Abstract

In some embodiments, methods to sense parameters associated with restriction procedures and/or devices are disclosed. In some embodiments, the parameters are sensed directly from the region of the procedure and/or device and in other embodiments, associated neural pathways are sensed. Methods for further optimization of the obesity treatment regimens are also disclosed.

Claims

1. A system to treat an obese patient comprising:

a) an adjustable implantable band having a volume of fluid therein and adapted to encircle the stomach;

b) an implantable pressure sensor adapted to measure changes in fluid pressure within the band, the fluid pressure changes related to patient ingestion of food which passes through the lumen of the stomach of the patient;

c) a controller adapted to change the volume of the fluid in the band in response to the changes in fluid pressure within the band; and

d) a gain control associated with the controller, wherein the gain control is adapted to increase or decrease the magnitude of the change in volume.

2. The system of claim 1 further comprising an automated system which fills or empties the band based on measurements from the pressure sensor.

3. The system of claim 1 further comprising a subcutaneous access port and wherein said pressure sensor is located within said port.

4. The system of claim 3 wherein said subcutaneous access port is configured to allow for calibration of the pressure sensor or charging of a power supply.

5. The system of claim 1 further comprising telemetry hardware which enables communication through the skin of a patient.

6. The system of claim 1 further comprising an inductive circuit configured to receive power through the skin of the patient.

7. The system of claim 1 further comprising an electrical stimulator adapted to provide stimulation to the gastrointestinal system of a patient.

8. The system of claim 7 wherein said electrical stimulator is activated when a food bolus passes through the lumen of the stomach.

9. A system to treat an obese patient comprising:

a) an adjustable implantable band having a volume of fluid therein and adapted to encircle the stomach;

b) an implantable sensor for generating an input signal in response to a physiological change in the patient, the implantable sensor selected from the group consisting of a strain gauge sensor, a circumferential tension sensor, a volume sensor;

a temperature sensor, a peristaltic wave sensor, and a pH sensor;

c) a controller adapted to change the volume of the fluid in the band in response to the changes in fluid pressure within the band; and

d) a gain control associated with the controller, wherein the gain control is adapted to increase or decrease the magnitude of the change in volume.

10. The system of claim 9, wherein the sensor is located on the band.

11. The system of claim 9, wherein the sensor is located on a structure attached to the band.

12. The system of claim 11, wherein the structure attached to the band is a balloon.

13. The system of claim 12, wherein the balloon comprises electrically activated material.

14. The system of claim 13, wherein the electrically activated material is a magnetorheologic fluid.

15. The system of claim 11, wherein the balloon comprises a shape memory alloy.

16. The system of claim 15, wherein the shape memory alloy comprises nickel-titanium alloy.

17. The system of claim 9, wherein the sensor is located on the stomach.

18. The system of claim 9, wherein the sensor is a circumferential tension sensor adapted to measure tension within the band, the tension related to passage of food through the digestive system.

19. The system of claim 9, wherein the sensor is a volume sensor adapted to measure volume changes in the digestive system.

20. The system of claim 19, wherein the volume changes in the digestive system are in the stomach.

21. The system of claim 19, wherein the volume changes in the digestive system are in the distal esophagus.

22. The system of claim 9, wherein the sensor is a peristaltic wave sensor adapted to measure contraction of a digestive system structure.

23. The system of claim 22, wherein the digestive system structure is the stomach or esophagus.
