1. A device for suturing a heart valve, comprising:

  • an elongate body having a proximal end and a distal end configured to be delivered through a heart valve;

    a first needle operatively coupled to the elongate body near the distal end of the elongate body and configured to move between a retracted position and an advanced position; and

    a first arm attached to the elongate body near the distal end of the elongate body and disposed proximal to the first needle when the first needle is in the retracted position and the device is in a linear configuration, the first arm being configured to move between a retracted position and an extended position, the first arm comprising a suture mount configured to releasably retain a suture portion, the first arm in its extended position configured to position a leaflet of the valve between the first arm and the distal end of the elongate body;

    wherein the first needle is configured to move proximally from its retracted position to its advanced position to penetrate the valve leaflet and engage the suture portion retained in the suture mount when the first arm is in its extended position, and wherein the first needle with the engaged suture portion is configured to be retracted through the valve leaflet when the first needle is returned to its retracted position.
