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.

Tissue expanders and methods of their manufacture and use are disclosed herein. A tissue expander shell according to the present disclosure may include a shape and topography that facilitates uniform or substantially uniform expansion and contraction of the tissue expander. In at least one example, the shell may include a series of topographical features, such as ridges, grooves, channels, valleys, canals, protrusions, pleats, creases, or folds. In some embodiments, these features may have a curved or wavy cross sectional profile. For example, the shell may include a series of concentric curved ridges.

Devices and methods for treating obesity are provided. More particularly, intragastric devices and methods of fabricating, deploying, inflating, monitoring, and retrieving the same are provided.

An apparatus for the treatment of acid reflux disease comprising two or more movement restriction device segments adapted to be assembled movement restriction device of a controlled size. The assembled 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.

A bariatric clamp may include substrate members overmolded in polymer forming first and second elongated portions, a bight portion having a flexible hinge, one or more inflatable portions disposed at least partially along interior sections of the first and second elongated portions; and a port coupled to at least one of the inflatable portions and configured to adjust inflation of the inflatable portions. The inflatable portions are provided to assist in retaining the clamp in a closed position to partition the stomach and to adjust a pressure of the clamp when partitioning the stomach.

A gastric restrictive device including two separate elongated rigid members, at least two elongated inflatable paddings respectively along the two elongated rigid members, at least one flexible and extendable hollow tube fluidly interconnecting the at least two elongated inflatable paddings at inner ends thereof, and a two-part interlocking mechanism at outer ends of the two elongated rigid members. The at least one flexible and extendable hollow tube being bendable to fold the two elongated rigid members towards each other into a closed configuration with the two elongated inflatable paddings parallel and opposing each other and with the two-part interlocking mechanism interlockable. The device is attachable to a stomach and the at least two elongated inflatable paddings are inflatable by injecting fluid through the at least one flexible and extendable hollow tube for partially restricting the stomach without damaging the stomach tissue and with maintaining normal physiological functions of the stomach.

Valve assemblies for use with expandable devices that are positioned within remote cavities and more particularly relates to the catheters/conduits used to inflate these devices with fluid.

Systems and methods for treating eating disorders using electro-physiologically active transducer intragastric balloon system (“EAT system”) are described herein. The EAT System includes an intragastric balloon that is configured to operate in a typical fashion and further modified to include an integrated electro-physiological stimulation unit. The stimulation unit is configured to generate impulses using a transducer that are suitable for stimulating sensory receptors located around the stomach. In particular, transducer transmits mechanical waves through the fluid within the IG balloon and its outer shell to any receptors of the vagus nerve system that are located in the vicinity of the IG balloon. Controlled stimulation of the vagus nerve fibers using the stimulation unit can effectively produce appetite controlling sensations of satiety beyond the typical efficacy period of an unmodified IG balloon.

For desorptive technique, inhibiting hunger and reducing the amount of food ingested, besides avoiding the contact of the food with part of the intestine, working for the weight reduction of the patient and associated diseases such as type 2 diabetes. For this, a gastrointestinal device (10) formed from an intragastric ring (1) made of malleable and expandable material, extends a tubular sleeve (3) with or without a stent. The gastrointestinal device (10) has its inlet valve (4) attached to a catheter (CA) for gastrointestinal implant, and is directed into the stomach (L) of the patient, where an endoscopic forceps (EP) or the stent directs the tubular sleeve (3) through the pyloric canal (P), into the duodenum (D), and unfolding until it occupies part of the intestine. Therefore, the intragastric ring (1) is positioned near the Pyloric canal (P), inside the stomach (E), and is then inflated and expanded by fluid—liquid, gas or air, assuming the shape of a balloon.

Disclosed are devices, assemblies, and systems for delivering and deploying a gastric obstruction device and methods of operation thereof. A system for deploying a gastric obstruction device can comprise a housing comprising a gear mechanism; a control component coupled to the gear mechanism; a delivery tube coupled to the housing, wherein a distal end of the delivery tube is configured to be positioned within the gastric obstruction device; and a control tube coupled to the gear mechanism within the housing, wherein the control tube extends through the delivery tube lumen and is configured to engage with the gastric obstruction device, wherein the control tube is configured to rotate in response to a rotation of the control component, and wherein the rotation of the control tube is configured to rotate the gastric obstruction device.
