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.

1. A method for treating an overweight patient, comprising: endoscopically placing a dilating intra luminal device in a non-dilated state inside a stomach of the patient; andplacing a sensor and a controller inside the patient's body,the sensor configured to sense initiation of eating,the controller configured to automatically control, using a control algorithm and responsive to the initiation of eating, an extent of dilation of the intra luminal device and wirelessly transmit to outside the body of the patient information related to the sensing initiation of eating or the controlling the extent of dilation of the intra luminal device, the controller configured to move the intra luminal device from a non-dilated state to a dilated state at a speed, the speed being variable, the controller deciding the speed based on the control algorithm. 2. The method of claim 1, wherein the control algorithm is configurable from outside the body of the patient via wireless transmission. 3. The method of claim 1, wherein movement of the intra luminal device from the non-dilated state to the dilated state is initiated by the start of eating or other bodily functions related to eating. 4. The method of claim 1, wherein movement of the intra luminal device from the non-dilated state to the dilated state is initiated by a food hitting the intra luminal device. 5. The method of claim 1, wherein the sensor is configured to sense cessation of eating and the controller is configured to control the extent of dilation of the intra luminal device after the cessation of eating. 6. The method of claim 5, wherein the controller is configured to determine whether a delay should be introduced after the sensing cessation of eating and before the controlling the extent of dilation of the intra luminal device and introducing the delay when so determined. 7. The method of claim 1, wherein the controller is configured to store a plurality of event times associated with the controlling the extent of dilation of the intra luminal device including initiation of eating, cessation of eating, dilation of the intra luminal device and non-dilation of the intra luminal device. 8. The method of claim 1, wherein the controller is configured to decide a speed of non-dilation for the intra luminal device. 9. The method of claim 8, wherein the speed that the controller moves the intraluminal device from the non-dilated state to the dilated state and the speed of non-dilation can be altered by the controller based upon feedback. 10. The method of claim 1, wherein the control algorithm is customized for the particular patient. 11. An apparatus for treating an overweight patient, comprising: a dilating intra luminal device that is adapted to be endoscopically disposed inside a stomach;a sensor for sensing initiation of eating; anda controller, using a control algorithm and responsive to the sensor, for automatically controlling an extent of dilation of the intra luminal device and configured to wirelessly transmit to outside the body of the patient information related to the sensing initiation of eating or the controlling the extent of dilation of the intra luminal device, the controller configured to move the intra luminal device from a non-dilated state to a dilated state at a speed, the speed being variable, the controller deciding the speed based on the control algorithm. 12. The apparatus of claim 11, wherein the control algorithm is configurable from outside the body of the patient via wireless transmission. 13. The apparatus of claim 11, wherein movement of the intra luminal device from the non-dilated state to the dilated state is initiated by the start of eating or other bodily function related to eating. 14. The method of claim 11, wherein movement of the intra luminal device from the non-dilated state to the dilated state is initiated by a food hitting the intra luminal device. 15. The apparatus of claim 11, wherein the sensor is adapted for placement in the mouth of the patient. 16. The apparatus of claim 11, wherein the sensor is adapted for placement on an extremity of the patient. 17. The apparatus of claim 11, wherein the sensor is adapted for placement on the gastrointestinal tract of the patient. 18. The apparatus of claim 11, wherein the sensor is responsive to bodily actions selected from the group comprising receptive relaxation of the stomach, saliva secretion, chewing, swallowing, secretion of hormones, changes in blood glucose level, changes in heart rate variability or expansion of the stomach, or changes in electrical parameters of the stomach, including impedance. 19. The apparatus of claim 11, wherein the sensor is responsive to energy selected from the group comprising ultrasound, infrared, electrical, radio frequency, or magnetic. 20. The apparatus of claim 11, wherein the sensor is responsive to a measure of increased blood flow to the stomach, temperature change, change in local chemistry, or change in local environment. 21. The apparatus of claim 11, further comprising a memory for storing information related to operation of the intra luminal device. 22. The apparatus of claim 21, wherein the information includes dietary information. 23. The apparatus of claim 21, wherein the information includes blood sugar measurements. 24. The apparatus of claim 11, wherein the sensor is configured to sense cessation of eating and the controller is configured to control the extent of dilation of the intra luminal device in response to the sensing of cessation of eating. 25. The apparatus of claim 24, wherein the controller is configured to determine whether a delay should be introduced after cessation of eating and before the controlling the extent of dilation of the intra luminal device and introducing the delay when so determined. 26. The apparatus of claim 11, wherein the controller is configured to store a plurality of event times associated with the controlling the extent of dilation of the intra luminal device including initiation of eating, cessation of eating, dilation of the intra luminal device and non-dilation of the intra luminal device. 27. The apparatus of claim 11, wherein the controller is configured to decide a speed of non-dilation for the intra luminal device. 28. The apparatus of claim 27, wherein the controller is configured to alter the speed that the controller moves the intraluminal device from the non-dilated state to the dilated state, and the speed of non-dilation based upon feedback. 29. The apparatus of claim 11, wherein the control algorithm is customized for the particular patient.
