1. A system for creating and fixating a fold in the wall of a hollow organ by bringing multiple regions of the outer surface of the organ into apposition, comprising:

  • a first tube having a lumen, a proximal end and a distal end positionable within the organ;

    a second tube having a lumen, a proximal end and a distal end, the second tube configured to pass through the lumen of the first tube into the organ;

    a piercing element configured to pass through the lumen of the second tube to pierce the organ, position the distal end of the second tube outside of the organ, again pierce the organ, and position the distal end of the second tube back inside the organ;

    a first tissue anchor having a first state configured to pass through the lumen of the second tube and a second state configured for tissue fixation;

    a suture attached to the first tissue anchor;

    a second tissue anchor having a first state configured to pass through the lumen of the first tube and slideably engaged with the suture, and a second state configured to fixate tissue and lock onto the suture;

    a location indicator associated with the distal end of the second tube; and

    an optical receiver associated with the distal end of the first tube for identifying the location of the distal end of the second tube when it is outside the organ.
