Abstract

In an adaptive device and an adaptive method for adapting the stomach opening of a patient, a gastric band having a non-elastic back part on the exterior and a first expandable chamber on the interior are placed around the stomach of the patient for adapting the stomach opening, and the stomach opening of the patient is adapted by modifying the amount of fluid in the first expandable chamber. For this purpose, the adaptive device includes a second expandable chamber, so that the second expandable chamber is connected to the first expandable chamber, and whereby the fluid is displaced from the one expandable chamber to the other expandable chamber in order to modify the stomach opening of the patient. The adaptive device can in particular be controlled by changing the position of the body of the patient.

Claims

1-24. -24. (canceled)

25. An adaptive device for automated adaptation of the stomach opening of a patient, comprising a gastric band with a non-elastic back part and a first expandable chamber, and a second expandable chamber connected to the first expandable chamber, the gastric band being placeable around the stomach of the patient for adaptation of the stomach opening of the patient, and the fluid being displaceable from the one expandable chamber into the other expandable chamber by a conveyance device, a switching device with a sensor module being provided for activation of the conveyance device, a measurement value being able to be registered by the sensor module, and the switching device being controllable in an automated way based on the change in the measurement value, wherein the change in the position of the body of the patient or the change in the pressure on the inner wall of the esophagus of the patient is able to be registered by the sensor module.

26. The adaptive device according to claim 25, wherein the conveyance device is driven mechanically and/or electrically.

27. The adaptive device according to claim 25, wherein the conveyance device is designed as a hydraulic pump.

28. The adaptive device according to claim 25, wherein the adaptive device comprises a power storage device for driving the conveyance device, the conveyance device being electrically connected to the power storage device.

29. The adaptive device according to claim 28, wherein the power storage device is rechargeable.

30. The adaptive device according to claim 25, wherein the adaptive device comprises a line for connection of the first expandable chamber to the second expandable chamber.

31. The adaptive device according to claim 30, wherein the line comprises a valve, the valve being controllable by the switching device.

32. The adaptive device according to claim 25, wherein a delay module is provided by which the activation of the switching device is controllable.

33. The adaptive device according to claim 32, wherein the delay module is programmable.

34. The adaptive device according to claim 32, wherein the delay module is programmable and/or controllable by a remote control.

35. The adaptive device according to claim 25, wherein the adaptive device is made substantially of synthetic material.

36. An adaptive method for automated adaptation of the stomach opening of a patient, a gastric band with a non-elastic back part and a first expandable chamber being placeable around the stomach of the patient for adaptation of the stomach opening of the patient, and the fluid being displaceable from the one expandable chamber into the other expandable chamber by a conveyance device, for activation of the conveyance device, a measurement value being registered by a sensor module, and a switching device being controlled in an automated way, based on the change in the measurement value, wherein the change in the position of the body of the patient or the change in the pressure on the inner wall of the esophagus of the patient is registered by the sensor module.

37. The adaptive method according to claim 36, wherein the conveyance device is driven mechanically and/or electrically.

38. The adaptive method according to claim 36, wherein the conveyance device is designed as a hydraulic pump.

39. The adaptive method according to claim 36, wherein the conveyance device is electrically connected to a power storage device.

40. The adaptive method according to claim 36, wherein the first expandable chamber is connected to the second expandable chamber by a line.

41. The adaptive method according to claim 40, wherein a valve of the line is controlled through the switching device.

42. The adaptive method according to claim 36, wherein the activation of the switching device is controlled by a delay module.

43. The adaptive method according to claim 42 wherein the delay module is programmed.

44. The adaptive method according to claim 42, wherein the delay module is programmed and/or controlled by a remote control.
