摘要：Devices and methods used in termination of a tissue tightening procedure aredescribed. Termination includes the cinching of a tether to tighten the tissue, locking thetether to maintain tension, and cutting excess tether. In procedures involving anchorssecured to the tissue, the tether is coupled to the anchors and the tissue is tightened via
tension applied to the anchors by cinching the tether. In general, the devices andmethods can be used in minimally invasive surgical procedures, and can be appliedthrough small incisions or intravascularly. A method for tightening tissue by fixedlycoupling a first anchor to a tether and slidably coupling a second anchor to the tether,securing both anchors to the tissue, applying tension to the tether intravascularly, fixedlycoupling the tether to the second anchor, and cutting the tether is described. The tissueto be tightened can comprise heart tissue, in particular heart valve annulus tissue. Variousdevices and methods for locking the tether in place and cutting excess tether aredescribed.
