The present invention relates to devices, and methods for using the devices, to create and secure a tissue fold during an endoluminal medical procedure. The devices and methods may be used for folding and securing, for example, a fundus wall onto an esophagus wall or esophageal tissue in the region of the lower esophageal sphincter (LES) to reduce the diameter of the esophagus opening in that region. One aspect of the invention includes forming the tissue fold by closing a grasping arm that is pivotably connected to an overtube that has been positioned at the juncture of the fundus wall and esophagus wall. A further aspect of the invention includes tissue clips configured to be inserted and positioned through an endoluminal device.

1. A method of creating a tissue fold comprising: inserting an endoscope and a grasper-overtube through an esophagus and at least partially into a stomach cavity, the grasper-overtube including a tube, disposed radially outward and around the endoscope, and an arm movably mounted relative to the tub
1. A method of creating a tissue fold comprising: inserting an endoscope and a grasper-overtube through an esophagus and at least partially into a stomach cavity, the grasper-overtube including a tube, disposed radially outward and around the endoscope, and an arm movably mounted relative to the tube;positioning the arm of the grasper-overtube at a first position radially outward from the tube, forming a first angle between the arm of the grasper-overtube and the tube;establishing native tissue between the arm of the grasper-overtube and a portion of the tube; andpositioning the arm of the grasper-overtube at a second position radially outward from the tube, forming a second angle between the arm of the grasper-overtube and the tube, the second angle being smaller than the first angle;grasping the native tissue and forming the tissue fold;inserting a tissue fastener through a lumen of the tube and an opening at a distal end of the tube, the tissue fastener having a first arm and a second arm coupled to the first arm of the tissue fastener; andsecuring the tissue fold with the tissue fastener, the first arm of the tissue fastener engaging a first outer surface of the tissue fold and having a free end positioned on a first side of the tissue fold, and the second arm of the tissue fastener engaging a second outer surface of the tissue fold and having a free end positioned on a second side of the tissue fold opposite the first side of the tissue fold. 2. The method of claim 1, wherein the tissue fastener is a clip. 3. The method of claim 1, further including moving the grasper-overtube in a direction toward the opening of the esophagus in the stomach to establish the native tissue between the arm of the grasper-overtube and the tube. 4. The method of claim 1, further including positioning the arm of the grasper-overtube at the second position to clamp the tissue fold. 5. The method of claim 1, wherein the native tissue is part of any one of a fundus of the stomach or a lower esophageal sphincter. 6. The method of claim 1, further including rotating the grasper-overtube about a longitudinal axis of the endoscope. 7. The method of claim 1, further including visualizing the native tissue while positioning the arm of the grasper-overtube relative to the tube. 8. The method of claim 1, further including pivoting the arm of the grasper-overtube relative to the tube in a direction away from a longitudinal axis of the endoscope to form the first angle and pivoting the arm of the grasper-overtube in a direction toward the longitudinal axis of the endoscope to form the second angle. 9. The method of claim 1, wherein a distal portion of the tube is clear. 10. The method of claim 1, wherein the tissue fastener is a one-piece fastener. 11. A method of forming and securing a tissue fold with a tissue manipulating device having a tubular portion disposed radially outward relative to an endoscope and an arm movably mounted relative to the tubular portion, the method comprising: inserting the endoscope and the tissue manipulating device through an esophagus and at least partially into a stomach cavity;pivoting the arm of the tissue manipulating device from a first position generally aligned with the tubular portion to a second position to form an angle between the arm of the tissue manipulating device and the tubular portion;positioning native tissue between the arm of the tissue manipulating device and the tubular portion;pivoting the arm of the tissue manipulating device to decrease the angle between the arm of the tissue manipulating device and the tubular portion to grasp the native tissue and form the tissue fold; andsecuring the tissue fold with a one-piece fastener having a first arm and a second arm coupled to the first arm of the tissue fastener, the first arm of the tissue fastener engaging a first outer surface of the tissue fold and having a free end positioned on a first side of the tissue fold, and the second arm of the tissue fastener engaging a second outer surface of the tissue fold and having a free end positioned on a second side of the tissue fold opposite the first side of the tissue fold. 12. The method of claim 11, further including securing the tissue fold with two one-piece fasteners. 13. The method of claim 11, further including moving the tissue manipulating device in a direction toward the opening of the esophagus in the stomach to position the native tissue between the arm of the tissue manipulating device and the tubular portion. 14. The method of claim 11, wherein the native tissue is part of a lower esophageal sphincter. 15. The method of claim 11, further including pivoting the arm of the tissue manipulating device in a direction away from a longitudinal axis of the endoscope when pivoting the arm of the tissue manipulating device from the first position to the second position. 16. The method of claim 11, further including pivoting the arm of the tissue manipulating device in a direction toward a longitudinal axis of the endoscope when pivoting the arm of the tissue manipulating device to decrease the angle between the arm of the tissue manipulating device and the tubular portion and grasp the native tissue. 17. The method of claim 11, further comprising inserting the one-piece fastener through a lumen of the tubular portion and an opening at a distal end of the tubular portion. 18. The method of claim 11, wherein a distal portion of the tubular portion is clear.
