1. Apparatus for forming a tissue fold in a tissue wall of a gastrointestinal lumen, comprising:

  • a catheter having a proximal region and a distal region, the catheter adapted to be inserted via a patient'"'"'s esophagus to position the distal region in the patient'"'"'s gastrointestinal lumen;

    a tissue grabbing assembly disposed at the distal region, the tissue grabbing assembly being configured to reversibly engage a tissue wall of the patient'"'"'s gastrointestinal lumen;

    a first flexible tube disposed on the distal region such that the distal end of the first flexible tube is at a location initially proximal of the tissue grabbing assembly; and

    an actuation mechanism for moving the tissue grabbing assembly to a tissue folding position proximal of the distal end of the first flexible tube to form a tissue fold, with the actuation mechanism including a pivot link attached to each of the tissue grabbing assembly and the first flexible tube and effecting a position of the tissue grabbing assembly relative to the distal end of the first flexible tube.
