Die Erfindung betrifft eine Vorrichtung zum Abdichten eines von Flüssigkeit oder Gas durchströmbaren Hohlgefäßes mit einem rohrartigen und in das Hohlgefäß einbringbaren Transportkörper.The invention relates to a device for sealing a liquid or gas flowable hollow vessel with a tubular and in the Transportable hollow body.
Insbesondere in der Medizin ist es üblich, daß bei Beseitigung von Ablagerungen in Arterien oder Venen medizinische Geräte eingesetzt werden, mit denen diese Ablagerungen z. B. abgehobelt werden. Während dieses Vorganges kann ein Teil der Ablagerungen (Späne) von strömenden Blut mitgerissen und in andere Blutbahnen transportiert werden, was unerwünscht ist.In medicine in particular, it is common for the removal of Deposits in arteries or veins medical devices are used with which these deposits z. B. be planed. During this The process can be part of the deposits (chips) of flowing blood carried away and transported to other bloodstream, which is undesirable is.
Ausgehend von dem obigen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, hier Abhilfe zu schaffen und eine Vorrichtung vorzuschlagen, die für kurz- oder langdauerndes, vollständiges oder teilweises, reversibles Blockieren oder Abdichten eines Hohlgefäßes, z. B. Blutgefäß, Aneurysma, Körperhöhle, Kanalisationsröhre, Hydraulikrohr etc. geeignet ist, und zwar an einer Stelle, die nur indirekt und durch natürliche oder künstliche, vorbestehende oder durch neugeschaffene Hohlwege erreicht werden kann.Starting from the above prior art, the object of the invention based on remedying this situation and proposing a device for short or long term, complete or partial, reversible blocking or sealing a hollow vessel, e.g. B. blood vessel, aneurysm, body cavity, Sewer pipe, hydraulic pipe, etc. is suitable, in one place, which only indirectly and through natural or artificial, pre-existing or can be achieved through newly created ravines.
Die gestellte Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.The object is achieved by the features of Claim 1 solved.
Die Vorrichtung im "geöffneten" Zustand (Mittel in Betriebsstellung) verhindert im Hohlgefäß vollständig oder teilweise das Strömen oder Verbleiben oder Eindringen oder Weiterbefördern von Flüssigkeit, Gas, Feststoffen, oder Mischungen von Flüssigkeit und/oder Gas und/oder Feststoffen.The device in the "open" state (middle in operating position) prevented all or part of the flow or remaining in the hollow vessel Penetration or transfer of liquid, gas, solids, or Mixtures of liquid and / or gas and / or solids.
Weitere zweckmäßige und vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Further expedient and advantageous embodiments of the invention go from the subclaims.
An der gewünschten Stelle des Hohlgefäßes wird das Mittel in seiner Form so verändert, daß es ein größeres Volumen einnimmt oder eine größere Fläche abdeckt und das umgehende Hohlgefäß damit ganz oder teilweise ausfüllt oder an dieser Stelle eine Barriere bildet. Dazu reicht es, wenn das Mittel aus dem Transportkörper herausgefahren wird. Danach kann das Mittel wieder in seinen ursprünglichen Zustand zurückversetzt werden, womit seine Wirkung aufgehoben wird. In einer Ausführungsform der Erfindung kann das Mittel im "teilweise geöffneten" oder "geöffnetem" Zustand vom restlichen Teil der Vorrichtung abgekoppelt und wieder angekoppelt werden. Die in Volumen oder Fläche veränderbaren Mittel bestehen aus einem oder mehreren Werkstoffen, die durch ihre Beschaffenheit und/oder Anordnung und/oder Verarbeitungsart die Eigenschaft und/oder das Bestreben haben, das Volumen und/oder die Fläche des Mittels mit oder ohne