Embodiment Construction

[0075] Figure 1-Figure 2 Two different views of a prosthetic valve 10 according to one embodiment are shown. The exemplified valve is adapted for implantation in the native aortic annulus, but in other embodiments it may be adapted for implantation in other native annulus of the heart. The valve 10 can have several main components: a stent or frame 12 , a valve structure 14 , and a skirt assembly 15 . The skirt assembly 15 may include an inner skirt 16 and optionally an outer skirt 18 .

[0076] The valve structure 14 (or leaflet structure) may include three leaflets 40 (although a greater or lesser number may be used) that together form a leaflet structure, which may be arranged to be collapsed in a tricuspid arrangement. Valve structure 14 is configured to allow blood to flow through prosthetic valve 10 in a direction from inlet end 48 of the prosthetic valve to outlet end 50 of the prosthetic valve, and to prevent blood from flowing in a direction from outlet end 50 to i...

Abstract

A method of assembling a prosthetic heart valve comprises securing a suture loop having at least first and second windings to an outflow edge portion of an inner skirt. The first and second windings are arranged in a repeating pattern of figure-eight shape curves and each winding has a plurality of first sections attached to the outflow edge portion of the inner skirt and a plurality of second sections unattached to the inner skirt. The inner skirt is placed inside of an annular frame and the second sections of the first and second windings are placed over apices of an outflow end of the frame such that the second sections of the first and second windings reside outside of the frame. The second sections of the windings are inserted inwardly through openings in the frame and attached to selected locations on the inner skirt.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 832,402, filed April 11, 2019, which is incorporated herein by reference. technical field [0003] The present disclosure relates to embodiments of prosthetic valves for implantation in body ducts, such as native heart valve annulus, and methods of assembling prosthetic heart valves. Background technique [0004] The human heart can suffer from various valve diseases. These valvular diseases can lead to severe heart dysfunction and eventually require replacement of the natural valve with an artificial valve. There are various known artificial valves and various known methods of implanting these artificial valves in the body. [0005] Various surgical techniques can be used to replace or repair diseased or damaged valves. Thousands of patients undergo surgery each year in which the defective natural heart valve is replaced with a prosthetic va...
