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 apparatus for treating obesity of an obese patient. The apparatus comprising a volume filling device adapted to be completely invaginated by a wall portion of a stomach of the patient. The volume filling device is adapted to be placed on the outside of the wall portion, with an outer surface of the volume filling device resting against the outside of the wall portion and such that a volume of a food cavity of the stomach is reduced in size by a volume having a treatment effect on the obesity.

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 intragastric device comprising: an inflation magnet provided within a capsule and configured to move towards a first end of a capsule during activation of the intragastric device by applying a magnetic field externally to a user after swallowing the intragastric device; a first chamber and a second chamber physically separated by a partition having a through hole; a separator connected to the inflation magnet and sealing the through hole before activation of the intragastric device, wherein activation of the intragastric device moves the separator to unseal the through hole to allow a chemical reaction between a first chemical stored in the first chamber and a second chemical stored in the second chamber; a balloon secured to the capsule and collapsed against the capsule before activation of the intragastric device; and an expandable volume configured to expand when the balloon is inflated by a gaseous product of the chemical reaction.

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

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.

In one aspect, a gastric balloon structure includes multiple isolated non-concentric inflatable chambers and a valve system for introducing fluid into each chamber, where the structure assumes, upon inflating, a curved shape conforming to a natural three-dimensional kidney shape of the gastric cavity.

In one aspect, an obesity treatment device includes multiple inflatable space-filling compartments and a valve system for introducing fluid into each compartment, where the device forms, upon filing the compartments, to a curved shape conforming to a natural three-dimensional kidney shape of the stomach. In one aspect, a method for deploying a gastric balloon structure in a gastric cavity includes determining dimensions of the gastric cavity in a feeding state, selecting a fill volume for each of a number of isolated chambers of the balloon structure, and filling each chamber while the balloon structure is in the gastric cavity. In one aspect, a system for treating obesity includes a means for conforming a flexible, space-filling structure to a natural kidney shape of the gastric cavity, a means for maintaining at least two isolated inflatable regions of the flexible, space-filling structure, and a means for introducing fluid into each inflatable region.

In one aspect, a gastric balloon structure includes multiple isolated non-concentric inflatable chambers and a valve system for introducing fluid into each chamber, where the structure assumes, upon inflating, a curved shape conforming to a natural three-dimensional kidney shape of the gastric cavity.

A fluid delivery device includes a tube coupled to an axial manipulator. The axial manipulator includes an elongate member arranged to move axially in a housing. The tube is in fluid communication with a fluid diverter which is arranged to move axially in the housing upon axial movement of the elongate member. Seals are provided to prevent fluid from leaking out of the housing. A fluid port is in fluid communication with the tube via the fluid diverter, such that fluid can flow in and out of the tube via the fluid port and the fluid diverter.
