Patent ID: 8007507

Claim:
A delivery system for introducing an obesity device into a gastric lumen, comprising: an overtube including a proximal end, a distal end, a centrally disposed main lumen and a plurality of secondary lumens circumferentially disposed about the main lumen; an intragastric bag removably disposed within the main lumen of the overtube and being eversible therefrom; an attachment mechanism removably attaching a proximal end of the intragastric bag to the distal end of the overtube prior to the bag being released into the gastric lumen, the attachment mechanism comprising a plurality of retractable hooks extending through the plurality of secondary lumens, the plurality of hooks being adapted to secure the proximal end of the of the intragastric bag against the distal end of the overtube; an elongate strip of filler material adapted to be advanced through the main lumen of the overtube and into the intragastric bag; an endoscopic looping device being operably connected to at least one of the plurality of hooks, wherein the hooks are extending through the plurality of secondary lumens, the endoscopic looping device adapted to close the proximal end of the intragastric bag prior to being released into the gastric lumen, the endoscopic looping device being adapted to retain the strip of filler material within the intragastric bag; and a pusher rod having a proximal end and a distal end, the pusher rod being adapted to be advanced through the main lumen of the overtube, the pusher rod adapted for pushing the intragastric bag out of the main lumen and into the gastric lumen, and the pusher rod further adapted for pushing a the strip of filler material through the main lumen and into the intragastric bag.
