A gastroesophageal reflux preventer and related methods are provided. A gastroesophageal reflux preventer is configured to be positioned around the exterior of a body organ and may include an elongate portion including a plurality of nodes positioned along at least a portion of the length of the elongate portion.

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.

Inflatable medical devices and methods for making and using the same are disclosed. The inflatable medical devices can be medical balloons. The balloons can be configured to have a through-lumen or no through-lumen and a wide variety of geometries. The device can have a high-strength, non-compliant, fiber-reinforced, multi-layered wall. The inflatable medical device can be used for angioplasty, kyphoplasty, percutaneous aortic valve replacement, or other procedures described herein.

A method of using an implantable device provides an implantable device including a plurality of links (113, 115, 117, 119), a device closure pin (111), a lock-in unit (103) attached and located between two links, and a quick release unit (105) attached and located between two links. The plurality of links (113, 115, 117, 119), lock-in unit (103) and release unit (105) are constructed in a closed contour. The closed contour of the implantable device, in a rigid state (151), is a figure eight comprised of two arcs (125, 127) and two connected interconnecting sections (131, 133).

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.

A gastric diverter and a digestive tract support and a release method thereof. The digestive tract support has undeployed shape and deployed shape, and includes upper support, lower support and connecting member. In the deployed shape, a first opening is provided at top of the upper support, a second opening is provided at bottom thereof, and the lower support is disposed below the upper support; a third opening is provided at top of the lower support, a fourth opening is provided at bottom thereof, and the upper support and the lower support are connected by a plurality of connecting members; the fourth opening of the lower support is connected to a membrane tube, the deployed upper support and lower support both cannot pass through an open gastric pyloric orifice, and the connecting members can pass through the gastric pyloric orifice or be placed at the gastric pyloric orifice.

A food reflux reducing two-piece nasogastric tube includes a first tube body and a second tube body. The first tube body has a first connector on one end, and a protrusion edge on an outer side of the first connector in adjacent to the first positioning portion. The first connector has a through hole having a seal portion in adjacent to the first positioning portion. The seal portion has a cross break. A convex portion is on an inner edge of the through hole between the seal portion and the first positioning portion. The second tube body has one end provided with a second connector and an insertion combination tube extending therefrom. Two elastic arms extend from an outer side of the second connector and comprise a hook portion respectively. Thus, the second tube body is efficiently connected with and removed from the first tube body.

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.

The present disclosure provides an intragastric implant capable of inducing the feeling of satiety from inside the stomach, together with a delivery device for delivering said implant. The system and method provides greater access to minimally invasive weight loss procedures for patients who are only overweight or obese, reducing the risks associated with more invasive procedures.
