Method and instruments for treating GERD

1. 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 the stomach notch in relation to the diaphragm muscle, thereby preventing the cardia from sliding up through the diaphragm hiatus opening, the method comprising the steps of:

inserting a needle or a tube like instrument into the abdomen of the patient's body; using the needle or tube like 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;

dissecting an area of the stomach;

introducing the movement restriction device into the abdominal cavity;

placing the movement restriction device on the 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 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.

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

3. The method according to claim 1 , further comprising affixing the stomach fundus wall to the lower part of the patient's esophagus by providing sutures or staples.

4. The method according to claim 1 , further comprising affixing the stomach fundus wall to the patient's diaphragm muscle or associated muscles.

5. The method according to claim 1 , further comprising providing an apparatus for regulating the movement restriction device from the outside of the patient's body; and operating said apparatus to regulate the movement restriction device.

6. The method according to claim 5 , wherein the movement restriction device comprises a filling body, wherein regulation of the movement restriction device includes changing the volume of the filling body when implanted.

7. The method according to claim 6 , comprising providing an injection type syringe comprising a fluid for injection into a the filling body; and

injecting volume of fluid into the filling body.

8. The method according to claim 1 , wherein the step of crating a pouch and invaginating the movement restriction device in the pouch, comprises fully enclosing the device in the pouch.

9. The method according to claim 1 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.

10. The method according to claim 9 , wherein the step of creating a pouch and invaginating the movement restriction device in the pouch comprises creating a pouch that exhibits only one opening.

11. The method according to claim 9 , wherein the steps of creating a pouch and invaginating the movement restriction device in the pouch comprises creating a pouch that exhibits two openings and extends non-circumferentially around the stomach.

12. The method according to claim 1 , wherein the volume of the pouch is more than 15 milliliters.

13. The method of treating reflux disease according to claim 1 , wherein the step of in-vaginating the movement restriction device in the pouch, comprises:

introducing an injecting member comprising an injectable filling material; and

injecting the filling material into the pouch, thereby creating a filling body that fills a volume in the created pouch, 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.

14. 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 the stomach notch in relation to the diaphragm muscle preventing the cardia to slide up through the diaphragm hiatus opening, the method comprising the steps of:

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

using the needle or tube like 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;

dissecting an area of the stomach;

creating a hole in the stomach;

introducing the movement restriction a device into the abdominal cavity;

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

placing the device on the inside of the stomach fundus wall;

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

in-vaginating the movement restriction device in the pouch 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.

15. The method according to claim 14 , further comprising affixing the movement restriction device to the stomach fundus wall by providing sutures or staples.

16. The method according to claim 14 , further comprising affixing the stomach fundus wall to the lower part of the patient's esophagus by providing sutures or staples.

17. The method according to claim 14 , further comprising affixing the stomach fundus wall to the patient's diaphragm muscle or associated muscles.

18. The method according to claim 14 , further comprising providing an apparatus for regulating the movement restriction device from the outside of the patient's body; and operating said apparatus to regulate the movement restriction device.

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

20. The method according to claim 19 , comprising providing an injection type syringe comprising a fluid for injection into the filling body; and

injecting volume of fluid into the filling body.

21. The method according to claim 14 , wherein the step of creating a pouch and invaginating the movement restriction device in the pouch, comprising enclosing the device in the pouch.
