An implantable apparatus for treating reflux disease in a human or animal mammal patient, the implantable apparatus being configured to be fixated to the stomach of the patient and comprising two or more implantable movement restriction device segments, wherein each implantable movement restriction device segment is provided with at least one assembly element that fits with at least one assembly element of another of said two or more implantable movement restriction device segment, so the two or more implantable movement restriction device segments by said assembly elements can be assembled into an implantable assembled movement restriction device.

An implantable medical device for treating reflux disease in a human patient, the implantable medical device comprising a movement restriction device having an outer surface including a biocompatible material. The movement restriction device is adapted to be fully invaginated by the stomach fundus wall of the patient, such that movement of the cardiac notch of the patient's stomach towards the patient's diaphragm is restricted, thereby preventing the cardia from sliding through the patient's diaphragm opening into the patient's thorax. The implantable medical device further comprises a holding device adapted to be held by a surgical instrument, wherein the holding device is at least partly placed inside the outer wall of the implantable medical device.

An apparatus for treating obesity comprises a volume filling device formed by at least two segments and is provided and following implantation, the device is placed resting against the stomach wall of the patient to reduce the inner volume of the stomach, thereby affecting the patient's appetite.

A method of affecting the appetite of a human person using a device adapted to be non-invasively operated for actively stretching a portion of the stomach wall of the person. The device comprising a first portion adapted to be fixated to a first area of the stomach wall of the person, a second portion adapted to be fixated to a second area of the stomach wall of the person, and an operation device. The method comprising the step of the operation device actively and non-invasively operating at least one of the first and second portions to move the first and second portions away from each other to thereby actively stretch the stomach wall between the first and second area of the stomach, such that a feeling of satiety is created.

An apparatus for treating obesity in a human or animal mammal patient. The apparatus comprising a first volume filling device segment and a second volume filling device segment. The first and second volume filling device segments are adapted to be assembled into an implantable volume filling device of a controlled size. Each one of the first and second volume filling device segment comprises at least one interconnecting structure. The interconnecting structure of the second volume filling device segment is adapted to be formed fitted, such that the first and second volume filling device segment can be assembled into the volume filling device. The assembled volume filling device is adapted to be at least substantially invaginated by a stomach wall portion of a patient, with the outer surface of the device resting against the stomach wall, such that the volume of the food cavity is recuced in size.

The invention relates to an intraluminar method of treating a reflux disease in a patient by implanting a device comprising an movement restriction device that, when implanted in a patient, fills a volume in the patient's abdomen that is close to and at least partially above the patient's cardia when the patient is in a standing position. The invention further relates to a method of restoring the location of the cardia in a patient suffering from a reflux disease and to an instrument suitable to use with intraluminar method and/or restoration method. Also disclosed are instruments treating a patient suffering hiatal hernia and providing a movement restriction device to be invaginated in the stomach fundus wall.

A 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 obesity treatment apparatus comprises 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.

A reflux disease treatment apparatus comprising an implantable movement restriction device that maintains cardia in the correct position and an implantable stimulation device adapted to engage with the cardia sphincter of a patient. The invention further comprises a control device for controlling the simulation device to stimulate the cardia sphincter. The invention can be combined with various methods for treating obesity, in particular methods that creates satiety by stretching the wall of the stomach or fills out a volume of the stomach.

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.
