摘要： A gastric bypass device includes an occlusion device that is adapted to be deployed relative to a patient's pyloric sphincter and a liner that extends distally from the occlusion device. A tether extends from the occlusion device. A dynamic leash may be secured relative to the occlusion device and may work in conjunction with the tether to help hold the occlusion device in place.

摘要： 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.

摘要： A gastrointestinal device for treating obesity includes a three-dimensional porous structure configurable between a compressed pre-deployment configuration to facilitate delivery and an expanded post-deployment configuration. The porous structure includes a first opening at its proximal end and a larger second opening at its distal end. The porous structure also includes a sleeve coupled to its distal end. Optionally, the device further includes a suture at the proximal end of the wire mesh structure to facilitate retrieval and an anti-migration component positioned at the junction of the porous structure with the sleeve. The porous structure is deployed in a patient’s stomach such that the anti-migration component sits proximal to the patient’s pylorus and prevents migration of the entirety of the device into and through the pylorus. The sleeve extends through the pylorus, into the duodenum and ends in the duodenum or jejunum. Food enters the device from the first opening at the proximal end of the porous structure, passes through the porous structure and sleeve, and exits at the distal end of the sleeve. The device treats obesity by providing a relatively immovable volume occupying structure in the stomach and a bypass for food past the pylorus and proximal portion of the small intestine. Optionally, the device further acts to slow the passage of food through the digestive tract. Patients with the device experience satiety more quickly and have a prolonged sensation of satiety.

摘要： A retrieval device comprising a hook assembly and a capsule assembly. The hook assembly has an attachment feature at a first end. The capsule assembly includes a capsule, a capsule shaft, and a handle connected in series and defining an inner bore. The capsule has a first end defining an opening. The inner bore of the capsule assembly is configured to slidably receive the hook assembly. The handle has a central portion, a first extension portion attached to the capsule shaft, and a second extension portion with a hook assembly lock at a second end. The hook assembly lock is configured to lock the hook assembly to the second extension portion. The second extension portion is configured to pull the hook assembly relative to the capsule shaft, and the first extension portion is configured to push the capsule shaft relative to the hook assembly along the central longitudinal axis.

摘要： A gastric calibration tube includes a flexible elongate member, a pushing member, and a balloon member. The flexible elongate member has a proximal end portion, a distal end portion, and an outer surface that extends between the proximal and distal end portions. The outer surface defines a side opening. The flexible elongate member defines a lumen that is in communication with the side opening. The pushing member has a proximal portion and a distal portion. The distal portion is advanceable through the lumen of the flexible elongate member and out of the side opening of the flexible elongate member. The balloon member is secured to one or both of the flexible elongate member and the pushing member. The balloon member is inflatable to fix the gastric calibration tube within a patient's stomach.

摘要： A suprapyloric anchor assembly includes an antral cap having at least three stabilizing members configured to reside in an antrum and engage tissue circumscribing a pyloric valve. A duodenal member is configured to reside at least partially in a duodenal bulb, and one or more tethers connect the antral cap to the duodenal member. The tether(s) is/are configured to allow passage of stomach contents through the pyloric valve. Optionally, one or more gastric balloon(s) may attached to the suprapyloric anchor and be inflated with the gastric cavity.

摘要： The present invention relates to gastric obstruction device deployment systems and a device for intermittently obstructing a bodily opening, such as a gastric opening, and includes a proximal occluding member connected to a distal occluding member by a tether. The proximal occluding member is formable from an elongated and narrower configuration to a contracted or expanded but wider configuration. When employed in the stomach, the gastric obstruction device may be arranged transluminally with the distal occluding member disposed in the duodenum and the proximal occluding member disposed against the pyloric valve, intermittently occluding the pyloric valve and preventing or delaying the flow of gastric contents through the pyloric valve.

摘要： A gastric implant includes a distal sleeve portion configured to be disposed in a duodenum of a patient, and a pyloric restriction portion connected to a proximal end of the distal sleeve portion. The pyloric restriction portion is configured to be disposed in a pylorus of a patient. Also, the implant includes a proximal anchor portion connected to a proximal end of the pyloric restriction portion. The proximal anchor portion is configured to be disposed in a lower stomach of the patient. The proximal anchor portion has at least one eyelet for fastening to the stomach to secure the implant to the gastrointestinal tract.
