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.

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 folded expandable gastro-retentive device and its uses in human medical care include, inter alia, appetite suppression in a subject in need thereof. The expanded device can be included in kits.

Methods, devices and systems for delivering a device assembly into a gastric or other space within the body, allowing the device to expand to occupy volume within the gastric space and, after an effective period of time, delivering a substance or stimulus to begin breakdown of the expanded device so that it may release from the body.

The present invention relates to gastric obstruction device deployment systems and a device for intermittently obstructing a bodily opening, such as a gastric opening, and includes a proximal occluding member connected to a distal occluding member by a tether. The proximal occluding member is formable from an elongated and narrower configuration to a contracted or expanded but wider configuration. When employed in the stomach, the gastric obstruction device may be arranged transluminally with the distal occluding member disposed in the duodenum and the proximal occluding member disposed against the pyloric valve, intermittently occluding the pyloric valve and preventing or delaying the flow of gastric contents through the pyloric valve.

An expandable intragastric device, configured for being positioned into the stomach by an endoscopic procedure is provided. The device is capable of assuming a minimum-encumbrance configuration for delivery into the stomach and an expanded configuration for use in situ. The device also includes a balloon structure, which is capable of assuming a deflated configuration for delivery into the stomach and an inflated configuration for occupying a part of the stomach inner space. The overall configuration of the device is such that, once it is delivered in the stomach, food passes into the inner lumen of the supporting tubular body and into the intestine.

An implant configured for ingestion by a patient. After the implant has been swallowed by the patient and is disposed within the target location, e.g. the patient's stomach, an inflation subcomponent causes the implant to expand from a compact delivery state to an expanded, volume-occupying, deployed state. In the deployed state the implant creates a sensation of satiety in the patient stomach and thereby aids in limiting food intake and obesity. After a predetermined time a deflation subcomponent is actuated and the implant reduces in size so as to allow it to pass through the remainder of the patient's digestive track. The device may further incorporate tracking and visualization subcomponents, as well as pharmaceutical delivery subcomponents.

A method for performing a sleeve gastrectomy includes providing a first medical device including a tube for insertion into an interior of a stomach, the tube having a proximal end and a distal end, and a shaping portion positioned at the distal end of the tube, providing an inflation lumen, and providing a second medical device, the second medical device being a stapler or clamp positioned externally on the stomach laterally adjacent to the first medical device. The method also includes introducing positive pressure into the stomach via the inflation lumen, defining a resection line for the sleeve gastrectomy, and clamping the stomach using the second medical device. The resection line is defined at least partially by the position of the second medical device relative to the first medical device when a predetermined positive pressure range is provided via the inflation lumen.

A bariatric balloon system for reducing the volume of the stomach, featuring a plurality of balloons each fluidly connected to a tube with a tube port at its end. The system is secured to the abdominal wall. The system can be implanted such that the port is outside the skin or is under the skin. The tube extends through the skin and/or muscle and fat to the stomach wherein the balloons are placed. The balloons can be inflated by introducing fluid such as saline to the tube via the port.

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.
