Abstract

An insertion sleeve (12) for an ultrasound catheter (10) is provided with a balloon. The ultrasound catheter (10) can be inserted into the bronchial system through a duct located inside the balloon-armed insertion sleeve (12), filled with a contact gel and provided at the proximal and distal ends with a gasket (sluice). At the examination site, the balloon (16) is filled with water through a second working duct (14) and a circular contact surface with the bronchial wall is thus established, allowing a sonographic representation to be obtained which was previously not possible.

Description

Die Darstellung der tracheobronchialen Wandstrukturen war mit den bisher in der Medizin zur Verfügung stehenden bildgebenden Verfahren nicht möglich.The representation of the tracheobronchial wall structures was similar to that in the previous Imaging methods available to medicine are not possible.

Bei der endokopischen Untersuchung des Tracheobronchialsystems kann nur die Oberfläche bzw. Schleimhaut betrachtet werden, Kernspin- und Computertomo­ graphie als moderne Schnittbildverfahren erzielen keine ausreichende Auflösung.In the endocopic examination of the tracheobronchial system, only that Surface or mucous membrane are considered, nuclear spin and computer tomos Graphics as modern cross-sectional imaging methods do not achieve sufficient resolution.

Die Entwicklung von miniaturisierten Ultraschallsonden erlaubt seit einigen Jahren die intravaskuläre Anwendung und somit hochauflösende Schnittbilddar­ stellung der Gefäßwandstrukturen und Charakterisierung unterschiedlicher Ge­ fäßwandläsionen. Die in diesem Fall natürliche, jedoch immer erforderliche Wasservorlaufstrecke ist hierbei das Blut. Im Tracheobronchialsystem muß eine Wasservorlaufstrecke erst geschaffen werden.The development of miniaturized ultrasound probes has allowed for some Years of intravascular application and thus high-resolution sectional image position of the vessel wall structures and characterization of different ge vascular wall lesions. The natural one in this case, but always necessary The water inlet is the blood. In the tracheobronchial system, one Water supply route can only be created.

Mit dem hier vorgestellten Bronchialkit wird das Problem der nicht vorhandenen Wasservorlaufstrecke gelöst, indem der Ultraschallkatheter in eine einfach, steril und billig herzustellende, mit Ultraschallgel gefüllte Kunstoffhülle eingeführt wird, in der über einen zweiten Arbeitskanal ein Ballon auf Höhe des Ultraschallkristalls mit einer Mischung aus Wasser und Kontrastmittel gefüllt werden kann. Damit kann die Tracheobronchialwand analog der Gefäßwände dargestellt und pathologische Prozesse in der Wand selbst sowie in den angrenzenden Ge­ weben erfaßt werden. Wandinfiltrierende Tumore und mediastinale Lymphkno­ tenmetastasen (um nur einige Beispiele zu nennen) werden damit einer differen­ zierten Bildgebung zugänglich. Außerdem kann der teure und nicht-sterilisierbare Ultraschallkatheter, der deswegen im Gefäßsystem nur einmal verwendet werden kann, mehrfach eingesetzt werden, so daß durch diesen Bronchialkit eine ein­ fache, effektive und billige Untersuchungstechnik zur Verfügung steht. The bronchial kit presented here eliminates the problem of nonexistent Water flow path solved by turning the ultrasound catheter into a simple, sterile and introduced inexpensive to manufacture, ultrasonic gel filled plastic cover a balloon at the level of the ultrasonic crystal is located in a second working channel be filled with a mixture of water and contrast medium can. This means that the tracheobronchial wall can be displayed analogously to the vessel walls and pathological processes in the wall itself as well as in the adjacent ge weaving can be detected. Wall infiltrating tumors and mediastinal lymph nodes Ten metastases (to name just a few examples) thus become different graceful imaging accessible. In addition, the expensive and non-sterilizable Ultrasound catheter, which is therefore used only once in the vascular system can be used several times, so that a bronchial kit simple, effective and cheap examination technique is available.  

Den Systemaufbau entnehmen Sie bitte der beigefügten Konstruktionszeichnung, der bereits kommerziell verfügbare, bisher nur intravaskulär einsetzbare Ultraschall­ katheter ist nur schematisch dargestellt.The system structure can be found in the attached construction drawing, the ultrasound, which is already commercially available and has so far only been used intravascularly Catheter is shown only schematically.
