  • Patent number: 8454683
    Abstract: A system for modifying a heart valve annulus includes a helically helical anchored annuloplasty device delivered to the annulus via an elongated delivery member. The helical anchors of the devices disclosed herein are rotated into the valve annulus along an anchor guide by using a driver that is movably disposed in the delivery member. A tether is disposed within an inner channel of the helical anchor and a locking device is used to secure the annuloplasty device after the valve annulus has been modified. The annuloplasty device can be delivered to the annulus using, traditional surgical approach or a minimally invasive or catheter based methods.

  • Patent number: 7699892
    Abstract: A method for modifying a heart valve annulus includes placing a purse string suture at a puncture site adjacent a heart valve, inserting at least one delivery member through the puncture site, positioning a distal end of the at least one delivery member adjacent a portion of a valve annulus, deploying an annuloplasty device carried within the at least one delivery member and implanting the annuloplasty device into the valve annulus. The method also includes reshaping the heart valve annulus after implantation of the at least one annuloplasty device.
