Problems solved by technology

Although complete surgical correction of mitral regurgitation has been demonstrated surgically, mitral regurgitation is common after valvuloplasty repair due to continued dilatation or deformation of the left atrium causing further binding of the mitral valve leaflets. Massive recurrence (25%)

Embodiment Construction

[0074] The present invention relates generally to devices and methods for treating heart valve dysfunction, and more particularly, to a device and method for providing subvalve leaflet support and subvalve device support to passively help prevent or alleviate heart valve regurgitation. The present invention generally provides an annuloplasty ring system having an infra-annular, free-sided leaflets, and an infravalvular device support mechanism to prevent leaflet binding and regurgitation during systole. Advantageously, the present invention provides synchronized annular and subannular levels of cardiac remodeling of the heart valves (mitral and tricuspid) to correct and normalize the levels and angles of the leaflet seams, prevent leaflet binding and Eliminates the problem of valvular regurgitation recurring over time. Thus, the present invention provides treatment not only for valvular regurgitation, such as functional mitral regurgitation, but also for valvular regurgitation...

Abstract

An apparatus (10) is provided for treating regurgitation of blood flow through a diseased heart valve. The diseased heart valve includes an annulus, anterior and posterior valve leaflets, and a subvalvular apparatus. The apparatus includes a substantially annular support member (40) and at least one infra - annular support member (42) securely connected thereto. The substantially annular support member has at least a first intermediate portion, a second intermediate portion, and a posterior end portion extending between the first and second intermediate portions. The posterior end portion is dimensioned for attachment to a posterior portion of the annulus of the diseased heart valve. The at least one infra - annular support member is securely connected to the substantially annular support member at a first location. The at least one infra - annular support member is dimensioned to extend below at least one of the posterior and anterior valve leaflets and across or behind at least one subvalvular structure.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 61 / 429,543, filed January 4, 2011, the contents of which are hereby incorporated by reference. technical field [0003] The present invention relates generally to devices and methods for treating heart valve dysfunction, and more particularly, to a method for providing sub-valvular leaflet support and subvalvular device support to help prevent or relieve heart failure in a passive manner. Devices and methods for valvular regurgitation. Background technique [0004] The opening and closing of heart valves occurs primarily because of pressure differences. For example, the opening and closing of the mitral valve occurs because of a pressure difference between the left atrium and left ventricle. During diastole of the ventricles, the venous return of blood from the pulmonary veins into the left atrium causes the pressure in the left atrium t...
