1. An apparatus for controlling gastro-pharyngeal reflux in a patient, the apparatus comprising:

  • an enteral feeding tube having a double lumen, a gastric balloon, an esophageal balloon, a sensor for monitoring gastric pressure when enteral feeding is in process, and an external pump that regulates air or fluid pressure within said esophageal balloon, wherein the sensor monitors gastric pressure based upon a signal that is averaged using a filter algorithm, the filter algorithm configured to set that sets a gradient value that is added to actual gastric pressure, thereby defining a relative level of esophageal pressure, and wherein the pressure in the esophageal balloon is regulated by the external pump to the relative level of esophageal pressure and applied to seal from gastro-pharyngeal reflux.
