Abstract

A device for treating obesity of a patient, the device comprising: at least one operable stretching device implantable in the patient and adapted to stretch a portion of the patient'"'"'s stomach wall, and an implantable control unit for automatically controlling the operable stretching device, when the control unit and stretching device are implanted, to stretch the stomach wall portion in connection with the patient eating such that satiety is created.

Claims

1. A device for treating obesity of a patient, the device comprising:

a. at least one operable stretching device implantable in the patient and adapted to stretch a portion of the patient'"'"'s stomach wall, and

b. an implantable control unit for automatically controlling the operable stretching device, when the control unit and stretching device are implanted, to stretch the stomach wall portion in connection with the patient eating such that satiety is created.

2. The device according to claim 1, further comprising at least two stretching devices, a first stretching device and a second stretching device.

3. The device according to claim 2, further comprising three or more stretching devices.

4. The device according to claim 1, further comprising an operation device for operating the stretching device, wherein the control unit controls the operation device to stretch the stomach wall portion, when the control unit and stretching device are implanted.

5. The device according to claim 1, further comprising a sensing device including a sensor for sensing a physical parameter of the patient or a functional parameter of the stretching device, wherein the sensing device sends information relating to the parameter to the control unit, and the control unit controls the stretching device based on the information.

6. The device according to claim 1, wherein the implantable control unit is adapted to control the stretching device to intermittently stretch the stomach wall, when the control unit and stretching device are implanted.

7. The device according to claim 1, wherein the implantable control unit is adapted to control the amount of stretching performed by the stretching device on the stomach wall.

8. The device according to anyone of claim 7, wherein the control unit controls the stretching device to vary over time the amount of stretching of the stomach wall.

9. The device according to claim 1, wherein the implantable control unit is adapted to control the stretching device to stretch the stomach wall during a predetermined time period.

10. The device according to claim 1, wherein the implantable control unit is adapted to control the stretching device based on the patient'"'"'s food intake.

11. The device according to claim 1, wherein the implantable control unit is programmable to include any of:

a) predetermined time period during which the stretching device is controlled 20 to stretch the stomach wall, and

b) the magnitude of stretching applied on the stomach wall.

12. The device according to claim 4, wherein the operation device is a mechanical operation device.

13. The device according to claim 4, wherein the operation device is a hydraulic operation device.

14. The device according to claim 4, wherein the operation device is a hydraulically operated mechanical operation device.

15. The device according to claim 4, wherein the operation device is a mechanically operated hydraulic operation device.

16. The device according to claim 5, wherein the sensor of the sensing device senses the patient'"'"'s food intake directly or indirectly, and the implantable control unit controls the operation device to stretch the stomach wall in response to signals from the sensor.

17. The device according to claim 2, wherein the implantable control unit is adapted to control the operation device to stretch the stomach wall using more than one stretching device.

18. The device according to claim 2, wherein the implantable control unit is adapted to control;

a) the first stretching device, during a first time period, to stretch a first portion of the stomach wall, and b) the second stretching device, during a second time period, to stretch a second portion of the stomach wall different from said first portion of the stomach, to allow longer relaxation of the stomach wall in between stretching periods.

19. The device according to claim 16, wherein the sensor of the sensing device is adapted to sense a parameter related to the patients food intake.

20. The device according to claim 19, wherein the parameter is one of esophagus movement, esophagus bending, esophagus motility, esophagus stretching, esophagus pressure, food passing esophagus, food in the stomach, neural activity, vagus activity, muscle activity, hormonal activity, stomach motility, stomach stretching, stomach pressure, stomach bending, stomach filling, and acidity in the stomach.
