An implantable restriction device is configured to provide a restriction in a patient as a function of the pressure of fluid. The implantable restriction device includes one or more pressure sensors configured to sense pressure of the fluid within the implantable restriction device. Pressure data obtained by the one or more pressure sensors may be communicated to a device located external to the patient, which may process the pressure data, and may further provide a display to a user including information relating to the processed pressure data. Where the implantable restriction device comprises an adjustable gastric band, the one or more pressure sensors may be located in any number of the following locations: an injection port, an interface between the injection port and a catheter, in a catheter, in-line with a catheter, adjacent to a catheter, in a gastric band, in a gastric band buckle, or elsewhere.
