Method and device for use in endoscopic organ procedures
First Claim
1. A surgical method, comprising:
- transorally advancing a first conduit and a second conduit into a patient;
implanting the first conduit within the patient such that food in the esophagus can enter the first conduit, advance through a cannulated interior of the first conduit, and exit the first conduit into an intestine of the patient prior to contacting gastric fluid produced by a stomach of the patient; and
implanting the second conduit within the patient such that the gastric fluid can enter the second conduit, advance through a cannulated interior of the second conduit, and exit the second conduit into the intestine prior to contacting the food, a proximal end of the second conduit being distal of a proximal end of the first conduit.

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.

3. A surgical method, comprising:
-
transorally advancing into a patient a first conduit having a first inner lumen extending between proximal and distal ends thereof; positioning the proximal end of the first conduit at a first location proximal to an intestine of the patient; positioning the distal end of the first conduit within the intestine; attaching the proximal end of the first conduit at the first location such that food can pass directly from the esophagus into the first inner lumen of the first conduit through the proximal end of the first conduit, advance through the first inner lumen of the first conduit, and exit the first inner lumen through the distal end of the first conduit at the second location to pass directly into the intestine; transorally advancing into the patient a second conduit having a second inner lumen extending between proximal and distal ends thereof; positioning the proximal end of the second conduit distal to the proximal end of the first conduit; and positioning the distal end of the second conduit within the intestine distal to the distal end of the first conduit. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A surgical method, comprising:
-
transorally advancing into a patient a first conduit having a first inner lumen extending between proximal and distal ends thereof; positioning the distal end of the first conduit at a first location within an intestine of the patient; attaching the proximal end of the first conduit to the patient such that food can pass into the first inner lumen of the first conduit through the proximal end of the first conduit, advance through the first inner lumen of the first conduit, and exit the first inner lumen through the distal end of the first conduit at the first location to pass directly into the intestine; transorally advancing into the patient a second conduit having a second inner lumen extending between proximal and distal ends thereof; positioning the proximal end of the second conduit distal to the proximal end of the first conduit; and positioning the distal end of the second conduit within the intestine distal to a duodenal ampulla of the patient; and allowing biliary fluid exiting the duodenal ampulla to enter the second inner lumen of the second conduit such that the biliary fluid can exit the second inner lumen of the second conduit through the distal end of the second conduit. - View Dependent Claims (20, 21)
