1. A method of securing tissue within a hollow body organ, comprising:

  • endoluminally advancing a tissue grasping tool into the hollow body organ;

    pivoting the tissue grasping tool about a fixed pivot joint connecting the grasping tool to an elongate member;

    reversibly engaging the tissue within the hollow body organ with a tissue engagement member adjacent to the tissue grasping tool;

    pulling the engaged tissue with the tissue engagement member;

    clamping the engaged tissue with the tissue grasping tool;

    after engaging the tissue and pulling the tissue, piercing through the engaged tissue with a needle of an anchor deployment assembly, the needle having a sharpened tip, with the needle separate from the tissue engagement member;

    deploying a distal tissue anchor through the needle on a distal side of the engaged tissue;

    retracting the needle to a proximal side of the engaged tissue;

    deploying a proximal tissue anchor through the needle on the proximal side of the engaged tissue, with a suture connecting the proximal and distal tissue anchors; and

    severing the suture adjacent to the proximal anchor using the sharpened tip of the needle, thereby releasing the proximal and distal anchors from the anchor deployment assembly.