Energiezufuhr (mechanische Kraft) zu vergrößern (z. B. superelastische Legierung, Memory-Shape-Legierung, Federgeflecht, Kunststoff usw.). Das Mittel hat im Betriebszustand regelmäßig die Form z. B. eines Rotations-ellipsoides (Rugby-Ball, Zitrone), einer Karotte oder eines spitz zulaufenden Schlauchs. Mindestens ein Ende der Vorrichtung bleibt in allen Funktionszuständen in der am wenigsten Raum oder Fläche beanspruchten Form. Von diesem Ende her können die entfalteten Mittel wieder von einem Schlauch/Rohr durch Überschieben in die komprimierte Form zurückgefahren werden. Die veränderlichen Mittel der Erfindung können beispielsweise an der Spitze einer langen, dünnen Sonde befestigt und im "geschlossenen" Zustand mit einem die Sonde konzentrisch umschließenden Schlauch/Rohr so bedeckt sein, daß die Mittel möglichst wenig Raum/Fläche beanspruchen. Durch Abziehen des Schlauches/Rohres von der Spitze weg dehnen sich die Mittel aus und streben den Kontakt mit dem umgebenden Hohlgefäß an. Durch Vorschieben des Schlauches/Rohres (Transportkörper) schiebt sich dieses über die Komponente und drängt diese wieder in ihre komprimierte Form. Die Mittel können dicht und/oder gelocht und/oder geschlitzt und/oder geflochten und/oder beschichtet sein und/oder aus Strahlen und/oder Spiralen und/oder Ringen bestehen, die optional miteinander verbunden sein können. Dabei kann die Vorrichtung auch so ausgebildet sein, daß es festes Material im Inneren der schlauchförmigen, "geöffneten" veränderlichen Mittel auffängt und im "geschlossenen" Zustand zurückbehält.At the desired location of the hollow vessel, the shape of the agent is so changed that it takes up a larger volume or a larger area covers and completely or partially fills the surrounding hollow vessel or forms a barrier at this point. It is sufficient if the remedy from the Transport body is moved out. After that, the remedy can be in its to be restored to its original state, reducing its effect will be annulled. In one embodiment of the invention, the agent in "partially open" or "open" state of the rest of the Device disconnected and reconnected. The in volume or Surface changeable means consist of one or more materials, by their nature and / or arrangement and / or type of processing have the property and / or aspiration, the volume and / or the Area of the agent with or without energy supply (mechanical force) too enlarge (e.g. super elastic alloy, memory shape alloy, Spring braid, plastic, etc.). The agent has regular in the operating state the shape z. B. a rotation ellipsoid (rugby ball, lemon), a carrot or a tapered hose. At least one end of the device remains in the least space or area in all functional states claimed form. From this end, the deployed means can again from a hose / tube by pushing it into the compressed form be reduced. The variable means of the invention can for example attached to the tip of a long, thin probe and in "closed" state with a concentrically enclosing the probe The hose / tube must be covered so that the means as little space / area as possible claim. By pulling the hose / tube away from the tip the means expand and strive for contact with the surrounding Hollow vessel. By advancing the hose / tube (transport body) pushes this over the component and pushes it back into its compressed form. The means can be tight and / or perforated and / or slotted and / or braided and / or coated and / or from rays and / or spirals and / or rings, which are optional with each other can be connected. The device can also be designed that there is solid material inside the tubular, "opened" catches variable means and retains them in the "closed" state.

