Problems solved by technology

[0008] When the native anterior and posterior mitral leaflets are attached together at approximately the center of the valve (i.e., the A2 and P2 positions of the native leaflets), there may still be persistent leakage on one or both sides of the clip. leak, which causes regurgitation

Abstract

Apparatus for treating blood flow regurgitation through a native heart valve (16) includes a selective occlusion device sized and configured to be implanted in the native heart valve (16) and selectively operating with at least one of the first or second native leaflets (16a, 16b) to allow blood flow through the native heart valve (16) when the heart cycle is in diastole and reduce blood flow regurgitation through the native heart valve (16) when the heart cycle is in systole. A clip structure (50) is coupled with the selective occlusion device. The clip structure (50) is configured to be affixed to a margin of at least one of the first or second native leaflets (16a, 16b) to secure the selective occlusion device to the native heart valve (16).

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application Serial No. 62 / 627,894 (pending) filed February 8, 2018 and U.S. Provisional Patent Application Serial No. 62 / 671,077 (pending) filed May 14, 2018 ), the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates generally to ways of treating heart valves, and more particularly to ways of reducing regurgitation of blood flow through a heart valve, thereby improving the efficiency and function of the heart valve. Background technique [0004] Heart valve insufficiency, which has various forms and affects various heart valves such as the aortic, tricuspid, pulmonary, and mitral valves, has led to an expanding field of research and development aimed at improving heart valve function. Although any one or more of these natural heart valves may become damaged due to, for example, co...
