CA 2559206

Devices and methods for tissue acquisition and fixation, or gastroplasty, are described. Generally, the devices of the system may be advanced in a minimally invasive manner within a patient's body, e.g., transorally, endoscopically, percutaneously, etc., to create one or several divisions or plications within the hollow body organ. Such divisions or plications can form restrictive barriers within a organ, or can be placed to form a pouch, or gastric lumen, smaller than the remaining stomach volume to essentially act as the active stomach such as the pouch resulting from a surgical Roux-En-Y gastric bypass procedure. Moreover, the system is configured such that once acquisition of the tissue by the gastroplasty device is accomplished, any manipulation of the acquired tissue is unnecessary as the device is able to automatically configure the acquired tissue into a desired configuration.

La présente invention concerne des dispositifs et procédés destinés à l'acquisition et la fixation de tissus (ou gastroplastie). D'une manière générale, les dispositifs du système peuvent être avancés de manière peu invasive à l'intérieur du corps d'un patient, par exemple, de façon trans-orale, endoscopique, percutanée, etc., de manière à créer une ou plusieurs divisions ou plications à l'intérieur d'un organe de corps creux. Ces divisions ou plications peuvent former des barrières restrictives à l'intérieur d'un organe ou peuvent être placées de manière à former une poche ou une lumière gastrique plus petite que le volume d'estomac restant pour fonctionner sensiblement comme un estomac actif, comme, par exemple, lors d'une opération de dérivation gastrique chirurgicale de type Roux-En-Y. En outre, le système est configuré de façon que l'acquisition du tissu par le dispositif de gastroplastie soit accomplie; aucune manipulation du tissu acquis n'est dès lors nécessaire car le dispositif est capable de configurer automatiquement le tissu acquis pour le mettre dans une configuration désirée.
