Methods and instruments for treating GERD and hiatal hernia

1.

introducing a gastroscope in the patient's oesophagus and into the patient's stomach;

introducing an instrument in the oesophagus and into the stomach of the patient, the instrument being integrated in the gastroscope or being separate from the gastroscope;

providing, by means of the instrument, a pouch from the patient's stomach fundus wall for accommodating the device;

invaginating the device in the pouch with sutures or staples to the stomach fundus wall, to thereby prevent the cardia from sliding through the patient's diaphragm opening into the patient's thorax, so as to maintain the supporting pressure against the patient's cardia sphincter muscle exerted from the patient's abdomen;

creating, by means of the instrument a pouch of a portion of the stomach fundus wall;

introducing the device into the pouch;

invaginating the device with sutures or staples to the stomach fundus wall; and

injecting a filling fluid into the device so it obtains its filling volume.
