Abstract
A food intake restriction device for forming a restriction in a patient's gastro-intestinal tract and non-invasively communicating pressure data regarding the restriction to an external monitor. The device includes a food intake restriction device implanted substantially about a patient's gastro-intestinal tract to form a restricted opening in the tract. A port is connected to the restriction device. The port contains a working fluid for affecting the size of the restricted opening.
