INTRACARDIAC DEVICE TO CORRECT MITRAL REGURGITATION

摘要

A device structured to suppress mitral regurgitation by restricting prolapse of a mitral valve leaflet and including a base correspondingly dimensioned to the mitral valve and including a central portion, structured to allow blood flow there through and a peripheral portion or ring connected to the central portion in substantially surrounding relation thereto. An operative position of the base includes the central portion disposed in overlying, movement restricting relation to at least one of the valve leaflets and the ring concurrently anchored adjacent or directly to the native annulus of the mitral valve. The physical characteristics of the base facilitate its movement with and conformance to the mitral valve during diastole and systole cycles of the heart.

1. A device structured to restrict prolapse of a mitral valve leaflet into the left atrium of the heart, said device comprising:
a base including a peripheral portion and a central portion collectively disposed in an operative position relative to the mitral valve, said central portion connected to and surrounded by said peripheral portion, said central portion at least partially including a liquid permeable construction, said base movable with the mitral valve between an open orientation and a closed orientation of the mitral valve when in said operative position, and said operative position comprising said peripheral portion secured adjacent to a native annulus of the mitral valve and said central portion disposed in overlying, movement restricting relation to at least one mitral valve leaflet.
