Abstract

Method and apparatus for limiting absorption of food products in specific parts of the digestive system is presented. A gastrointestinal implant device is anchored in the pyloric portion of the gastrointestinal system and extends beyond the ligament of Treitz. All food exiting the stomach is funneled through the device. The gastrointestinal device includes an anchor for anchoring the device in the pyloric portion and a flexible sleeve that extents into the duodenum. The anchor is collapsible for endoscopic delivery and removal.

Claims

1. A method of treatment comprising the steps of:

anchoring a flexible sleeve within the gastrointestinal tract, the sleeve open at both ends and impregnated with a drug; and

extending the flexible sleeve into the intestine.

2. The method of claim 1, wherein the drug is an anti-hunger hormone.

3. The method of claim 1, wherein the drug is a drug that reduces inflammation.

4. The method of claim 2, anti-hunger hormone is peptide-YY.

5. The method of claim 2, wherein the anti-hunger hormone is selected from a group consisting of Ghrelin, Leptin, Glucagon-Like Peptide-1 (GLP-1), Cholecystokinin (CCK), and insulin.

6. The method of claim 3, wherein the drug that reduce inflammation is selected from a group consisting of aminosalicylates, corticosteroids, immune modifiers such as azathioprine and methotrexate, and antibiotics such as ampicillin and cipro.

7. A gastrointestinal implant device comprising:

a flexible sleeve, open at both ends to extend into the intestine, the flexible sleeve being impregnated with a drug; and

a collapsible anchor coupled to a proximal end of the sleeve to anchor the proximal portion of the sleeve in the digestive tract.

8. The implant of claim 7, wherein the drug is an anti-hunger hormone.

9. The implant of claim 7, wherein the drug is a drug that reduces inflammation.

10. The implant of claim 8 wherein the anti-hunger hormone is peptide-YY.

11. The method of claim 8, wherein the anti-hunger hormone is selected from a group consisting of Ghrelin, Leptin, Glucagon-Like Peptide-1 (GLP-1), Cholecystokinin (CCK), and insulin.

12. The implant of claim 9, wherein the drug that reduce inflammation is selected from a group consisting of aminosalicylates, corticosteroids, immune modifiers such as azathioprine and methotrexate, and antibiotics such as ampicillin and cipro.
