Abstract

A method for treating a patient includes creating at least one incision to gain access to an peritoneal cavity, performing a gastric volume reduction procedure and introducing a device to prevent gastric contents from interacting with at least a portion of the duodenum.

First claim

The invention claimed is:

1. A method for treating a patient, comprising:
creating at least one incision to gain access to a peritoneal cavity;
performing a gastric volume reduction procedure;
introducing a duodenal sleeve for transporting chyme exiting the stomach to prevent gastric contents in the form of chyme from interacting with at least a portion of a duodenum, the duodenal sleeve including a proximal opening and a distal opening, the step of introducing further includes anchoring the proximal opening to, or distal to, muscle in a pyloric portion of the stomach; and
directing the chyme leaving the stomach inside the duodenal sleeve and bypassing the duodenum such that there is no mixing of chyme with bile until the chyme reaches a jejunum.

2. The method according to claim 1 , wherein the duodenal sleeve includes a sleeve and a proximal end having a self-expanding stent.

3. The method according to claim 2 , wherein the sleeve is from about one foot to about five feet in length.

4. The method according to claim 1 , wherein the step of performing a gastric volume reduction procedure includes forming at least one fold of gastric tissue and securing the fold with a fastener.

5. The method according to claim 4 , wherein the fold is on an exterior surface of a gastric cavity apposing exterior, serosal layers of the gastric cavity to form the fold.

6. The method according to claim 5 , the fold has serosa-to-serosa contact substantially along its entire length.

7. The method according to claim 4 , wherein the fold is formed in an anterior cavity wall.

8. The method according to claim 4 , wherein the fastener is a tissue anchoring device.

9. The method according to claim 8 , wherein the tissue anchoring device is a T-tag anchor.

10. The method according to claim 4 , wherein the step of folding includes physically abrading, or thermally or electrically damaging the gastric tissue.

11. The method according to claim 4 , wherein the fold is formed about a greater curvature of a stomach.

12. The method according to claim 4 , the fastener is a staple.

13. A method for treating a patient comprising;
creating at least one incision to gain access to a peritoneal cavity;
reducing the capacity of the gastric cavity;
introducing a duodenal sleeve for transporting chyme exiting the stomach to prevent gastric contents in the form of chyme from interacting with at least a portion of a duodenum, the duodenal sleeve including a proximal end and a distal end;
anchoring the proximal end of the duodenal sleeve in the vicinity of a pylorus of the stomach;
extending the distal end of the duodenal sleeve to such that a distal opening at the distal end of the duodenal sleeve extends distally beyond the duodenum; and
directing the chyme leaving the stomach inside the duodenal sleeve and bypassing the duodenum such that there is no mixing of chyme with bile until the chyme reaches a jejunum.
