Abstract: A connector device for gastric calibration hoses, including a first end and a second end opposite the first end. A first connector is disposed at the first end and a second connector is disposed at the second end. The first and the second connector are connected with each other via a fluid channel. The first connector includes a first tapering cavity sized and shaped to receive and couple with a gastric calibration hose. The second connector includes a second tapering cavity and a tapering recess annularly surrounding the second tapering cavity. The second tapering cavity and the tapering recess are sized and shaped to alternatively couple with different medical devices by receiving therein tubular structures of the different medical devices.

Abstract: In a gastric calibration hose with an elongated flexible hollow body having an outer wall and a first and a second hose end, it is provided that the elongated flexible hollow body has at least two channels, each of which extend in the longitudinal direction of the hollow body, the first channel having at least one opening in the area of the second hose end, and the second channel being closed at the second hose end, at least one illuminant being arranged in the second channel in the area of the second hose end.

Abstract: In a connector device for gastric calibration hoses includes a first and an opposite second end, wherein a first connector is formed at the first end and a second connector is formed at the second end, wherein the first and the second connector are connected with each other via a fluid channel, and wherein the first connector includes at least one first tapering cavity into which gastric calibration hose may be plugged for coupling, it is provided that for coupling different medical devices, the second connector has at least one second tapering cavity and at least one, tapering recess annularly surrounding the second cavity, so that, for coupling, the different medical devices may selectively be plugged into the second tapering cavity or into the tapering recess.

Abstract: In a closing means for longitudinally extending hollow organs having a flexible wall and a passage, comprising at least one balloon-like chamber with a chamber volume, the chamber volume being variable by the supply of a fluid, and the passage of the hollow organ being partly or completely closable depending on the chamber volume, it is provided that a fastening device is arranged at the chamber, by which the chamber may be fastened to an outer part of the wall, parts of the wall of the hollow organ being adapted to be folded around the rectilinear chamber and to be fastened to the chamber or to each other such that the chamber, when in the fastened condition, is arranged in a fold in the wall of the hollow organ.
