Abstract: An anchor (20) for anchoring a tube (10) with respect to a pylorus of a patient. The tube (10) may be a bypass tube or bypass conduit for bypassing a portion of the bowel. The anchor (20) may comprise a gastric bulb (22) collapsible for introduction and optionally self-expanding to an operative condition. The bulb (22) may have an open structure of a low pressure chamber. The bulb (22) may be configured to partly collapse in response to stomach contractions. This enables the bulb to exhibit compliance with the stomach contractions, and absorb the contractions. Other embodiments of tubes, anchors, balloons, and stapling, are also described.

Abstract: A device (10) for treatment of obesity or diabetes comprises a duodenal tube (12), first anchor (14) arranged at a pre-defined distance (D) from a proximal end (15) of the duodenal tube (12). The first anchor (14) is adapted for anchoring the tube (12) distally to the pylorus (P) without mucosal involvement. A second anchor (17) in the form of a conical, inflatable balloon is used for anchoring the device (10) in the stomach (S) of the patient. The duodenal tube (12) is flexible and can be arranged in the duodenum (D) and in the jejunum (J) of the patient.

Abstract: An overtube that includes a body, a first duct for housing a first insertion tube of a first endoscope, where the first duct is arranged longitudinally within the body and opens at the distal end, a second duct for housing a second insertion tube of a second endoscope, where the second duct is arranged longitudinally within the body and opens at the distal end, a first orifice for introducing the first insertion tube into the first duct, a second orifice for introducing the second insertion tube into the second duct, a third orifice for introducing a lubricant into the first duct and into the second duct, and where the first duct and the second duct communicate with each other via a communication passage, and the passage opens at the third orifice.

Abstract: The invention relates to a system (1) for binding a shoe (2) to a foot rest (3) of a rowing boat, said shoe (2) having a sole (21) and said foot rest (3) being likeable to a plate having an underside (9) and a top surface (8). The main feature of a binding system according to the invention is that it comprises at least one mobile stop (6) projecting from the top surface (8) and a rigid actuating lever (4) projecting from the underside (9), and in that said lever (4) is connected to said at least one stop (6) in such a way that movement of said lever (4) causes said at least one stop (6) to move between a deployed position in which it becomes lodged in a recess (22) in the sole (21), and a retracted position in which it leaves said recess (22) and allows the shoe (2) to be detached from the foot rest (3).

Abstract: The invention relates to a system (1) for binding a shoe (2) to a foot rest (3) of a towing boat, said shoe (2) having a sole (21) and said foot rest (3) being likeable to a plate having an underside (9) and a top surface (8). The main feature of a binding system according to the invention is that it comprises at least one mobile step (6) projecting from the top surface (8) and a rigid actuating lever (4) projecting from the underside (9), and in that said lever (4) is connected to said at least one stop (6) in such a way that moment of said lever (4) causes said at least one stop (6) to move between a deployed position in which it becomes lodged in a recess (22) in the sole (21), and a retracted position in which it leaves said recess (22) and allows the shoe (2) to be detached them the foot rest (3).
