Methods and systems for tissue manipulation

1. An endoscopic treatment method, comprising:

introducing an endoscopic device into a lumen of a patient without creating an incision in the patient;

engaging a wall of the lumen with a tissue grasper;

moving the wall of the lumen with the tissue grasper to position the wail of the lumen around a flexible shaft of the endoscopic device to form a plication in the wall of the lumen;

anchoring the plication with an anchor object while the wall of the lumen is positioned around the shaft of the endoscopic device such that an open pocket is formed in the wall of the lumen;

with the wall of the lumen positioned around the shaft of the endoscopic device and with the plication anchored with the anchor object, moving a second portion of the wall of the lumen to position the second portion of the wall around the shaft of the endoscopic device to form a second plication in the wall of the lumen;

anchoring the second plication with a second anchor object such that a second open pocket is formed in the wall of the lumen; and

removing the shaft from the open pockets, thereby leaving behind the open pockets, the plication anchored with the anchor object, and the second plication anchored with the second anchor object.

2. The method of claim 1 , wherein the open pockets are aligned such that the open pockets form a hollow tube.

3. The method of claim 1 , wherein moving the second portion of the wall of the lumen comprises moving the second portion with a second tissue grasper.

4. The method of claim 1 , wherein the wall of the lumen remains positioned around the shaft of the endoscopic device and the second portion of the wall of the lumen remains positioned around the shaft of the endoscopic device when the second plication is anchored with the second anchor object.

5. The method of claim 2 , wherein the shaft has a substantially cylindrical shape such that the hollow tube has a substantially cylindrical shape.
