Abstract:
1. A method for securing a tether during a mitral valve repair procedure comprising: securing one or more anchors coupled to the tether to internal ventricular wall tissue of a left ventricle at or adjacent to an intersection of a mitral valve leaflet and the ventricular wall tissue, such that the one or more anchors do not penetrate into a left atrium; advancing a tether-locking device in the left ventricle, the tether-locking device comprising an outer tubular body with a lumen therethrough, an aperture at the distal-most end of the tubular body for passage of the tether therethrough, and an inner locking member slidably retained within the lumen of the tubular body, wherein the locking device comprises an unlocked state wherein the tether is movable with respect to the locking device, and a locked state wherein the inner locking member secures at least a portion of the tether such that the tether exits the aperture at the distal-most end of the tubular body, the inner locking member is located proximally to the aperture and the tether bends against an external portion of the outer tubular body; and
