Abstract: The invention is directed to a device for the sealing occlusion and/or for the space-filling tamponade of hollow organs or other cavities in the human body, comprising a preferably fully and residually formed balloon (2) which applies a sealing pressure that is as constant as possible to the wall of the organ to be occluded or tamponaded. The device comprises an isobarically acting regulator (3) for the filling pressure within the interior of the balloon, the regulator having a volume reservoir (3) situated extracorporeally outside of the body, and a feed line (6) for communicatively connecting the extracorporeal volume reservoir of the regulator to the interior of the balloon. The connecting feed line between the balloon and the regulator has a flow-directing one-way valve (26) that prevents backflow from the balloon to the volume reservoir of the regulator, while a nonflow-directing throttle element (27) is provided which allows a slow volume compensation between the balloon and the volume reservoir.

Abstract: A device (1) for the tracheal intubation of and the administration of ventilation to a patient for rapid volume-compensating sealing of the trachea, wherein the sealing surfaces of a preferably fully and residually formed balloon-like film body (4) abut the wall of the trachea with a sealing pressure of the balloon (4) which is as constant as possible and follow the thoracic pressure acting on the balloon with the least possible time latency with regard to corresponding fluctuations of the balloon inflation pressure, and the trachea is kept sealed under such dynamic fluctuations or respiration synchronously alternating fluctuations of the balloon inflation pressure. This is enabled by a defined large lumen (7, 5) supply of the balloon inflation medium, the supplying lumen being measured in such a way that a sealing pressure-maintaining extracorporeal volume compensation that works in a time synchronous manner can be achieved in the sealing balloon element.

Abstract: The invention relates to devices (1) for draining or closing a natural or artificial bladder outlet by means of a balloon body (3) made of preferably micro-scale thin-walled Polyurethane, which has a vesical anchor, is transurethrally sealing and is extended into the urethra or through the urethra. According to the invention, the balloon body is seated on a shaft body (2) supporting the balloon, and the filling of the balloon body is preferably done with air.

Abstract: A tamponade for nasal cavities or sinus cavities for tamponading a cavity of the nasal tract in the region of an ostium leading to the cavity with uniform force, comprising a thin-walled balloon which is made from a soft foil-like, only slightly expandable, smoothly folding polyurethane material, with a wall thickness in the range of 5 to 50 ?m, which is already completely shaped with the required tamponade dimensions or greater at the time of production, and can therefore be expanded without application of filling pressure, and said balloon occupies the respective, generally irregular-shaped cavity and the ostium of same when in the filled condition, through the development of forces that are as uniform as possible on the structures exposed to the balloon in such a way that a distal segment of the balloon is located inside the cavity where a tamponade is to be applied, a proximal segment of the balloon is located upstream of the cavity and a transostial segment of the balloon extends through the ostium and c

Abstract: A device and a method for the thermal reshaping of hose blanks from preferably pre-extruded elastic raw hose material, wherein during the reshaping, the hose blank is arranged in a shell-like, single- or multi-piece molding tool with a hollow body, wherein the tempering of the molding tool that is necessary for reshaping occurs by means of clamp-like tempering elements which are shaped congruently to the outer surface of the mold and which close form-fittingly over the mold, while the molding tool itself does not comprise any tempering system at all, in particular no ducts or other hollow spaces for circulating a tempering medium, and wherein the temperature of each tempering element is kept constant during the process, while, to modify the temperature of the molding tool, a different tempering element with a correspondingly constant temperature is positioned against the molding tool.
