Abstract:
1. A system for altering a mitral valve annulus comprising: an elongated tension member having a first end and a second end; a plurality of helical anchors, each helical anchor having a plurality of coils, and a distal end and a proximal end, the distal end of each helical anchor having a sharpened tip portion, and the plurality of coils of each helical anchor defining an inner channel through the center of the coils along a length of the helical anchors, the plurality of coils being operable to rotate the helical anchor into the annulus when the helical anchor is rotated about the inner channel; and at least one elongated tubular delivery member having a distal end, a proximal end, and a lumen communicating along the length of the tubular delivery member; wherein when the system is delivered proximate a mitral valve annulus, the helical anchors are alternately deployed on the anterior and posterior portions of the annulus with a portion of the elongated tension member being disposed through each of the inner channels of the helical anchors such that the elongated tension member defines a trans-leaflet portion that extends between one of the plurality of helical anchors deployed on one of the anterior or posterior sides of the annulus and an opposing one of the plurality of helical anchors deployed on the opposite side of the annulus; and at least one locking device disposed on the first end of the elongated tension member adjacent one of the plurality of helical anchors and sized such that it cannot pass through the inner channel of the adjacent helical anchor, wherein the at least one locking device includes,
