CLAIMS

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. An intraluminal device, comprising:

a body having a wall defining a surface, said surface configured to a portion of a lumen; and

an anchor system, said anchor system configured to fix said body to an inner wall of the lumen in a manner that said surface is adapted to apply at least intermittent pressure to the inner wall of the lumen; and

a tissue fold that is adjacent the wall said tissue fold transmitting a force between the inner wall of the lumen and said body.

2. The device as claimed in claim 1 wherein said anchor system comprises a plurality of anchors, each comprising a fastener that is adapted to retain said wall with the tissue fold of the lumen that is adjacent the wall.

3. The device as claimed in claim 2 wherein each of said anchors comprises at least one opening in said wall and a crossbar at an edge portion of said at least one opening, the tissue fold positioned in said at least one opening,

4. The device as claimed in claim 2 wherein said at least one opening is at an edge portion of said body.

5. The device as claimed in claim 2 wherein each of said anchors comprises an opening traversed by a crossbar, with a tissue fold of the lumen extending into the opening on opposite sides of the crossbar and said fastener adapted to couple the tissue folds in a manner that retains the crossbar between the tissue folds.

6. The device as claimed in claim 5 wherein said wall has a central opening and a

peripheral edge and wherein said anchors are spaced from both said central opening and said peripheral edge.

7. The device as claimed in any of the preceding claims wherein said anchor is adapted to be disabled in order to explant the body from the lumen.

8. The device as claimed in claim 7 wherein said anchor is adapted to be disabled by

cutting the fastener.

9. The device as claimed in claim 7 wherein said anchor is adapted to be disabled by said crossbar being adapted to be removed from adjacent said opening.

10. The device as claimed in claim 9 wherein a plurality of said crossbars are adapted to be removed together by being interconnected in a crossbar assembly.

11. The device as claimed in claim 10 wherein said crossbars are adapted to be removed together by being attached at one end with a removable attachment with said wall and having a grasping portion at an opposite end.

12. The device as claimed in claim 1 wherein said surface is adapted to apply an adjustable pressure to the inner wall of the lumen.

13. The device as claimed in claim 12 wherein the surface is moveable with an inner

bladder and a control system adjusting inflation of said inner bladder.

14. The device as claimed in claim 13 wherein said control system includes a controller and an outer bladder on an opposite side of said wall, said controller exchanging a fluid between said bladders in order to move said surface.

15. The device as claimed in claim 12 wherein said anchor system includes another body that is connected with said body and wherein the tissue fold connected with a controller on said wall with a filament.

16. The device as claimed in claim 15 wherein said body is configured to the cardiac

portion of the stomach and said anchor system comprises said another body adapted to be fixed to a distal portion of the esophagus.

17. The device as claimed in claim 15 or claim 16 wherein said control system includes a controller on said wall that is connected with the tissue fold with a filament to transmit a force between said tissue fold and said wall, said controller adapted to adjust a length of said filament to adjust a force between said body and said tissue fold to adjust pressure applied by the surface to the inner wall of the lumen.

18. A method of deploying an intraluminal device in a portion of a lumen, said method comprising:

said device having a body with a wall defining a surface, said surface configured to a portion of a lumen;

an anchor system;

fixing said body to an inner wall of the lumen with said anchor system and applying at least intermittent pressure with said surface to the inner wall of the lumen; and

forming a tissue fold of the inner wall of the lumen, the tissue fold being adjacent the body wall, said tissue fold transmitting a force between the inner wall of the lumen and said body.

19. The method as claimed in claim 18 wherein said anchor system comprises a plurality of anchors, said fixing including retaining said wall with the tissue fold of the lumen.

20. The method as claimed in claim 19 wherein each of said anchors comprises at least one opening in said wall and a crossbar at an edge portion of said at least one opening, including forming the tissue fold in said at least one opening,

21. The method as claimed in claim 19 wherein said at least one opening is at an edge

portion of said body.

22. The method as claimed in claim 19 wherein each of said anchors comprises an opening traversed by a crossbar, including forming at least two tissue folds of the lumen each extending into said opening on opposite sides of said crossbar and coupling the tissue folds with a fastener in a manner that retains the crossbar between the tissue folds.

23. The method as claimed in claim 19 wherein said wall has a central opening and a

peripheral edge and wherein said anchors are spaced from both said central opening and said peripheral edge.

24. The method as claimed in any of claims 19 through 23 including disabling said anchors in order to explant the body from the lumen.

25. The method as claimed in claim 24 including disabling said anchor by cutting the

fastener.

26. The method as claimed in claim 24 including disabling said anchor by removing said crossbar from adjacent said at least one opening.

27. The method as claimed in claim 26 wherein a plurality of said crossbars are

interconnected and including removing said plurality of crossbars together.

28. The method as claimed in claim 27 wherein said pluralities of crossbars are

interconnected by being attached at one end with a removable attachment with said wall and having a grasping portion at an opposite end.

29. The method as claimed in any of claim 18 including applying an adjustable pressure with said surface to the inner wall of the lumen.

30. The method as claimed in claim 29 wherein applying an adjustable pressure includes the surface being moveable with an inner bladder and a control system adjusting inflation of said inner bladder.

31. The method as claimed in claim 30 wherein said control system includes a controller and an outer bladder on an opposite side of said wall, said controller exchanging a fluid between said bladders in order to move said surface.

32. The method as claimed in any of claim 18 wherein said wall is shaped to the cardiac portion of the stomach and having a central opening.

33. The method as claimed in claim 32 including deploying said wall with a deployment device and aligning said central opening with the esophageal gastric junction using said deployment device.

34. The method as claimed in claim 32 including retention filaments extending from said wall to external the recipient of the device and retaining said wall to the cardiac portion of the stomach of the recipient during said deployment.

35. The method as claimed in claim 19 wherein said anchor system includes another body that is connected with said body and wherein the tissue fold connected with a controller on said wall with a filament.

36. The method as claimed in claim 35 wherein said body is configured to the cardiac

portion of the stomach and said anchor system comprises fixing said another body to a distal portion of the esophagus.

37. The method as claimed in claim 35 or claim 36 wherein said control system includes a controller on said wall that is connected with the tissue fold with a filament to transmit a force between said tissue fold and said wall, said controller adjusting a length of said filament thereby adjusting a force between said body and said tissue fold thereby adjusting pressure applied by the surface to the inner wall of the lumen.
