DEVICE AND METHOD OF TREATING HEART VALVE MALFUNCTION

摘要

An assembly and method for treating heart valve malfunction typically including treating of mitral regurgitation wherein an instrument assembly includes an elongated chord movably disposed within an introductory sheath and including an anchor secured to a distal end thereof. An attendant method includes concurrently introducing the sheath and the chord into the heart chamber through an exterior wall and penetrating and passing the sheath and the chord through the anterior mitral valve leaflet. The sheath and the chord are then extended transversely across the heart chamber and the distal end of the chord is anchored to an opposing portion of the heart wall. The sheath is then withdrawn back along the length of the anchored chord and through the anterior mitral valve leaflet and a securing member connects the proximal end of the chord to the valve leaflet. The chord is secured between the valve leaflet and the opposing heart wall under sufficient tension to maintain an intended positioning of the valve leaflet to overcome mitral regurgitation.