In den Figuren ist jeweils eine Vorrichtung 10 zum Abdichten eines von Flüssigkeit oder Gas durchströmbaren Hohlkörpers 12 mit einem rohrartigen und in das Hohlgefäß 12 einbringbaren Transportkörper 14 dargestellt, in dem Mittel 16 zur Sperrung bzw. Behinderung des Flüssigkeitsdurchflusses sowie Betätigungsmittel 18 für diese Mittel 16 untergebracht sind, durch die die Mittel 16 zwischen einer Betriebsstellung, in der sie den Durchfluß der Flüssigkeit im Hohlgefäß 12 behindern, und einer Ruhestellung, in der sie im Transportkörper 14 untergebracht sind, verstellbar sind. Der Transportkörper 14 ist elastisch verformbar und in Richtung der Längsachse des insbesondere rohrartigen Hohlgefäßes 12 anpaßbar. Dabei kann der Transportkörper 14 aus Kunststoff oder Metall bestehen. Man erkennt, daß das Betätigungsmittel 18 in Form eines Zug- und/oder Druckseiles ausgebildet ist, dessen eines Ende mit den Mitteln 16 in Wirkverbindung steht, während das andere Ende vom Benutzer betätigbar ist. Die Mittel 16 können aus einem Werkstoff bestehen, der bestrebt ist, sein Volumen und/oder seine Fläche zu vergrößern. Dabei besitzen die Mittel 16 in ihrem Betriebszustand die Form eines rotationssymmetrischen Körpers, der wulstartig oder korbartig ausgebildet sein kann. Ferner ist von Bedeutung, daß die Mittel 16 z. B. aus einer Formgedächtnis-Legierung und/oder einem Federgeflecht und/oder Kunststoff bestehen können und so beschaffen sind, daß sie ohne zusätzliche bzw. aufwendige Mittel von der Ruhestellung in ihre Betriebsstellung und zurück überführbar sind. Im Rahmen dieses Erfindungsgedankens können die Mittel gelocht und/oder geschlitzt und/oder geflochten und/oder beschichtet sein und/oder aus Strahlen und/oder Spiralen und/oder Ringen bestehen.The figures each show a device 10 for sealing a hollow body 12 through which liquid or gas can flow, with a tubular transport body 14 which can be inserted into the hollow vessel 12 and in which means 16 for blocking or obstructing the liquid flow and actuating means 18 for these means 16 are accommodated through which the means 16 are adjustable between an operating position in which they hinder the flow of the liquid in the hollow vessel 12 and a rest position in which they are accommodated in the transport body 14 . The transport body 14 is elastically deformable and adjustable in the direction of the longitudinal axis of the tube-like hollow vessel 12 in particular. The transport body 14 can consist of plastic or metal. It can be seen that the actuating means 18 is designed in the form of a pull and / or push rope, one end of which is operatively connected to the means 16 , while the other end can be actuated by the user. The means 16 can consist of a material which strives to increase its volume and / or its area. In their operating state, the means 16 are in the form of a rotationally symmetrical body which can be bead-like or basket-like. It is also important that the means 16 z. B. from a shape memory alloy and / or a spring braid and / or plastic and are such that they can be transferred from the rest position to their operating position and back without additional or expensive means. Within the scope of this inventive concept, the means can be perforated and / or slotted and / or braided and / or coated and / or consist of rays and / or spirals and / or rings.
In den Fig. 4 und 5 ist die Vorrichtung Teil einer medizinischen Sonde 20 mit Führungsdraht 22, die teilweise als Transportkörper genutzt wird. Wird das Mittel 16 aus der Sonde 20 herausgefahren (Fig. 4b), dann entspannt es sich und steht mit dem Hohlgefäß 12 in Druckverbindung, so daß es den Durchfluß der im Hohlkörper 12 strömenden Flüssigkeit sperrt bzw. diesen behindert. In Fig. 5 ist das Mittel 16 in Form eines Korbes ausgebildet, der ebenfalls rotationssymmetrisch ausgebildet ist, so daß er sich genauso an die Innenwand des Hohlgefäßes 12 andrücken kann. Die Fig. 7 und 8 zeigen Querschnitte durch die Vorrichtung mit oder ohne Sonden. Andererseits zeigen die Fig. 1-6 und 8 Varianten von Sonden ohne Arbeitskanal, während die Fig. 7, 9 und 10 Sonden mit Arbeitskanal 24 darstellt. Die Fig. 9, 10 stellt eine Möglichkeit dar, die Erfindung mit einem bestehenden anderen Instrument zu kombinieren.In Figs. 4 and 5, the device is part of a medical probe 20 with guide wire 22, which is partly used as a transport body. If the means 16 is moved out of the probe 20 ( FIG. 4b), it relaxes and is in pressure connection with the hollow vessel 12 , so that it blocks the flow of the liquid flowing in the hollow body 12 or impedes it. In Fig. 5, the means 16 is in the form of a basket, which is also rotationally symmetrical, so that it can also press against the inner wall of the hollow vessel 12 . FIGS. 7 and 8 show cross-sections through the device with or without probes. On the other hand, FIGS. 1-6 and 8 show variants of probes without a working channel, while FIGS. 7, 9 and 10 show probes with a working channel 24 . FIGS. 9, 10 is one way to combine the invention with an existing other instrument.
