A delivery system (100) for introducing a bundled intragastric bag (130) into a gastric lumen (150) are described. The delivery system includes a pushing mechanism movable between an unexpanded and expanded configuration. The pushing mechanism (196) in its expanded configuration pushes each of the bundles (310) of the bag into the gastric lumen. A suture (170, 180) strand is periodically pulled during the procedure to help create doughnut- shaped bundles. Another suture strand extends between a proximal button and distal button of the deployed assembly to maintain the doughnut- shaped bundle structure.

La présente invention concerne un système de mise en place (100) permettant d'introduire un sac intragastrique (130) pourvu de faisceaux dans une lumière gastrique (150). Le système de mise en place comporte un mécanisme poussoir susceptible de passer d'une configuration non dilatée à une configuration dilatée. Lorsqu'il est dilaté, le mécanisme poussoir (196) pousse chacun des faisceaux (310) du sac dans la lumière gastrique. Un fil de suture (170, 180) est périodiquement tiré pendant la procédure pour favoriser la création de faisceaux en forme d'anneau. Un autre fil de suture s'étend entre un bouton proximal et un bouton distal de l'ensemble déployé pour maintenir la structure de faisceaux en forme d'anneau.
