An inert adapter for supporting gastric devices. The adapter is connected to the inner lining of the stomach to encircle the esophageal sphincter and supports a treatment element. The treatment element is operated only after at least the healing period of the connection has passed. The adapter and the treatment element may be endoscopically inserted in a single action, and the activation of the treatment element may be carried out externally or internally by the dissolution of a dissolvable element. The adapter may support various treatment elements, such as an intake limiting pouch or an anti GERD device, and may additionally deliver drugs. Allowing a late activation of the device without additional intervention or even supervision simplifies gastric device applications and enhances their safety.
