A minimally invasive system and method for providing weight loss by inducing the feeling of satiety whereby reconditioning experiences are combined with an intragastric device that is inserted into the gastric lumen via the esophagus and an external magnetic device is used as needed to magnetically attract the intragastric device towards the inner wall of the stomach.

A device for treating obesity of a patient, the device comprising: at least one operable stretching device implantable in the patient and adapted to stretch a portion of the patient's stomach wall, and an implantable control unit for automatically controlling the operable stretching device, when the control unit and stretching device are implanted, to stretch the stomach wall portion in connection with the patient eating such that satiety is created.

An assembly including a bougie and a sheath for use in performing a gastroplasty for dividing a stomach of a patient into a sleeve receiving food and a bypass portion. The bougie includes an elongated body having a segment being shaped to follow a lesser curve of the stomach, and an extension member being movable within the stomach for positioning a distal portion thereof away from a gastroesophageal junction of the stomach and to define a fluid passage between the sleeve and the bypass portion. The sheath has an elongated main lumen in which the bougie is inserted and the sheath is translatable along the bougie to selectively expose the extension member of the bougie to perform its guiding action, or hide the extension member to ensure secure displacement of the bougie within the stomach and along the oesophagus.

The present invention relates to a reflux disease treatment apparatus, comprising two or more movement restriction device segments adapted to form an implantable movement restriction device with an elongated shape that maintains cardia in the correct position. The movement restriction device has proximal and a distal end, wherein the distal end is adapted to stabilize and hold the proximal 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 intraluminar method of treating obesity of a patient, having a stomach with a food cavity, is disclosed. The method comprises the steps of creating a pouch made of a stomach wall portion of the patient, closing the pouch by sutures, staples or a fixation device, and placing a volume filling device in the pouch before or after closing the pouch, and thus investigating the volume filling device in the pouch such that an outer surface of the volume filling device rests against an outer surface of the stomach wall.

A bariatric device and method of causing at least partial satiety in a recipient includes positioning a body in a recipient, the body having a wall defining a lumen, the wall configured to generally conform to the shape and size of the proximal cardiac portion of the stomach. Force is exerted with the wall on the proximal cardiac portion of the stomach in the absence of food thereby activating receptors located in the proximal cardiac portion of the stomach, thereby influencing a neurohormonal feedback mechanism of the recipient to cause at least partial satiety by augmenting fullness caused by food and simulating fullness in the absence of food.

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 reduced in size.

A system for bypassing a portion of a small intestine. The system includes an occlusion device and a bypass device. The occlusion device includes a tubular body, an occlusion member at a distal end portion of the tubular body, and an anchor member at a proximal end portion of the tubular body. The bypass device includes a liner, and an anchor member at a proximal end portion of the liner.

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 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.
