Abstract

A method and device for performing endoluminal fundoplication are described. A device is inserted in the patient'"'"'s stomach through the esophagus, including an unit adapted to grasp and pull a portion of the gastroesophageal junction into the stomach, and an unit adapted to move a portion of the fundus towards the esophagus. The device also can place fasteners to hold the gastric wall and the esophageal wall secured together, thus forming a valve between esophagus and stomach. An adhesive compound can be used to stabilize the juncture of the two walls.

Claims

1. A device for performing endoluminal fundoplication of a patient'"'"'s esophagus and stomach, comprising:

a flexible tube having a distal end adapted for insertion in the stomach through the esophagus;

a grasper disposed adjacent the distal end of the flexible tube and configured to grasp a selected portion of an esophageal wall;

a tissue displacement device disposed adjacent the distal end of the flexible tube and configured to press a fundus wall of the stomach towards the esophageal wall, so as to form an intussusception of the esophagus into the stomach; and

a fastening device configured to pass through a lumen of the flexible tube relative to the tissue displacement device and configured to insert a fastener through the intussusception after the intussusception is formed so as to maintain the esophageal wall and the fundus wall adjacent to one another.

2. The device of claim 1, further comprising an injector configured to inject one of an adhesive agent and a sclerosant agent between the fundus wall and the esophageal wall.

3. The device of claim 1, wherein the flexible tube comprises an overtube having at least one lumen for accommodating at least one of an endoscope and the tissue displacement device.

4. The device of claim 1, further comprising an endoscope.

5. The device of claim 1, wherein the grasper is configured to pull the grasped portion of the esophageal wall into the stomach.

6. The device of claim 1, wherein the fastening device includes a hypotube configured to extend across the intussusception.

7. The device of claim 1, wherein the fastener includes a distal end and a proximal end, and at least one of the distal and proximal ends includes a deformable member.

8. A device for performing endoluminal fundoplication of a patient'"'"'s esophagus and stomach, comprising:

a grasper configured to grasp a selected portion of an esophageal wall;

a tissue displacement device configured to press a fundus wall of the stomach towards the esophageal wall, so as to form an intussusception;

a fastener; and

a fastening device configured to insert the fastener through the intussusception after the intussusception is formed so as to maintain the esophageal wall and the fundus wall adjacent to one another, wherein the fastener includes a distal end and a proximal end, and at least one of the distal and proximal ends includes an inflatable member.
