Abstract: The present invention relates to a device and a method for alternately measuring the thoracic and pleural pressure and for gastropharyngeal or tracheal sealing, wherein the balloon component of a tube or catheter placed in the trachea or oesophagus alternates between two filling or functional states, wherein the filling state of the balloon component in the measuring mode assumes a value of constant, defined volume during the measurement, said value corresponding to a flaccid filling state, and the filling state of the balloon in the oesophageally or tracheally sealing functional mode maintains a constant, sealing pressure specified by the user.

Abstract: The invention is directed to a catheter-like system which dwells temporarily or even continuously in the body of a patient and which serves for the closed delivery and/or discharge of odour-intensive substances, wherein the release of foul-smelling substances is reduced to the greatest possible extent by the system wall having a multi-layer structure that incorporates a proportion of barrier materials, and an odour-neutral decompression of gaseous fractions arising in the body and discharged into the system is ensured. The system comprises in particular a structure like a tubular film, by which an internal space to be reached in the body is connected to a container, arranged outside the body, for receiving the respective substances that are to be delivered and/or discharged. At the end positioned inside the body, the tube structure is provided with a retaining and/or sealing balloon element, which secures the system in the body.

Abstract: The invention describes a specific, multilayer tubular film for the manufacture of catheter devices that are usable in the most odor-neutral manner possible. The passage of substances through the film wall may be reduced or avoided by incorporating suitable barrier layers. The delivery of strong-smelling active substances and also the discharge of intensely odorous excretions or secretions may be optimized in a problem-solving manner by proportional layers of EVOH- or PVDC-based materials, for example, in the multilayer film structure. The invention combines these barrier layers with mechanically loadable carrier layers made of polyurethane (PUR), PVC, or also polyamide (PA) or PA-related material layers, for example.

Abstract: The invention relates to a multi-layer balloon film material in which one or more layers of an elastically deforming material is/are combined with one or more layers of a plastically deforming non-elastic material, wherein the non-elastic layer counteracts the straightening properties of the elastic layer in the case of planar folds or bends in the balloon film material. In particular, the cross-sectional area of eyelet- or channel-shaped structures which conducts secretions or fluids, which structures typically occur in the area of wrinkle-like invaginations of a residually sized balloon film in an organ lumen or a body cavity, can be reduced and, particularly in the case of cyclically changing filling pressures of the balloon, can be stabilized in such a way that an optimally sealing closure or tamponade effect is achieved across the largest possible filling pressure amplitudes.

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.

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.
