Intragastric implant devices for obesity treatment are disclosed. The device is passive and does not autonomously change shape, but instead reacts to movement of the stomach to induce satiety. The device includes a series of connected, articulated clips that plicate the stomach wall nondestructively (no puncturing through the gastric wall) such that the overall volume of the stomach is reduced. Cam-shaped clamping surfaces prevent slippage of the stomach tissue from within the clips. Methods of implant are disclosed including delivering the device through a transoral delivery tube and advancing the device through the esophagus to be deployed within the stomach. Removal of the device occurs in the reverse.
