Described here are devices and methods for intussuscepting a portion of stomach tissue. Typically the intussusception is created at a position near, but distal to the gastroesophageal junction, and a pouch (1000) capable of storing a volume (from about 0 cc up to abou 100 cc) is created proximal the intussuscepted tissue (1002). In this way, the amount of food that may be ingested is reduced, helping to ameliorate GERD symptoms, and aiding in weight loss efforts Some of the devices described here include an expandable member and at least one suction inlet. In these devices, the expandable member is expanded to create a proximal cavity into which the stomach tissue is pulled (e.g., using suction), thereby creating the intussusception.
La présente invention concerne des dispositifs et des procédés destinés à l'intussusception d'une partie de tissu stomacal. Typiquement, l'intussusception est générée à une position proche, mais distale, de la jonction gastro-AEsophagienne, et une poche (1000) capable de stocker un volume (d'environ 0 cc à environ 100 cc) est créée de manière proximale par rapport au tissu invaginé (1002). De cette manière, la quantité de nourriture qui peut être ingérée est réduite, ce qui favorise l'amélioration des symptômes du GERD, et soutient les efforts de perte de poids. Certains des dispositifs décrits ici incluent un élément expansible et au moins un orifice d'aspiration. Dans lesdits dispositifs, l'élément expansible s'étend pour créer une cavité proximale dans laquelle le tissu stomacal est tiré (par exemple au moyen d'une aspiration), créant ainsi l'intussusception.
