The invention relates to an intraluminar method of treating a reflux disease in a patient by implanting a device comprising an movement restriction device that, when implanted in a patient, fills a volume in the patient's abdomen that is close to and at least partially above the patient's cardia when the patient is in a standing position. The invention further relates to a method of restoring the location of the cardia in a patient suffering from a reflux disease and to an instrument suitable to use with intraluminar method and/or restoration method. Also disclosed are instruments treating a patient suffering hiatal hernia and providing a movement restriction device to be invaginated in the stomach fundus wall.

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 gastrointestinal implant device (2800) comprises a planar proximal element (220) configured to reside in a stomach to resist distal migration, a distal element (222) configured to reside in an intestine to resist proximal migration and one or more tethers (224) coupling the planar proximal element to the distal element.

The present disclosure provides an inflatable weight control device that is implanted long-term with an endoscope in obese and bariatric human patients to promote early and prolonged satiety. The device includes a flexible, inflatable member coupled to a valve body assembly and an elongated durable module residing within the flexible member. The flexible member is selectively inflated to form two bulbs with a central passageway extending through the bulbs and the valve body assembly. Once the bulbs are inflated, the device is retained within the patient's pyloric valve to form a gastric outlet obstruction wherein chyme accumulates and then is directed through the central passageway to reach the patient's duodenum. Due to its unique configuration, the implanted device reduces gastric outflow which results in early and prolonged satiety when the patient consumes normal-sized meals or food portions, thereby reducing food consumption and increasing the patient's weight loss.

According to exemplary embodiments of the present disclosure, devices, systems, and methods for pyloric occlusion in an endoscopic procedure may include a first flange and a second flange connected to the first flange by a saddle region having a lumen. The second flange may be proximal to the first flange. The pyloric occlusion device may further include a closure element. The closure element may be configured to occlude a flow of material through the lumen, including across the pylorus when deployed. The closure element may be a closure of the lumen by rotation of one of the first or second flanges about the saddle region relative to the other of the first or second flange.

A valve device includes a valve, a scaffold connected coaxially to an external surface of the valve, a luminal prosthesis that is adapted to be implanted into a lumen of a patient, with the scaffold and the valve removably attachable inside of the luminal prosthesis.

The present disclosure relates generally to stents, systems, and methods for anchoring devices within a body lumen by cooperation between the device and the body musculature. A device comprising an elongate tubular member may be deployed within a body lumen, where the body lumen includes a sphincter that regulates flow through the body lumen. The elongate tubular member includes a sleeve formed from a flexible membrane and one or more stents disposed at either or both ends of the sleeve. In some embodiments, the stents may be treatment stents configured to treat a portion of the body lumen. The elongate tubular member may be deployed within the body lumen such that the flexible membrane aligns with and moves in coordination with the sphincter, thereby increasing retention forces acting upon the elongate tubular member when the sphincter is closed to minimize treatment stent migration.

The invention relates surgical abdominal methods of treating obesity in a patient by implanting a volume filling device that, when implanted in a patient, reduces the food cavity in size by a volume substantially exceeding the volume of the volume filling device. Also disclosed is a laparoscopic instrument for providing a volume filling device to be invaginated in the stomach wall of a human patient to treat obesity.

An volume filling device for treatment of obesity is placed outside the stomach wall of the patient to reduce the inner volume of the stomach, thereby affecting the patient's appetite. By providing the volume filling device outside the stomach wall, contact with stomach acids is avoided, thereby increasing the life of the device.

A gastroscopic method of implanting a device for treating obesity of a patient by the device being postoperatively and non-invasively regulated to actively stretch a portion of the stomach wall of the patient to actively create a feeling of satiety. The method comprising the steps of: inserting the stretching device into the stomach of the patient through the esophagus, inserting the operation device into the body of the patient, the operation device being adapted to be connected to the stretching device, placing the stretching device in contact with the stomach wall, and fixating the stretching device to the stomach wall such that the operation device can regulate the device for actively stretching the portion of the stomach wall to actively create a feeling of satiety in the patient.
