A technique is described for reducing the stomach cavity endoscopically, from within the stomach or, in the alternative, from within the peritoneal cavity via a wall of the digestive tract. This new approach for reducing gastric capacity uses a flexible endoscope and a specially adapted ligating loop that is secured at spaced locations about an inner periphery of the stomach. After attachment, the loop is constricted to draw together the associated gastric wall portions to reduce the food receiving cavity defined at the base of the esophagus. The ligating loop is preferably a slip knotted loop.

There is provided a flexible guide tube which guides an endoscope or a therapeutic device into an abdominal cavity through the mouth and stomach to conduct an observation or a therapeutic treatment in the abdominal cavity. The guide tube includes an insertion section which has a distal end, a peripheral section, and a central axis, and which is capable of being inserted into a body through the mouth, and two expandable and shrinkable balloons arranged in the vicinity of the distal end at a predetermined distance from each other in the axial direction on the periphery of the insertion section. The predetermined distance is preferably set to 3 to 8 mm, and the length of the insertion section is preferably set to about 600 to 1000 mm.

An adjustable size balloon at the distal end of a feeding tube is used to aid in positioning, along with an endoscope, the tube in the jejunum or small bowel of a patient, without creating an obstruction in the intestines. The balloon is fully inflated when the endoscope that is used to place the tube in the duodenum is withdrawn, and then partially deflated to a size that allows peristaltic action on the balloon to move the tube into the jejunum, after which the balloon is further deflated to avoid creating an obstruction in the intestine.

The endoscopic system includes an endoscope having an insertion portion which is inserted into a body and has a forceps insertion duct, and a light emitting member which has an end portion that emits the light and is inserted into a hollow organ in the body through the forceps insertion duct of the endoscope. The light emitting member issues positional information of the hollow organ which is detected through the endoscope orally and gastrically inserted into an abdominal cavity by causing the end portion to emit the light in the hollow organ. The system includes a treatment instrument by which a treatment is conducted in the abdominal cavity in cooperation with the endoscope.

A biliary stent has a number of smooth-surfaced wings extending radially outwardly from a central region and extending longitudinally along substantially the entire length of the stent. A securement barb is located at one end of the stent and extends generally radially outwardly toward a side of the stent in cantilevered fashion at an angle less than or equal to 90. The securement barb is angled such that it presents an outward-facing half-arrowhead profile. At least one end of the stent is smoothly or conically tapered. In one embodiment, the wings extend linearly along the stent; in another embodiment, the wings extend helically along the stent. Either embodiment may have a pigtail configuration at one or both ends.

There is provided an endoscopic system. The system comprises a flexible endoscope insertable into a first tubular organ from a natural opening of a human body. The system further comprises an opening member which forms on a wall part of the first tubular organ an opening used to insert the endoscope into an abdominal cavity from the first tubular organ in the body, an anastomosing member which is able to anastomoses the first tubular organ with a second tubular organ in the abdominal cavity, and a cutting member with which the second tubular organ is able to be cut.

There is provided an anastomosis system for performing an anastomosis in a body. The system includes an anastomosis button, which has two foldable flange portions and a tubular main body portion extending between the flange portions, for coupling two lumen portions in the body to each other, and a housing which can receive the anastomosis button as the flange portions are folded. The system further includes a guide, which has a distal end to be inserted through a patient's mouth to a target portion in the body and a proximal end arranged outside the body, for guiding the housing to the target portion. A release line having a distal end to be inserted to the target portion along the guide and a proximal end held outside the body is operated, whereby the anastomosis button can be ejected from the housing and be held at the target portion.

A novel approach to diagnostic and therapeutic interventions in the peritoneal cavity is described. More specifically, a technique for accessing the peritoneal cavity via the wall of the digestive tract is provided so that examination of and/or a surgical procedure in the peritoneal cavity can be conducted via the wall of the digestive tract with the use of a flexible endoscope. As presently proposed, the technique is particularly adapted to transgastric peritoneoscopy. However, access in addition or in the alternative through the intestinal wall is contemplated and described as well. Transgastric and/or transintestinal peritoneoscopy will have an excellent cosmetic result as there are no incisions in the abdominal wall and no potential for visible post-surgical scars or hernias.
