The device, when implanted in a patient, fills a volume in the patient's abdomen in the cardia area and above the cardia of the patient, when standing. The body prevents the cardia from moving through the diaphragm opening into the thorax (20), thereby preventing reflux by keeping the abdominal pressure supporting the cardia sphincter muscle. The device may be affixed to stomach tissue. The device may also be invaginated or otherwise indirectly secured in position.
