Intestinal sleeve
A gastrointestinal implant device is anchored in the duodenum and extends beyond the ligament of Treitz. All food exiting the stomach is funneled through the device. The gastrointestinal device includes an anchor for attaching the device to the duodenum and an unsupported flexible sleeve. The anchor can include a stent and/or a wave anchor and is collapsible for catheter-based delivery and removal.
1. A gastrointestinal implant device comprising:
a flexible sleeve configured to carry chyme from a proximal end of the sleeve to a distal end of the sleeve and adapted to extend into the duodenum; and
a collapsible self-expanding anchor coupled to the proximal end of the sleeve and adapted to be retained entirely within the duodenal bulb, the anchor having a relaxed diameter of at least about 40 millimeters.
2. The gastrointestinal implant device of claim 1 , wherein the anchor is attached to the surrounding anatomy with a mechanical fastener.
3. The gastrointestinal implant device of claim 2 , wherein the mechanical fastener is a suture.
4. The gastrointestinal implant device of claim 2 , wherein the mechanical fastener is a surgical staple.
5. The gastrointestinal implant device of claim 2 , wherein the mechanical fastener is a barb.
6. The gastrointestinal implant device of claim 5 , wherein the barb is bi-directional.
7. The gastrointestinal implant device of claim 1 , wherein the anchor is attached to the surrounding anatomy with a chemical fastener.
8. The gastrointestinal implant device of claim 7 , wherein the chemical fastener is a surgical adhesive.
9. The gastrointestinal implant device of claim 1 , wherein the sleeve comprises an anti-buckling mechanism extending along a length of the sleeve.
10. The gastrointestinal implant device of claim 1 , wherein the sleeve is impregnated with a drug that reduces hunger.
11. The gastrointestinal implant device of claim 10 , wherein the drug that reduces hunger is selected from the group consisting of Leptin, Glucagon-Like Peptide-1 (GLP-1), Cholecystokinin (CCK), peptide YY (PYY), insulin, and ghrelin.
12. The gastrointestinal implant device of claim 1 , wherein the sleeve is impregnated with a drug that reduces inflammation.
13. The gastrointestinal implant device of claim 12 , wherein the drug that reduces inflammation is selected from the group consisting of aminosalicylates, corticosteroids, immune modifiers, and antibiotics.
14. The gastrointestinal implant device of claim 1 , wherein a plurality of distal sections of the sleeve are coated to form a plurality of dissolvable pills.
15. The gastrointestinal implant device of claim 14 , wherein the dissolvable pills are configured to dissolve at different times.
16. The gastrointestinal implant device of claim 14 , wherein the dissolvable pills have a biodegradable coating.
17. The gastrointestinal implant device of claim 16 , wherein the biodegradable coating comprises polyethylene glycol.
18. The gastrointestinal implant device of claim 17 , wherein the biodegradable coating comprises polylactic acid.
