Abstract: Methods and apparatus for quantifying the amount or rate of magnetically susceptible fluid within a gastric lumen are described. In one aspect, a magnetic sensor located external to the patient is configured to detect a quantity of fluid disposed within the gastric lumen. The quantity of fluid may include fluid that is contained upstream with respect to a restriction formed in the gastric lumen (e.g., by a gastric restriction device). The quantity of fluid disposed within the gastric lumen is determined by the magnetic sensor. This quantity may be evaluated over time to then calculate a real time flow rate which can then be displayed to the physician. The methods and devices allow a physician or other trained person to dynamically view real time development of fluid flow within a restricted gastric lumen and may be used in conjunction with adjustments to the gastric restriction device to achieve target or desired flow rates.
