An intragastric anchor implant device is provided with a substantially rigid member having proximal and distal ends and atraumatic tips or features disposed near the proximal and distal ends. The atraumatic features prevent damage to the tissues of the stomach and the gastrointestinal track and may help to anchor the device in the stomach, while the substantially rigid member resists bending so as to engage a tissue of the stomach or the gastrointestinal tract to prevent passage through the stomach. The anchor implant device is coupled with a therapeutic device, typically a sleeve, such as an intestinal bypass sleeve. Ideally, the device includes a sliding seal to direct a flow of food particles from the stomach through the sleeve, so as to be useful in treating a disorder, including obesity and diabetes. Methods of deploying the anchor implant devices are also disclosed.
