System for treating heart valve malfunction including mitral regurgitation

摘要

A system for treating heart valve malfunction specifically including mitral regurgitation including a positioning structure operative to assume both expanded and contracted orientations and a retaining assembly positioned and structured to operatively dispose the positioning structure in moveably supporting lifting and/or positioning relation to the ventricular wall portion of the heart. The retaining assembly and the positioning structure are cooperatively disposed and structured to accomplish a shape variance of the heart upon a lifting or positioning force being exerted thereon substantially concurrent to the positioning structure being disposed in the expanded orientation. The force exerted on the heart at least partially defines a shape variance thereof to the extent of positioning of the leaflets of the mitral valve into a closed orientation which restricts mitral regurgitation.

主权项

1. A system for treating heart valve malfunction including mitral regurgitation, said system comprising;
a positioning structure operative to assume an expanded orientation and a contracted orientation, a retaining assembly positioned and structured to dispose said positioning structure in moveably positioning relation to an exterior of a wall of a heart, said retaining assembly and a positioning member cooperatively disposed and structured to accomplish a shape variance of the heart, substantially concurrent to said expanded orientation of said positioning assembly, and said shape variance at least partially defining a position of a mitral valve into a predetermined orientation which restricts mitral regurgitation, wherein said retaining assembly comprises a retaining structure dimensioned and configured for disposition in at least partially covering relation to a biventricular mass of a myocardium, and wherein said retaining structure comprises an open mesh material including a plurality of strands disposed in at least partially spaced relation to one another, said strands collectively disposed in at least partially surrounding relation to the biventricular mass and concurrently in retaining relation to said positioning structure.
