1. A method for treating overweight patients, comprising:
- applying a restrictive device to a part of a patient'"'"'s stomach; and
placing a sensor and a controller inside the patient'"'"'s body,the sensor configured to sense initiation of eating,the controller configured to automatically control the restrictive device in response to the initiation of eating to progressively control the restrictive device to mimic what occurs when a person begins to eat, the controller configured to move the restrictive device from a restricted state to a relaxed state at a speed of relaxation to increase an opening inside the patent'"'"'s stomach, the controller configured to alter the speed of relaxation,wherein most of the time the restrictive device is in the relaxed state and the stomach is at its natural state.

Abstract
An apparatus and method are disclosed for treating overweight and obese patients by applying a restrictive Artificial Gastric Valve (AGV) on part of the stomach. The apparatus includes a mechanism to control the opening of the AGV automatically on demand, dynamically and progressively. The controlled opening of the AGV inside the stomach controls and regulates the flow of food.

17. An apparatus for treating overweight patients, comprising:
-
a restrictive device which is adapted to be disposed on a part of a stomach; a sensor for sensing initiation of eating; and a control system, responsive to the sensor, for automatically controlling relaxation and restriction of the restrictive device, the control system configured to move the restrictive device from a relaxed state to a restricted state at a speed of restriction, the control system configured to alter the speed of restriction and to progressively control the restrictive device to mimic what occurs when a person begins to eat. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. A device that augments the natural response of a body to eating by reducing food intake, which comprises a sensor for sensing initiation of eating, an electronically controlled restrictive device, and a controller, that is responsive to the sensor, for progressively causing the electronically controlled restrictive device to physically restrict and relax part of a gastrointestinal (GI) tract, in order to mimic what occurs when a person begins to eat, and to control and regulate flow of food, as food is ingested, the controller configured to move the electronically controlled restrictive device from a restricted state to a relaxed state at a speed of relaxation and to alter the speed of relaxation.

44. A method for augmenting the natural response of a body to eating by reducing food intake, comprising:
-
applying a restrictive device to a part of a patient'"'"'s stomach; and placing a sensor and a controller inside the patient'"'"'s body, the sensor configured to sense initiation of eating, the controller configured to electronically control the restrictive device, and progressively cause the restrictive device to physically restrict and relax part of the gastrointestinal (GI) tract, in order to mimic what occurs when a person begins to eat, and to control and regulate the flow of food, as food is ingested, the controller configured to move the restrictive device from a relaxed state to a restricted state at a speed of restriction and to alter the speed of restriction.
