An endoscopic sleeve gastroplasty procedure comprises forming a gastric sleeve (5) through a stomach (1) by suturing a first portion (9) of a wall (3) of the stomach (1) to a second portion (11) of the wall (3). First and second rows (20, 22) of first and second mounds (18, 19) are formed in the first and second portions (9,11) by injecting a viscus bulking solution (25) into a submucosal layer (28) at sites (17) of the wall (3) to form pockets (27) therein to form the first and second mounds (18, 19). Sutures (15) are inserted into respective pairs (16) of the first and second mounds (18, 19) with anchor bars (38) of the sutures (15) located in the corresponding pockets (27). The sutures (15) are tightened for drawing the first and second mounds (18, 19) together to in turn draw the first and second portions (9, 11) of the wall (3) of the stomach (1) together to form the gastric sleeve (5).

The present invention relates to a reflux disease treatment apparatus, comprising two or more movement restriction device segments adapted to form an implantable movement restriction device with an elongated shape that maintains cardia in the correct position. The movement restriction device has proximal and a distal end, wherein the distal end is adapted to stabilize and hold the proximal end. The invention further comprises a control device for controlling the stimulation device to stimulate the cardia sphincter. The distal end can be further adapted to treat obesity, for example by stretching the wall of the stomach or filling out a volume of the stomach.

A method of performing bariatric surgery includes inserting a gastrectomy device into a stomach of a patient, positioning the gastrectomy device in a selected location in the stomach, transecting a portion of the stomach thereby reducing a size of the stomach, and applying a reinforcement scaffold to an outer surface of the stomach. The reinforcement scaffold is configured to maintain the reduced size of the stomach.

A staple housing includes an array of staples each in a staple delivery position or ready position ready to be fired into target tissue. A staple driver is advanceable to drive the ready-position staples from the staple head into the tissue using staple pushers. During use, the staples in the ready positions are simultaneously fired into the target tissue using the staple pushers, forming an array of staples in the target tissue. After the array has been fired, one or more feed mechanisms within the staple housing advance a second group of staples from one or more staple storage locations into the ready positions in preparation for firing of the second group of staples.

An adjustable band or clamp or non-adjustable clamp is placed about the greater curvature of the stomach in a vertical orientation. The band or clamp completely compartmentalizes the stomach between a small vertical pouch and the fundus and body of the stomach. The fundus and body of the stomach are excluded from nutrients and are separated from a long narrow channel where the food travels. A small passage at the level of the antrum allows gastric juices to empty from the fundus and body of the stomach. The clamp may be applied during open surgery in laproscopic surgery or using a single port technique, or through any natural orifice in NOTES (Natural Orifice Transluminal Endoscopic surgery) or using a hybrid surgical technique.

One or more medical devices may be provided that may be used, for example, in bariatric surgery including a vertical sleeve gastrectomy. Occlusion devices can be integrated with a catheter or tube to occlude one or more proximal or distal landmarks of a stomach and a stapling guide may be used to occlude a lateral boundary of the stomach to define a cavity. A volume of the potential resultant sleeve may be determined by inserting fluid or gas into the catheter or tube, measuring pressure, and calculating the volume of the cavity.

The present invention provides devices and methods for attachment of an endolumenal gastrointestinal device, such as an artificial stoma device, a gastrointestinal bypass sleeve or other therapeutic or diagnostic device, within a patient's digestive tract. In one application of the invention, an endolumenal bypass sleeve is removably attached in the vicinity of the gastroesophageal junction to treat obesity and/or its comorbidities, such as diabetes. The bypass sleeve may be at least partially deployed by eversion.

A method for treating a patient includes creating at least one incision to gain access to an peritoneal cavity, performing a gastric volume reduction procedure and introducing a device to prevent gastric contents from interacting with at least a portion of the duodenum.

Apparatus for endoscopic anastomosis of the stomach and the bowel of a patient to allow food to bypass the duodenum and optionally a portion of the jejunum comprising a tube, surgical apparatus and at least one operating element. The tube is insertable into the stomach and has a proximal end and a distal end. The surgical apparatus is at least partially, preferably completely, insertable through the tube. The operating element, for operating the surgical apparatus from the proximal end, is connected or connectable to the surgical apparatus. The surgical apparatus is configured for establishing anastomosis between a first area of the stomach and a second area of the bowel.

One or more medical devices may be provided that may be used, for example, in bariatric surgery including a vertical sleeve gastrectomy. The one or more medical devices may include a laparoscopic sleeve gastrectomy stapling guide in conjunction with a calibration tube in accordance with one or more examples. According to an example, the calibration tube may be a flared, multi-diameter calibration tube. The flared, multi-diameter calibration tube may have a first diameter along a portion of the tube and a second diameter that may larger than the first diameter along at least another portion of the tube. The calibration tube may be used in conjunction with the stapling guide to align stomach such that it may be stapled along the stapling guide (e.g., to perform the vertical sleeve gastrectomy).
