摘要
A cardiac valve annulus may be constricted by using an apparatus to deliver a cord to the annulus, affixing the cord, and subsequently tightening that cord. In some embodiments, this apparatus includes an elongated core with a main channel, a set of first channels, and at least one second channel, all of which run through the core. The first channels accommodate pull wires for triggering the anchor launchers, and the second channels accommodate portions of the cord. Support arms extend distally beyond the core, and anchor launchers are mounted to each of these support arms. The support arms hold the distal ends of the anchor launchers at positions distributed about the annulus. The anchors are launched to affix the cord, and the cord is tightened in a subsequent procedure.
