Methods and devices for folding and securing tissue
First Claim
1. A device for securing a fold of tissue in a medical procedure, the device comprising:
- a first arm; and
a second arm disposed substantially opposite to the first arm and having an end connected to an end of the first arm to define an opening to receive the fold of tissue, wherein the first and second arms are configured to secure to the tissue fold with the arms remaining exterior to an outer surface of the tissue fold.

Abstract
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.

8. A method of securing a tissue fold in an endoluminal medical procedure, the method comprising the steps of:
-
inserting an endoluminal device proximal to the tissue to be folded;
folding tissue to create a tissue fold;
inserting a tissue clip through the endoluminal device;
positioning the tissue clip such that the tissue fold is placed in an opening defined by the clip; and
engaging the fold with the tissue clip. - View Dependent Claims (9, 10, 11, 12, 13, 14, 16, 17, 18, 19, 20, 21, 22, 23, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64)

15. A working end of an endoluminal device for use in an endoluminal medical procedure, the working end of the device comprising:
a plurality of interconnected members having an expandable working surface area configured to engage with a portion of the body to perform the medical procedure.
-
24. A device for creating a tissue fold in an endoluminal medical procedure, the device including:
-
a tube defining a channel extending in a longitudinal direction from a proximal end to a distal end of the tube; and
an expandable arm pivotably disposed on the distal end of the tube, said arm configured to pivot between a position substantially along the longitudinal direction and a position angled to the longitudinal direction, the arm expandable from a retracted configuration to an expanded configuration.

-
65. A method for securing a tissue fold, comprising:
-
providing a mounting member having a peripheral surface and a plurality of first engagement portions disposed on the peripheral surface;
providing a plurality of tissue securing members adapted to engage the mounting member at the first engagement portions;
inserting the mounting member and tissue securing members endoluminally and proximal to the tissue fold to be secured;
positioning the tissue securing members on exterior surfaces of the tissue fold; and
engaging the tissue securing members with the first engagement portions to secure the tissue securing members in place with respect to the tissue fold and the mounting member. - View Dependent Claims (66, 67, 68, 69)

70. A device for securing tissue, comprising:
-
a tube defining a lumen therein and an opening proximate a distal end of the tube, said tube configured to accommodate suction through the lumen to draw tissue to be secured into the opening;
a holding member disposed in said lumen and configured to hold a tissue clip for securing the tissue; and
an inner member disposed in said lumen and configured to actuate relative to the tube between an open position and a closed position to open and close the tube opening, wherein the tissue clip is installed by the relative actuation. - View Dependent Claims (71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85)
