An apparatus (100;1000) and method for gastric reduction is provided comprising a tissue gathering assembly (126; 1020) for applying a force to inner portions of a stomach to collapse the inner portions toward the tissue gathering assembly, and a suture assembly (154; 1070) moveably mounted to the tissue gathering assembly for advancing a suture (520; 1040) into the inner portions to form a gastric sleeve. The tissue gathering assembly may further comprise a vacuum shaft (136; 1160) having sections (1166) of apertures (138; 1168), wherein each section transmits a vacuum force through the apertures to gather a part of the inner portions of the stomach to form a channel that connects an upper pouch to a lower pouch of the stomach. The suture assembly may further comprise a rotatable helical suture for fastening the gathered inner portions to secure the gastric sleeve.

L'invention concerne un appareil et un procédé de réduction gastrique comprenant un ensemble de rassemblement de tissus pour appliquer une force sur des parties intérieures d'un estomac pour comprimer les parties intérieures en direction de l'ensemble de rassemblement de tissus, et un ensemble de suture monté de manière mobile sur l'ensemble de rassemblement de tissus pour faire progresser une suture dans les parties intérieures pour former un manchon gastrique. L'ensemble de rassemblement de tissus peut en outre comprendre un arbre sous vide ayant des tronçons d'ouverture, chaque tronçon transmettant une force d'aspiration à travers les ouvertures pour rassembler une partie des parties intérieures de l'estomac pour former un canal qui relie une poche supérieure à une poche inférieure de l'estomac. L'ensemble de suture peut en outre comprendre une suture hélicoïdale rotative pour fixer les parties intérieures rassemblées pour fixer le manchon gastrique.
