Abstract

An apparatus for treating obesity and reflux disease of an obese patient has a volume filling device to be invaginated by a stomach wall portion with the outer surface of the volume filling device resting against the stomach wall, such that the volume of the food cavity is reduced in size by a volume substantially exceeding the volume of the volume filling device. An implantable movement restriction device to be invaginated by the stomach fundus wall has an outer surface to be rested against the stomach wall in a position between the patient'"'"'s diaphragm and the lower part of the invaginated stomach fundus wall, such that movement of the cardiac notch of the patient'"'"'s stomach towards the patient'"'"'s diaphragm is restricted, to thereby prevent the cardia from sliding through the patient'"'"'s diaphragm opening into the patient'"'"'s thorax.

Claims

1. An apparatus for treating obesity and reflux disease of an obese patient having a stomach with a food cavity, the apparatus comprising:

—

at least one volume filling device adapted to be at least substantially invaginated by a stomach wall portion of the patient and having an outer surface that includes a biocompatible material, wherein the volume filling device is adapted to be placed with the outer surface of the volume filling device resting against the stomach wall, such that the volume of the food cavity is reduced in size by a volume substantially exceeding the volume of the volume filling device, the volume filling device having a maximum circumference of at least 30 millimeters, and an implantable movement restriction device adapted to be at least partly invaginated by the patient'"'"'s stomach fundus wall and having an outer surface that includes a biocompatible material, wherein a substantial part of the outer surface of the movement restriction device is adapted to rest against the stomach wall without injuring the latter in a position between the patient'"'"'s diaphragm and at least a portion of the lower part of the invaginated stomach fundus wall, such that movement of the cardiac notch of the patient'"'"'s stomach towards the patient'"'"'s diaphragm is restricted, when the movement restriction device is invaginated, to thereby prevent the cardia from sliding through the patient'"'"'s diaphragm opening into the patient'"'"'s thorax, so as to maintain the supporting pressure against the patient'"'"'s cardia sphincter muscle exerted from the patient'"'"'s abdomen, the movement restriction device having a size of at least 125 mm³ and a circumference of at least 15 mm.

2. The apparatus according to claim 1, further comprising an implantable first fixation device that, when implanted in the patient, secures the movement restriction device in a position that restricts the movement of the cardiac notch of the stomach towards the patient'"'"'s diaphragm, with the outer surface of the movement restriction device substantially contacting the patient'"'"'s stomach fundus wall.

3. The apparatus according to claim 1, wherein the movement restriction device is non-adjustable from outside the patient'"'"'s body when implanted in the patient.

4. The apparatus according to claim 2, wherein the first fixation device comprises a tissue growth promoting structure for long term attachment of the movement restriction device to the stomach wall without invagination.

5. The apparatus according to claim 4, wherein the tissue growth promoting structure comprises a net like structure.

6. The apparatus according to claim 5, wherein the tissue growth promoting structure further comprises sutures or staples that, when implanted in the patient, attach the net like structure to the fundus stomach wall.

7. The apparatus according to claim 2, wherein the first fixation device comprises sutures or staples that, when implanted in the patient, attach together portions of the fundus stomach wall that enclose the movement restriction device to secure the movement restriction device in said position.

8. The apparatus according to claim 7, wherein the sutures or staplers, when implanted in the patient to attach together portions of the fundus stomach wall, invaginate the movement restriction device in the fundus stomach wall to thereby keep the movement restriction device in place.

9. The apparatus according to claim 8, wherein the sutures or staplers, when implanted in a patient with the movement restriction device, attach together portions of the fundus stomach wall so at to invaginate the movement restriction device from inside of the patient'"'"'s stomach wall.

10. The apparatus according to claim 8, wherein the sutures or staplers, when implanted in a patient with the movement restriction device, attach together portions of the fundus stomach wall so at to invaginate the filing movement restriction device from outside of the patient'"'"'s stomach wall.

11. The apparatus according to claim 2, further comprising a second fixation device that, when implanted in the patient with the movement restriction device, secures, indirectly or directly, the movement restriction device to the oesophagus close to the patient'"'"'s angle of His.

12. The apparatus according to claim 11, wherein the second fixation device is comprised of a plurality of sutures or staples that, when implanted in the patient with the movement restriction device, attach the fundus wall and a wall of the patient'"'"'s oesophagus to hold the movement restriction device in said position.

13. The apparatus according to claim 11, further comprising a third fixation device that, when implanted in the patient with the movement restriction device, secures, indirectly or directly, the movement restriction device to the patient'"'"'s diaphragm muscle or associated muscles.

14. The apparatus according to claim 13, wherein the third fixation device is comprised of a plurality of sutures or staples that, when implanted in the patient with the movement restriction device, attach the fundus wall and the diaphragm muscle or associated muscles to hold the movement restriction device in said position.

15. The apparatus according to claim 1, wherein the movement restriction device comprises a body adapted to be at least partly invaginated by the patient'"'"'s stomach fundus wall and having an outer surface that includes a biocompatible material, a substantial part of the outer surface of the body being adapted to rest against the stomach wall in said position between the patient'"'"'s diaphragm and the portion of the lower part of the invaginated stomach fundus wall.

16. The apparatus according to claim 15, wherein the body is substantially egg shaped.

17. The apparatus according to claim 15, wherein the body is substantially shaped like an egg with an indented middle section.

18. The apparatus according to claim 15, wherein the body is substantially shaped like a bent egg.

19. The apparatus according to claim 15, wherein the body is substantially spherically shaped.

20. The apparatus according to claim 15, wherein the body has rounded contours without too sharp edges that would be damaging to the patient'"'"'s stomach wall.
