Abstract: The disclosure relates to a surgically implantable apparatus for providing selective fluid communication with the interior of the body of a patient. In a preferred embodiment, the apparatus includes an annular body permanently implanted in the abdominal wall and provides fluid communication to an internal tube placed in the gastrointestinal tract to facilitate feeding of a patient whose normal digestion process is inadequate. The internal tube is replaceable without surgery or removal of the annular body. The annular body houses a spring biased valve which is opened by coupling the annular body to an external conduit for nutrient fluid. The annular body includes flanges and tissue fixation material which permit regrowth of the abdominal wall tissue about the annular body.
