    摘要: Methods and devices for optimizing the operation of a restriction system for forming a restriction in a patient are disclosed. In one exemplary embodiment, a method for optimizing the operation of a gastric restriction system includes providing an implantable restriction system for forming a restriction in a patient, determining an optimum value of a control parameter of the restriction system, and maintaining the control parameter at the optimum value such that a result parameter of the restriction system is substantially convergent as a function of time. Determining an optimum value of a control parameter can generally include adjusting the restriction device, determining the value of the control parameter to be optimized, and repeating the steps of adjusting the restriction device and determining the value of the control parameter until the control parameter is substantially convergent as a function of time.

    摘要: 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.
