication number: 20210386543Abstract: Embodiments of a radially collapsible and expandable prosthetic heart valve and method for crimping the prosthetic heart valve are disclosed. A method of radially compressing a prosthetic valve can include partially inserting the valve while in a radially expanded configuration into a crimping device comprising crimper jaws, wherein a portion of the valve comprising an outer skirt extends outside of the crimper jaws. The method can further include crimping the valve to a first partially collapsed configuration, further inserting the valve into the crimping device, such that the outer skirt is between the crimper jaws, and crimping the valve to a second partially collapsed configuration, wherein a diameter of the valve is smaller in the second partially collapsed configuration than in the first partially collapsed configuration.Type: ApplicationFiled: August 27, 2021Publication date: December 16, 2021Applicant: Edwards Lifesciences CorporationInventors: Tamir S.

Patent number: 11103345Abstract: Embodiments of a radially collapsible and expandable prosthetic heart valve are disclosed. The prosthetic valve can comprise an annular frame, leaflets, an inner skirt, and an outer skirt. The outer skirt can be secured to the outside of the inflow end portion of the frame, the outer skirt having longitudinal slack that buckles outward radially when the valve is in the expanded configuration and which lies flat when the valve is in the collapsed configuration. In some embodiments, the outer skirt is stiffer in the axial direction of the valve than in the circumferential direction of the valve. In additional embodiments, the outer skirt comprises a self-expandable fabric comprising fibers made of a shape memory material having a shape memory set to enhance the radially outward buckling of the outer skirt. Methods of crimping such valves to a collapsed or partially collapsed configuration are also disclosed.Type: GrantFiled: January 30, 2019Date of Patent: August 31, 2021Assignee: Edwards Lifesciences CorporationInventors: Tamir S.
