1. ) An implantable system to treat an obese patient comprising:
- a) an adjustable restriction device comprising a volume of fluid;
b) an implantable pressure sensor adapted to record a changes in fluid pressure within the restriction device, the fluid pressure changes related to patient ingestion of food which passes through the lumen of the stomach of the patient.

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.

16. ) The method of monitoring an adjustable restriction device in a patient comprising:
-
a) detecting pressure changes in the restriction device as a bolus of food passes through the stomach;
b) recording at least one of;
the degree of pressure change with time of the food bolus, consistency of the food bolus, frequency of meals, and meal volume.c) changing the volume within the adjustable rerstriction device based on the recording.
