1. Apparatus for securing a tissue fold within a patient, the apparatus comprising:

  • a plication apparatus having a distal region adapted to engage a tissue fold within a patient; and

    an anchor assembly having proximal and distal anchors connected by a suture, said suture having a proximal end and a distal end, said anchor assembly being adapted for adjustment of the length of suture disposed between the proximal and distal anchors while the anchor assembly is disposed across the tissue fold;

    an anchor delivery system adapted to deploy and secure the anchor assembly across the tissue fold, said anchor delivery system comprising a flexible delivery tube having a lumen, and a hollow needle disposed within the lumen;

    wherein the anchor assembly passes through the hollow needle during delivery;

    wherein the anchor delivery system further comprises a trap mechanism located substantially within a distal region of said anchor delivery system, said trap mechanism being adapted to reversibly trap the suture at or near its proximal end to facilitate adjustment of the length of suture disposed between the proximal and distal anchors, and wherein the trap mechanism is adapted to release the suture after the length of suture has been adjusted.
