Abstract
A pressure sensor may be used to determine the pressure of fluid within an implantable gastric restriction device. An accelerometer may be used to measure movement of the patient in which the gastric restriction device is implanted, such that the movement may be accounted for when evaluating data from the pressure sensing system. For instance, movement data from the accelerometer may be used to identify pressure data that should be ignored. A display may annotate a pressure graph to show changes in pressure associated with patient movement; or may otherwise influence the display of pressure data based on patient movement. The pressure sensor and accelerometer may be incorporated into an adapter placed between a syringe and needle that are used to adjust the fluid pressure in the gastric restriction device. Upon examination of pressure data in relation to movement data, the implantable gastric restriction may be adjusted as needed.
