The present invention relates to methods and devices that help to curb appetite and / or reduce food intake. In one embodiment, the methods and devices of the present invention include a small intestinal / duodenal insert comprising an elongated member with at least one flow reduction element that can cause the stimulation of one or more biological signals of satiety.

Apparatus is provided for use in a stomach of a subject. The apparatus includes a gastric balloon and an anchor coupled to the gastric balloon. The anchor includes a flexible tube, which, when in a relaxed position, is shaped so as to define a portion that prevents the anchor from passing into a duodenum of the subject. The anchor also includes one or more shape-controlling elements coupled to the portion and configured to control a shape of the portion. Other embodiments are also described.

The invention relates to the field of medical equipment and application thereof, and provides a duodenum internal covering film. The duodenum internal covering film is made of biocompatible biodegradable or non-biodegradable material or / and hydrophobic material and is mainly composed of an elastic ampullar portion and a tubular portion. The ampullar portion comprises a biocompatible bionic micro array adhesion piece which can achieve strong adhesion in the force application direction, does not stab intestine tissues and is capable of achieving detachment and recovery easily. The adhesion piece is good in stability, strong in adaptability to material and shapes, good in self-cleaning performance, free of damage and pollution to the intestine tissues, and capable of achieving repeated adhesion and detachment and supporting other components mutually in functions. When intestinal tract contents move, the internal covering film can not be detached due to the fact that subvertical pulling force does not exist. When the duodenum bulb is expanded and inflated, the internal covering film can not be detached due to the fact that the internal covering film does not have opposite and subvertical pulling force, and in the process of recovery, the internal covering film can be detached and recovered easily through force applied in a subvertical mode. The duodenum internal covering film can be manufactured into the medical equipment which does not damage the intestine tissues and can prevent and cure fat and diabetes.

The invention provides an internal tectorial membrane for duodenum, and relates to a built-in degradable medical instrument in a digestive tract. The internal tectorial membrane can be made of biocompatible materials by electrospinning. The internal tectorial membrane is placed in the duodenum of a patient, not only can stop food from contacting with the intestinal mucosae of the patient during dissection, but also avoids affecting functions of cells of the intestinal mucosae physiologically, can be obtained by hybrid electrospinning or / and multi-layered electrospinning or / and core-shell electrospinning or / and dry-method electrospinning, and can be manufactured into a medical instrument which can reduce injury, prevent dropping, avoid being removed and restrain bounce and can be used for treating diabetes mellitus and adiposis.

The invention relates to a transpyloric device for accepting chyme from the stomach and conducting said chyme on in a bypass-like manner through a patient's duodenum; said device is held in place by balloon segments which sit on a preferably radially collapsible and self-erecting transpyloric conducting element; the filling level of the balloon segments, and thus the axial sealing force acting primarily on the shoulder surfaces of the pylorus or the surrounding area thereof, can be adjusted by the user, and the force applied to the stomach and duodenum structures adjoining the pylorus is reduced to a level that is permanently bearable for the organs even when the filling pressure of the segments rolling against each other is elevated. The invention also relates to an applicator for putting a bypass device of said type in place in the region of the transition from the stomach to the duodenum.

An endoscopically-deployable tissue-manipulation device including an elongate, generally tubular outer body having a proximal portion and a distal end portion that may be configured as sufficiently flexible to traverse the working channel of a flexible endoscope (e.g., side-viewing duodenoscope). The outer body may include an outer body lumen extending longitudinally between the proximal and distal portions. An anchoring structure of the device will include an elongate inner body that may extend through the outer body lumen and be configured to include a first linkage member attached to the inner body, a second linkage member that is pivotably attached to the first linkage member and to the outer body.
