Inflation devices for inflating intragastric devices and associated systems and methods are disclosed herein. In several embodiments, an inflation device can include a tube, an inner detent, and an outer detent. The tube can extend from a proximal portion of the inflation device to a distal portion of the inflation device, and can include a handle at the proximal portion and a barb at the distal portion. The barb can have a cross-sectional dimension greater than a cross-sectional dimension of a corresponding inflation port of an intragastric device. The inner detent can be positioned over the barb and can include a mating interface. The outer detent can be positioned over the inner detent, and can be configured to attach over a proximal cap of the intragastric device. The tube can be longitudinally advanceable relative to at least one of the inner and outer detents,

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 gastric restraining device for treating excessive weight or obesity in mammals. The gastric restraining device includes an elastomeric sheet configured to be placed around a stomach of a mammal, an ablation device attached to the elastomeric sheet, the ablation device configured to emit energy toward an outer surface of the stomach when the elastomeric sheet is placed around the stomach, and an energy device coupled to the ablation device to generate the energy and to transfer the energy to the ablation device.

The present disclosure provides an inflatable weight control device that is implanted long-term with an endoscope in obese and bariatric human patients to promote early and prolonged satiety. The device includes a flexible member coupled to a valve body assembly and an elongated durable module residing within the flexible member. The flexible member is selectively inflated to form two bulbs with a central passageway extending through the bulbs and the valve body assembly. Once the bulbs are inflated, the device is retained within the patient's pyloric valve to form a gastric outlet obstruction wherein chyme accumulates and then is directed through the central passageway to reach the patient's duodenum. Due to its unique configuration, the implanted device reduces gastric outflow which results in early and prolonged satiety when the patient consumes normal-sized meals or food portions, thereby reducing food consumption and increasing the patient's weight loss.

The invention relates surgical abdominal methods of treating a reflux disease in a patient by implanting a movement restriction device that, when implanted in a patient, restricts the movement of the stomach notch in relation to the diaphragm muscle preventing the cardia to slide up through the diaphragm hiatus opening. Also disclosed is a laparoscopic instrument for providing a movement restriction device to be invaginated in the stomach fundus wall of a human patient to treat reflux disease.

Transoral obesity treatment devices and related methods for operation thereof are described which occupy space within a stomach and/or stimulate the stomach wall. The transoral obesity treatment devices and related methods are intended to assist a patient in maintaining a healthy body weight. Features of the devices include insertion transorally and without invasive surgery, without associated patient risks of invasive surgery, and without substantial patient discomfort. The life span of these devices may be material-dependent upon long-term survivability within an acidic stomach, but is intended to last one year or longer. The devices have the capacity to vary in size and are desirably self-actuating in that they change shape and/or volume using internal motors or actuators. The changing character of the devices helps prevent the person's stomach from compensating for the implant, such as sometimes happens with static intragastric devices.

A sealing device attached to an intragastric balloon device having a head flexibly attached to a body by a pivot portion, where the pivot portion provides the head with a closed state and an open state relative to the body and the intragastric device. The sealing device having one or more plugs configured to seal an aspiration port of a lumen when the head is in a closed state and further configured to release the aspiration port of the lumen when the head is in an open state.

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. Furthermore including a stretching device to stretch a portion of the stomach wall to further affecting the patient's appetite.

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.
