Transoral endoscopically guided stapling system (TOGA) for the creation of an endoscopic vertical gastroplasty, (a) The TOGA sleeve stapler that is used to create a gastric sleeve with a luminal diameter of approximately 20 mm parallel to the lesser curvature of the stomach, and the TOGA restrictor used to staple gastric folds together and restrict the distal end of the sleeve to approximately 12 mm. (b) The TOGA sleeve stapler with the extendable wire fully deployed for optimal alignment of the stapler, and a diagram showing the TOGA restrictor in place. (c) Radiographic and endoscopic views of the vertical gastroplasty created by the TOGA system. (Reprinted with permission from Deviere et al. [2008].)
