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:

an implantable operable stretching device configured for actively stretching a portion of the patient'"'"'s stomach wall for actively creating a sensation of satiety,

an implantable control unit for automatically controlling the active stretching of the stomach wall by controlling the implantable operable stretching device,

a conduit or electrical lead connected to the implantable operable stretching device and to the implantable control unit for transferring at least one of force, electrical energy and control signals from the implantable control unit to the implantable operable stretching device, wherein

the implantable control unit further comprises a wireless signal receiving unit adapted to receive wireless command signals for altering the control of the implantable operable stretching device.

2. The device according to claim 1, further comprising a force sensor connected to the implantable control unit, the force sensor being configured for sensing force used for stretching the stomach wall portion.

3. The device according to claim 1, wherein the implantable operable stretching device is configured for being invaginated in the stomach wall.

4. The device according to claim 1, wherein the implantable operable stretching device comprises a first stomach engaging member configured to engage a first portion of the stomach wall, and a second stomach engaging member configured to engage a second portion of the stomach wall, and an operation device connected to the first and second stomach engaging member and configured for moving the first and second stomach engaging members away from each other for stretching the stomach wall between the first and second stomach engaging members.

5. The device according to claim 3, wherein the implantable operable stretching device comprises an expandable body configured to expand when invaginated in the stomach wall, to thereby stretch the stomach wall.

6. The device according to claim 1, further comprising a second implantable operable stretching device connected to the implantable control unit by a second conduit or electrical lead.

7. The device according to claim 1, further comprising a food intake sensor connected to the implantable control unit, the food intake sensor being configured for sensing food intake of the patient, and wherein the implantable control unit is further configured for controlling the active stretching of the stomach wall on the basis of the food intake of the patient.

8. The device according to claim 5, wherein the expandable body is connected to the conduit, and wherein the device further comprises a hydraulic reservoir connected to the conduit and a hydraulic operation device configured to transfer hydraulic fluid from the hydraulic reservoir to the expandable body for operating the stretching device.

9. The device according to claim 5, wherein the expandable body comprises an electrical motor configured for actively expanding the volume of the expandable body, wherein the electrical motor is connected to the electrical lead, and wherein implantable control unit is configured to control the electrical motor to thereby control the expansion of the expandable body.

10. The device according to claim 4, wherein the operation device is at least one of a mechanical operation device and a hydraulic operation device.

11. The device according to claim 1, further comprising a second implantable operable stretching device configured for actively stretching a second portion of the patient'"'"'s stomach wall for actively creating a sensation of satiety, and wherein the implantable control unit is adapted to control the implantable operable stretching device and the second implantable operable stretching to stretch a first and second portion of the stomach wall.

12. The device according to claim 11, wherein the implantable control unit is adapted to control the implantable operable stretching device, during a first time period, to stretch a first portion of the stomach wall, and control the second implantable operable stretching device, during a second time period, to stretch a second portion of the stomach wall, to allow longer relaxation of the stomach wall in between stretching periods.

13. The device according to claim 1, wherein the device further comprises an energy source to power the device comprising at least one of:

a wireless energy receiver for non-invasively energizing the device with wireless energy,

an internal energy source, and

an internal energy source adapted to receive energy from an external energy source in a wireless mode.

14. The device according to claim 7, wherein the food intake sensor is adapted to sense at least one of:

contraction and relaxation of the Cardia or esophagus, 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, capacitance, resistance, volt, ampere, light absorption or visualization, ultrasound reflection or absorption, bending metal, bimetal and PH.

15. The device according to claim 1, wherein the device further comprises an external data communicator and an implantable internal data communicator communicating with the external data communicator, wherein the internal communicator is adapted to feed data related to the device for treating obesity or the patient back to the external data communicator or the external data communicator feeds data to the internal data communicator.

16. The device according to claim 1, wherein the stretching device is provided with a coating, wherein the coating is at least one of:

a Parylene coating, a polytetrafluoroethylene coating, a polyurethane coating, a metal coating or a combination of the coating in a multi-layer coating construction.

17. The device according to claim 5, wherein the expandable body comprises a bellows adapted to take into account the fibrosis surrounding the device when implanted, such that the movement of the bellows is substantially un-affected by said fibrosis.

18. The device according to claim 2, wherein the force sensor is configured to sense one of pressure, a stomach pressure, a esophagus pressure, movement, stretching and stomach stretching.
