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.

An orthopedic joint device having a lower leg part, a foot part that is arranged on the lower leg part about a swivel axis such that it can be swivelled, at least a first energy store, and a coupling element. The coupling element can be brought into a coupling position, in which a swivelling of the foot part relative to the lower leg part about the swivel axis in a plantar flexion direction leads to an increase in the amount of energy stored in the first energy store, and a de-coupling position. The orthopedic joint device also has at least one release element, which can be brought into a release position and a locked position. The energy stored in the first energy store can be released by bringing the release element into the release position.

The present invention relates to a reflux disease treatment apparatus, comprising an implantable movement restriction device with an elongated shape that maintains cardia in the correct position and an implantable stimulation device adapted to engage with the cardia sphincter of a patient. The movement restriction device has a proximal and a distal end, wherein the distal end is adapted to stabilize and hold the distal end. The invention further comprises a control device for controlling the stimulation device to stimulate the cardia sphincter. The distal end can be further adapted to treat obesity, for example by stretching the wall of the stomach or filling out a volume of the stomach.

An apparatus for the treatment of acid reflux disease has an implantable movement restriction device adapted to be at least partly 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. The movement restriction device has a size of at least 125 mm.sup.3 and a circumference of at least 15 mm.

An apparatus for treating obesity and reflux disease of an obese patient has a volume filling device to be invaginated by a stomach wall portion 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. An implantable movement restriction device to be invaginated by the stomach fundus wall has an outer surface to be rested against the stomach wall in a position between the patient's diaphragm and 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.

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.

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.
