dissecting tool through the abdominal wall comprises the steps of:

inserting a needle or a tubular instrument into the abdomen of the patient's body;

using the needle or tubular instrument to fill the patient's abdomen with gas;

placing at least two laparoscopic trocars in the patient's body;

inserting a camera through one of the laparoscopic trocars into the patient's

abdomen, inserting at least one dissecting tool through one of said at least two laparoscopic trocars; and wherein in the step of dissecting an area of the stomach, using said at least one dissecting tool inserted through at least one of said trocars.

3. The method according to claim 1 , further comprising affixing the device to the stomach fundus wall by providing sutures or staples.

4. The method according to claim 1 , further comprising affixing the stomach fundus wall, the movement restriction device, or the stomach fundus wall and the movement restriction device, to a lower part of the patient's esophagus by providing sutures or staples.

5. The method according to claim 1 , further comprising affixing the stomach fundus wall , the movement restriction device, or the stomach fundus wall and the movement restriction device, to the patient's diaphragm muscle or associated muscles.

6. The method according to claim 1 , further comprising providing an apparatus for regulating the movement restriction device and operating said apparatus to regulate the movement restriction device.

7. The method according to claim 6 , wherein the movement restriction device comprises a filling body, wherein regulation of the movement restriction device includes changing a volume of the filling body when implanted.

8. The method according to claim 7 , comprising providing a syringe for injecting a volume of fluid into the filling body.

9. The method according to claim 1 , comprising a step of creating a pouch and invaginating the movement restriction device in the pouch to thereby fully enclose the device in the pouch.

10. The method according to claim 1 , comprising a step of creating a pouch and invaginating the movement restriction device in the pouch wherein the step of creating a pouch and invaginating the movement restriction device in the pouch comprises invaginating the movement restriction device such that the movement restriction device is not fully enclosed in the pouch, wherein the pouch is at least partly open comprising at least one of the method steps of:

creating a pouch that exhibits only one opening, and

creating a pouch that exhibits two openings and extends non-circumferentially around the stomach.

11. The method according to claim 10 , wherein a volume of the pouch is more than 15 milliliters.

12. The method according to claim 1 , wherein the method step of placing the movement restriction device contacting the stomach fundus wall comprises:

placing the movement restriction device on an outside of the stomach fundus wall;

creating a pouch in the stomach fundus wall for the movement restriction device;

and

in-vaginating the movement restriction device in the pouch, such that the movement restriction device rests against the outside of the stomach fundus wall, by providing sutures or staples to the stomach fundus wall, thereby preventing the cardia from sliding through the patient's diaphragm opening into the patient's thorax, so as to maintain the pressure support from the patient's abdomen that supports the patient's cardia sphincter muscle.

13. A method of treating a reflux disease in a patient by implanting a movement restriction device that, when implanted in a patient, restricts the movement of a stomach notch in relation to a diaphragm muscle, thereby preventing a cardia from sliding up through a diaphragm hiatus opening, the method comprising the steps of:

creating a hole in a stomach;

introducing the movement restriction device though the hole in the stomach and into the stomach;

placing the movement restriction device on an inside of a stomach fundus wall;

creating a pouch on an outside of the stomach fundus wall for the movement restriction device placed on the inside of the stomach fundus wall, and

in-vaginating the movement restriction device in the pouch contacting an inner side of the stomach fundus wall, by providing sutures or staples to the stomach fundus wall, preventing the cardia from sliding through the patient's diaphragm opening into the patient's thorax, so as to maintain the supporting pressure from the patient's abdomen that supports the patient's cardia sphincter muscle.

14. The method according to claim 2 , further comprising affixing the device to the

stomach fundus wall by providing sutures or staples.

15. The method according to claim 2 , further comprising affixing the stomach fundus wall, the movement restriction device, or the stomach fundus wall and the movement restriction device, to a lower part of the patient's esophagus by providing sutures or staples.

16. The method according to claim 2 , further comprising affixing the stomach fundus wall, the movement restriction device, or the stomach fundus wall and the movement restriction device, to the patient's diaphragm muscle or associated muscles.

17. The method according to claim 2 , further comprising providing an apparatus for regulating the movement restriction device and operating said apparatus to regulate the movement restriction device.

18. The method according to claim 17 , wherein the movement restriction device comprises a filling body and wherein regulation of the movement restriction device includes changing a volume of the filling body when implanted.

19. The method according to claim 18 , further comprising providing a syringe, comprising a fluid for injection into the filling body, and injecting a volume of said fluid into the filling body.

20. The method of treating reflux disease according to claim 1 , wherein the step of affixing the device contacting the stomach fundus wall comprises the steps of:

using a first fixation device comprising a tissue growth promoting structure for attachment of the movement restriction device to the stomach wall, and

suturing the first fixation device to the stomach wall with a contact surface towards the stomach.

21. The method of treating reflux disease according to claim 20 , wherein the tissue growth promoting structure for attachment of the movement restriction device to the stomach wall, comprises a net and sutures or staples that attach the net to the fundus stomach wall, wherein the method further comprising the step of:

suturing or stapling the net to the fundus stomach wall, thereby allowing by the net in-growth of human tissue for holding the movement restriction device in place towards the stomach fundus wall.

22. The method of treating reflux disease according to claim 2 , wherein the step of affixing the device contacting the stomach fundus wall comprises the steps of:

using a first fixation device comprising a tissue growth promoting structure for attachment of the movement restriction device to the stomach wall, and

suturing the first fixation device to the stomach wall with a contact surface towards the stomach.

23. The method of treating reflux disease according to claim 22 , wherein the tissue growth promoting structure for attachment of the movement restriction device to the stomach wall, comprises a net and sutures or staples that attach the net to the fundus stomach wall, thereby allowing by the net in-growth of human tissue for holding the movement restriction device in place towards the stomach fundus wall.
