1. A delivery system for placing a gastrointestinal implant device in a body comprising:
- an outer sheath to store therewithin a proximal portion of the gastrointestinal implant device, the proximal portion of the gastrointestinal implant device including a self-expanding sleeve anchor to anchor the device, the outer sheath moveable relative to the sleeve anchor to release the sleeve anchor from within the outer sheath;
an inner sheath within the outer sheath, the inner sheath defining a lumen and extending distally beyond the outer sheath;
a moveable element moveable within the lumen of the inner sheath to secure a distal end of a sleeve to the inner sheath, the sleeve coupled at its proximal end to the sleeve anchor; and
a sleeve release mechanism coupled to the moveable element to release the distal end of the sleeve.

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.

13. A delivery system for placing a gastrointestinal implant device in a body comprising:
-
an outer sheath in a proximal portion of the delivery system to store therewithin a proximal portion of the gastrointestinal implant device, the proximal portion of the gastrointestinal implant device including a self-expanding sleeve anchor to anchor the device, the outer sheath moveable relative to the sleeve anchor to release the sleeve anchor from within the outer sheath; an inner sheath within the outer sheath, the inner sheath extending beyond the outer sheath toward a distal end of the delivery system, a first lumen within the inner sheath to pass the outer sheath over a guidewire and a second lumen within the inner sheath to move a sleeve retention wire to secure a distal end of a sleeve coupled to the sleeve anchor to the inner sheath by exiting the second lumen of the inner sheath and piercing the distal end of the sleeve; and a sleeve release mechanism coupled to the moveable element to release the distal end of the sleeve. - View Dependent Claims (14, 15)

19. A delivery system for placing a gastrointestinal implant device in a body comprising:
-
a gastrointestinal implant device comprising a self expanding sleeve anchor and a sleeve coupled at its proximal end to the sleeve anchor; an outer sheath storing the self-expanding sleeve anchor in a compressed state within the outer sheath, the outer sheath moveable relative to the sleeve anchor to release the sleeve anchor from within the outer sheath to radially expand; an inner sheath within the outer sheath, the inner sheath defining a lumen and extending distally beyond the outer sheath; a moveable element moveable within the lumen of the inner sheath and securing a distal end of the sleeve to the inner sheath; and a sleeve release mechanism coupled to the moveable element to move the moveable element and thus release the distal end of the sleeve. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
