Devices and methods for tissue acquisition and fixation, or gastroplasty, are described. Generally, the devices of the system may be advanced in a minimally invasive manner within a patient's body, e.g., transorally, endoscopically, percutaneously, etc., to create one or several divisions or plications within the hollow body organ. Such divisions or plications can form restrictive barriers within a organ, or can be placed to form a pouch, or gastric lumen, smaller than the remaining stomach volume to essentially act as the active stomach such as the pouch resulting from a surgical Roux-En-Y gastric bypass procedure. Moreover, the system is configured such that once acquisition of the tissue by the gastroplasty device is accomplished, any manipulation of the acquired tissue is unnecessary as the device is able to automatically configure the acquired tissue into a desired configuration.

A device (10) for treatment of obesity of a patient comprises an annular element (12) having a relatively large outer boundary and a relatively small inner boundary, and an elongated flexible tube (14) extending from the relatively small inner boundary of the annular element to a distal end. The relatively large outer boundary is adapted to be attached to an inner wall of a stomach (100) of a patient, such that the annular element divides the stomach (100) into two chambers, an esophagus-end chamber close to an esophagus of the patient, and a pylorus-end chamber close to a pylorus of the patient. The invention also provides a method for treatment of obesity of a patient which includes inserting an annular element having a relatively large outer boundary and a relatively small inner boundary into a stomach of the patient, and attaching the relatively large outer boundary of the annular element to an inner circumference of the stomach of the patient.

An endoscopic device separates ingested food from gastric fluids or gastric fluids and digestive enzymes, to treat obesity. In a particular embodiment a gastric bypass stent comprises a tubular member and two or more stent members defining a lumen. The tubular member has a substantially liquid impervious coating or covering and one or more lateral openings to permit one-way liquid flow.

Methods and devices for simulating a gastric bypass and reducing the volume of the stomach involve placing a tubular liner along the lesser curve of the stomach cavity. Also, methods and devices for slowing gastric emptying involve placing valves within the stomach cavity near the gastro-intestinal junction and / or the pylorus. These methods and devices may prevent a patient from drinking and eating large volumes at one time and from eating slowly all day.

A system and method for endoscopically forming an anastomosis between two naturally adjacent points in the digestive tract. The system and method utilizes elongate magnetic devices that, when connected across a tissue boundary, necrose tissue until an anastomosis forms and the devices are passed naturally. Despite the elongate shape of the devices, the resulting anastomosis is substantially round. As such, round anastomoses can be formed having increased diameters merely by increasing the lengths of the devices, obviating the need for wider endoscopes.

A system and method for treating obesity including a first instrument containing a first magnet therein, the first instrument insertable into a stomach of a patient and the first magnet deployable into the stomach of the patient and having a first space. A second instrument contains a second magnet therein, the second instrument insertable into a bowel of a patient and the second magnet deployable into the bowel of the patient and having a second space. A stent is insertable into the first and second spaces to maintain an opening formed between the stomach and bowel.

The invention provides pharmaceutical compositions, methods for the treatment of, and related diagnostics and computer-implementable systems that relate to, the treatment of a variety of metabolic syndromes, including hyperlipidemia, weight gain, obesity, insulin resistance, hypertension, atherosclerosis, fatty liver diseases and certain chronic inflammatory states. In an additional aspect of the invention, compositions and methods of treatment are calibrated to the ileal brake response to surgical intervention e.g. RYGB, as both activate the ileal brake, which acts in the gastrointestinal tract and the liver of a mammal to control metabolic syndrome manifestations and thereby reverse or ameliorate the cardiovascular damage (atherosclerosis, hypertension, lipid accumulation, and the like) resulting from progression of metabolic syndrome. The net benefit is the potential to treat all of the common manifestations of metabolic syndrome, including T2D and obesity, with one medicament, which contains glucose as an activation agent for the ileal brake. The ileal brake is the controller for progression of metabolic syndrome, and both RYGB surgery and the oral formulation act beneficially on the metabolic syndrome manifestations via this pathway. Disclosed as well are combination medicaments that act synergistically on the ileal brake and the manifestations of metabolic syndrome.In other aspects, the invention provides ileal brake hormone releasing compositions, methods of treatment, diagnostics, and related systems useful in selective control of appetite, stabilizing blood glucose and insulin levels, and treating gastrointestinal disorders in a similar manner to RYGB surgery, but having at least 20% of the potency to stimulate the hormonal response of the ileal brake of humans.
