Abstract

Methods and devices for use in tissue approximation and fixation are described herein. The present invention provides, in part, methods and devices for acquiring tissue folds in a circumferential configuration within a hollow body organ, e.g., a stomach, positioning the tissue folds for affixing within a fixation zone of the stomach, preferably to create a pouch or partition below the esophagus, and fastening the tissue folds such that a tissue ring, or stomas, forms excluding the pouch from the greater stomach cavity. The present invention further provides for a liner or bypass conduit which is affixed at a proximal end either to the tissue ring or through some other fastening mechanism. The distal end of the conduit is left either unanchored or anchored within the intestinal tract. This bypass conduit also includes a fluid bypass conduit which allows the stomach and a portion of the intestinal tract to communicate.

Claims

1. A method of bypassing a hollow body organ, comprising:

forming a pouch from tissue of a hollow body organ by creating a narrowing incorporating at least two layers of tissue of the hollow body organ to enhance durability;

securing a proximal end of an artificial tubular member to the pouch formed within the hollow body organ; and

positioning a distal end of the tubular member such that the distal end is distal of the hollow body organ.

2. The method of claim 1 further comprising forming the pouch by creating a narrowing of the tissue within or partially within the hollow body organ prior to securing the proximal end.

3. The method of claim 1 further comprising forming the pouch by creating a narrowing of tissue proximal of or partially within the hollow body organ while securing the proximal end.

4. The method of claim 2 wherein the narrowing is created by a staple line constricting the hollow body organ.

5. The method of claim 1 wherein securing the proximal end further comprises securing the tubular member to the pouch created proximal of or partially within the hollow body organ.

6. The method of claim 4, wherein the staple line is formed circumferentially.

7. The method of claim 1, wherein the pouch has an opening having a diameter of about 1 cm between the pouch and the hollow body organ.

8. The method of claim 1, wherein the pouch defines a volume between 15 cc and 100 cc.

9. The method of claim 1, wherein the pouch defines a volume between 15 cc and 20 cc.

10. The method of claim 1, wherein the pouch has an orifice positioned distally of the gastoresophageal junction.

11. The method of claim 10, wherein the orifice is angled toward the lesser curve of a stomach.
