A gastroscopic method and instrument for treating obesity of a patient, using a device adapted to stretch a part of the stomach wall of said patient. The method comprises the steps of: inserting the device into the stomach through the esophagus, placing the device in contact with the stomach wall, and fixating the device to the stomach wall such that the device can stretch a part of the stomach wall.

An apparatus for treating obesity of a patient having a stomach with a food cavity. The apparatus comprising a volume filling device adapted to be at least substantially invaginated by a stomach wall portion of the patient with the outer surface of the volume filling device resting against the stomach wall, such that the volume of the food cavity is reduced in size by a volume substantially exceeding the volume of the volume filling device. The apparatus further comprises at least one adjustable stretching device adapted to be at least substantially invaginated by a stomach wall portion of the patient with the outer surface of the stretching device resting against the stomach wall and adapted to stretch a portion of stomach wall, and a fluid connection device interconnecting the volume filling device and the stretching device.

A post gastrectomy anchoring procedure comprises anchoring a sleeve created by a gastrectomy to tissue structure that can better immobilize the sleeve to reduce complications relating to mobility of the sleeve. Namely, the anchoring procedure secures one or more portions of the sleeve to retroperitoneal fat of a patient. One or more bindings attach the sleeve to the retroperitoneal fat.

The bindings can be installed to hold the sleeve in a bent or other shape, such as to mimic the natural shape of the patient's stomach and maintain an opening in the angularis of the sleeve.

An volume filling device for treatment of obesity is placed outside the stomach wall of the patient to reduce the inner volume of the stomach, thereby affecting the patient's appetite. By providing the volume filling device outside the stomach wall, contact with stomach acids is avoided, thereby increasing the life of the device.

An apparatus for the treatment of acid reflux disease comprising two or more movement restriction device segments adapted to be movement restriction device of a controlled size. The movement restriction device can at least partly be invaginated by a patient's stomach fundus wall. A substantial part of the outer surface of the movement restriction device is adapted to rest against the stomach wall without injuring the latter in a position between the patient's diaphragm and at least a portion of the lower part of the invaginated stomach fundus wall, such that movement of the cardiac notch of the patient's stomach towards the patient's diaphragm is restricted, 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.

A biocompatible implant for a method of treating a reflux disease in a patient by preventing the cardia sphincter from sliding through the patient's diaphragm hiatus opening into the patient's thorax, so as to maintain a pressure support from the patient's abdomen that supports the patient's cardia sphincter. The biocompatible implant has a rigid shape, a circumference of at least 15 mm and is configured to be introduced into the patent's abdomen through a trocar, be fully invaginatable in the patient's fundus wall, and function as an implantable movement restricting device preventing the cardia sphincter from sliding through the patient's diaphragm, when implanted.

An implantable device for the treatment of acid reflux disease has a body including an outer surface adapted to rest against a patient's fundus wall. The device, when implanted in the 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, 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.

An obesity treatment device is provided, the device comprising: at least one operable stretching device implantable in an obese patient and adapted to stretch a portion of the patient's stomach wall and an operation device for operating the stretching device when implanted to stretch the stomach wall portion such that satiety is created.
