Abstract

A gastroscopic method of treating obesity of a patient using a device adapted to stretch a part of the stomach wall of said patient. The method comprising the steps of: inserting said device into the stomach of said patient through the esophagus, placing said device in contact with the stomach wall and fixating said device to the stomach wall such that said device can stretch a part of said stomach wall.

Claims

1. An instrument for placing an inflatable device, adapted to stretch a part of the stomach wall of a patient, in connection with said stomach wall, said instrument comprising:

a stomach holding device adapted to be brought in engagement with at leat two separate portions of the stomach wall,

a stomach shaping device adapted to move a part of the stomach wall arranged between said at least two separate portions so as to create a recess in the stomach wall,

an insertion member adapted to insert the inflatable device in a non-inflated state into the stomach and place the inflatable device in the recess, and

a fixating member adapted to assist in the fixation of said inflatable device to the stomach wall,

wherein each of the stomach holding device, the stomach shaping device, the insertion member and the fixating member has a shape and size that allows it to be inserted into the stomach via an esophagus of the patient.

2. The instrument according to claim 1, wherein said instrument further comprises an optical member for viewing in the area of the stomach.

3. The instrument according to claim 1, wherein said fixating member is adapted to suturing or stapling said inflatable device to the stomach wall.

4. The instrument according to claim 1, wherein said fixating member is adapted for invaginating at least a part of said inflatable device in the stomach wall with stomach-to-stomach sutures.

5. The instrument according to claim 1, wherein said fixating member is adapted for invaginating at least a part of said inflatable device in the stomach wall with stomach-to-stomach staplers.

6. The instrument according to claim 1, wherein said insertion member is a cutting member for cutting a hole in the stomach wall, the cutting member having a shape and size allowing it to be inserted into the stomach via the esophagus.

7. The instrument according to claim 6, wherein said insertion member is adapted to insert the inflatable device in a non-inflated state through the hole in the stomach wall.

8. The instrument according to claim 6, wherein said fixating member is adapted to assist in the fixation of the inflatable device on the inside of the stomach wall.

9. The instrument according to claim 6, wherein said fixating member is adapted for invaginating at least a part of said inflatable device in the stomach wall with stomach-to-stomach sutures, on the inside thereof.

10. The instrument according to claim 6, wherein said fixating member is adapted for invaginating at least a part of said inflatable device in the stomach wall with stomach-to-stomach staplers, on the inside thereof.

11. The instrument according to claim 1, wherein the stomach shaping device comprises a vacuum sucking device adapted to suck the stomach wall to form the recess in the stomach wall.

12. The instrument according to claim 11, wherein the vacuum sucking device comprises a plurality of openings adapted to suck the stomach wall towards the stomach shaping device.

13. The instrument according to claim 11, comprising at least one clamping device for holding an opening of the recess substantially closed by clamping together portions of the stomach wall in said opening, wherein the instrument is adapted to place the at least one clamping device at the opening of the recess to allow subsequent suturing of the opening.

14. The instrument according to claim 11, wherein the instrument comprises an inflation device for inflating the inflatable device when it has been placed in the recess.

15. The instrument according to claim 11, wherein the fixating member is adapted to suture an opening of the recess with stomach to stomach sutures for creating at least partly a closed space enclosing the stretching device.

16. The instrument according to claim 15, wherein the fixating member comprises a first and a second suture positioning member provided on the elongated member at the distal end thereof, and

an operation device adapted to adjust the first and second suture positioning members in a position in which the first and second suture positioning members are in front of each other with the stomach wall on both sides of an edge of the recess, and adapted to suture an open end of the recess with a row of stomach to stomach sutures.

17. The instrument according to claim 15, wherein the fixating member comprises a reloading device adapted to reload the fixating member from outside the patient'"'"'s body.
