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 stomach 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 to the stomach and a flexible sleeve to limit absorption of nutrients in the duodenum. The anchor is collapsible for endoscopic delivery and removal.

Claims

1. A gastrointestinal implant device comprising:

a flexible sleeve, open at both ends, one foot to five feet in length to extend into the intestine and adapted to limit absorption of nutrients in the intestine, thin and conformable so that it collapses in the intestine to a small volume and unsupported at a distal end; and

an anchor comprising a network of struts, the network of struts comprising a plurality of diamond-shaped openings between the struts, the anchor being coupled to a proximal portion of the sleeve and configured to anchor the sleeve at or distal to the pylorus in the digestive system.

2. The gastrointestinal implant device of claim 1, wherein the anchor is configured to be retained distal to the pylorus.

3. The gastrointestinal implant device of claim 1, wherein the anchor is configured to be retained within the pyloric orifice.

4. The gastrointestinal implant device of claim 1, wherein the anchor is collapsible.

5. The gastrointestinal implant device of claim 1, wherein the sleeve is of a length that chyme exiting the stomach funneled through the proximal end of the sleeve exits the sleeve through the distal end below the ligament of Treitz.

6. The gastrointestinal implant device of claim 1, wherein the sleeve material has a coefficient of friction of less than 0.2.

7. The gastrointestinal implant device of claim 1, wherein the sleeve is formed of a fluoropolymer.

8. The gastrointestinal implant device of claim 7, wherein the sleeve is coated with a coat of silicone.

9. The gastrointestinal implant device of claim 7, wherein the sleeve is coated with a coat of polyurethane.

10. The gastrointestinal implant device of claim 1, wherein the sleeve is formed of polyethylene.

11. The gastrointestinal implant device of claim 1, wherein the distal end of the sleeve is directionally textured.

12. The gastrointestinal implant device of claim 1, wherein the sleeve causes enzymes secreted in the duodenum to pass through the duodenum outside the sleeve.

13. The gastrointestinal implant device of claim 1 in combination with a catheter to insert the flexible sleeve.

14. The gastrointestinal implant device of claim 1 in combination with a removal device to remove the flexible sleeve.
