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.

A gastrointestinal bypass device for directing food and liquids from an esophagus and/or a proximal portion of a stomach into an intestines is described. The device comprises a receiver, a sleeve, and a device coupling. The receiver may be configured to be positioned in the esophagus and/or the stomach. A proximal portion of the receiver may be configured to open and close to at least partially conform to an inside of the esophagus and/or a proximal portion of the stomach. The receiver may be configured to receive food and liquids from the esophagus and/or a proximal portion of the stomach into a lumen of the receiver. The sleeve may be coupled to a distal portion of the receiver. The sleeve may be configured to be positioned in the stomach and the intestines. The sleeve may have a lumen in communication with the lumen of the receiver. The sleeve may be configured to direct the food and the liquids from the receiver into the intestines. The device coupling may be coupled to the distal portion of the receiver and/or a proximal portion of the sleeve. The device coupling may be configured to be coupled to one or more tissue anchors.

The present invention provides gastrointestinal devices for limiting transfer and contact of material across luminal walls along a segment of the gastrointestinal tract (e.g., at the duodenum and/or upper jejunum). Devices of the invention include a gastrointestinal sleeve, an anchor, and a flange for attachment to a luminal wall proximal to the pyloric orifice. The invention also provides methods of use associated with such gastrointestinal devices, including methods for delivery, removal, and treatment of metabolic disorders, such as type 2 diabetes, non-alcoholic steatohepatitis, non-alcoholic fatty liver disease, obesity, and related comorbidities thereof by implanting gastrointestinal devices.

The invention described herein relates to telescoping stents. The embodiments described herein allow for adequate securement to, accommodation for movement by, and prevention of injury of tubular organs or hollow areas of the body. Certain embodiments relate to telescoping steins with loop interlocking mechanisms. Further embodiments relate to telescoping stents with ball-in-groove interlocking mechanisms.

An intragastric device includes an elongated member having a proximal end and a distal end and an anchor connected to the elongated member. The anchor includes a stem, a first arch and a second arch, and a curvilinear element. The stem includes a proximal end and a distal end. The distal end of the stem is attached to the proximal end of the elongated member. Each arch has first and second ends and a proximal peak therebetween. The first end of each arch is attached to the proximal end of the stem, and the second end of each arch extends radially away from the stem. The curvilinear element connects the second end of the first arch to the second end of the second arch.

A bypass device may include an elongate member extending from a proximal end toward a distal end, and a proximal opening and a distal opening coupled to one another by a lumen disposed through the elongate member. The bypass device also may include at least one port extending through a side surface of the elongate tubular member, wherein at least a portion of the bypass device may be bioabsorbable.

A device for use in bariatric surgery includes a flexible hollow tube extending from a proximal end to a distal end and defines a channel therebetween. A series of openings is defined in a distal portion of the tube allowing for fixation of tissue using suction. A flexible member has an initial position disposed alongside the tube and is deployable to a subsequent position in which the flexible member engages a greater curvature of a stomach. The flexible member is configured to be deployable to automatically assume a shape of a greater curvature of a stomach. The flexible member includes a bulging region and a tapering region when deployed. The flexible member is releasably attached to the distal end of the tube.

A medical tool for placement in a digestive tract lumen includes a tubular portion, which opens at two ends, and an annular attachment portion, which is configured to be fixed to at least a part of the tubular portion and be capable of installing the tubular portion in the digestive tract lumen. The tubular portion is placeable along the digestive tract, has a side surface that is capable of conforming to the shape of the inner wall of the digestive tract, and allows digestive juice or digested contents to permeate. The attachment portion is configured to be placeable in the stomach through the mouth.

An intestinal device, or a non-constrictive cuff, is configured for placement around an intestine. In the closed position the non-constrictive cuff is configured to be around at least part or all of an intestine, wherein the non-constrictive cuff does not constrict the portion of the intestine when deployed. A first intestinal device can be deployed for placement around a portion of an intestine, wherein a proximal end of the first intestinal device is configured to longitudinally overlap a distal end of a second intestinal device when disposed around an intestine. A method of use for a first intestinal device or non-constrictive cuff is also disclosed.

A gastrointestinal system includes a bracelet type anchor constructed and arranged to reside in a body cavity, a gastrointestinal sleeve configured to expand under a load and contract when the load is removed and a string connecting a bracelet type anchor with the sleeve. Pulling the string transforms the bracelet type anchor from a flexible mode into a rigid state.
