Abstract

The inserted sleeve seals a vein or artery containing fistulae, aneurysmata etc. It comprises a strong ductile spiral support (3), adjacent turns of which are bridged by elastic material impervious to liquid. Typically this can consist of a hose fitting closely round the support. Alternatively, separate spiral supports can be contained in the hose only at the ends. USE/ADVANTAGE - Keeps the passage in the blood vessel free while sealing off fistulae etc.

Description

Die Erfindung betrifft ein Stent zur Abdichtung von Gefäßen bei arteriovenösen Fisteln oder Gefäßwandaussackungen im arteriellen Bereich (Aneurysmata). The invention relates to a stent for sealing vessels with arteriovenous fistula or Gefäßwandaussackungen in the arterial portion (aneurysms).

Aus der US-PS 48 20 298 ist ein spiralförmiger Stent bekannt. From US-PS 48 20 298, a spiral stent is known. Dieser bekannte Stent besteht im wesentlichen aus einem spiralförmigen Kern, wobei die Zwischenräume zwischen zwei Spiralwindungen mit einem elastischen Faser-Netzwerk überbrückt sind. This known stent essentially consists of a spiral core, wherein the spaces between two spiral turns are bridged with an elastic fiber network. Dieser bekannte Stent ist dazu ausgelegt, ein unter Umständen lebensbedrohliches Aneurysma zu überbrücken. This known stent is designed to bridge a life-threatening circumstances aneurysm. Hierzu weist der Spiralkern eine hinreichende Formfestigkeit auf, um die Gefäßwände zu stabilisieren. For this purpose, the spiral core to form a sufficient strength to stabilize the vessel walls. Nach der Implantation kann körpereigenes Gewebe in das erwähnte elastische Netzwerk zwischen den Spiralwindungen einwachsen und so eine Abdichtung der Aussackung bewirken. After implantation, the body's own tissue can grow between the spiral windings and effect a sealing of the aneurysm in the mentioned elastic network.

Wenn dieser bekannte Stent auch bei einigen Indikationen zufriedenstellende Ergebnisse eines operativen Eingriffs ermöglicht, wird es als nachteilig empfunden, daß eine Abdichtung der überbrückten Gefäßteile erst sekundär durch das Einwachsen von Körpergewebe erzielt wird. If this known stent also with some indications allows satisfactory results of surgery, it is felt to be disadvantageous that a sealing of the bridged vessel parts is only secondarily achieved by ingrowth of tissue.

Vor dem aufgezeigten Hintergrund ist es nun die Aufgabe der vorliegenden Erfindung, einen Stent der eingangs erwähnten Art so weiterzubilden, daß er nicht nur das Lumen eines Gefäßes aufrecht erhält, sondern auch Aneurysmata oder Fisteln zu verschließen vermag. Before the indicated background, it is now the object of the present invention to develop a stent of the type mentioned such that it receives not only the lumen of a vessel upright, but also aneurysms or fistulas is able to close.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale der Ansprüche 1 sowie 3. This object is achieved by the characterizing features of claims 1 and 3rd

Demnach besteht der Stent gemäß einem ersten Vorschlag aus einem spiralförmigen Träger hoher Verformbarkeit und Stabilität, dessen benachbarte Spiralwindungen durch ein elastisches Material flüssigkeitsundurchlässig überbrückt sind. Accordingly, the stent is according to a first proposal of a spiral-shaped support high ductility and stability whose adjacent spiral turns are bridged by an elastic liquid-impermeable material.

Die spiralförmige Ausbildung des Trägers verleiht ihm einerseits eine hohe Verformbarkeit, die seine Implantierfähigkeit erst ermöglicht. The spiral design of the carrier adds one hand a high deformability, which only allows its Implantierfähigkeit. Andererseits bietet die Spiralform eine genügende Festigkeit, um die Gefäßwände zu stabilisieren. On the other hand, the spiral shape provides sufficient strength to stabilize the vessel walls. Das benachbarte Spiralwindungen überbrückende Material weist eine hinreichende Elastizität auf, um den notwendigen Bewegungen des Stents beim Implantieren standhalten zu können, ohne zu reißen. The neighboring spiral turns bridging material has a sufficient elasticity to withstand the necessary movements of the stent during implantation, without tearing.

Das elastische Material kann als Schlauch ausgebildet sein. The elastic material may be formed as a hose. In diesem Falle umhüllt es den Träger, eng an dessen Spiralwindungen anliegend, als Einheit flüssigkeitsdicht. In this case, it envelops the carrier tightly against the spiral turns, liquid-tight as a unit.

Gemäß dem zweiten Vorschlag besteht der Stent aus einem Schlauch aus flüssigkeitsundurchlässigem Material, in dessen beiden Enden jeweils ein spiralförmiger Träger hoher Verformbarkeit und Stabilität eingesetzt ist, der von dem Schlauch eng anliegend umhüllt ist. According to the second proposal is the stent from a tube of liquid impermeable material, in both ends of which a spiral carrier high ductility and stability is used, which is tightly enveloped by the hose. Auch bei diesem Stent sind die Spiralwindungen der Träger durch das Schlauchmaterial überbrückt. Also in this stent the spiral turns of the support are bridged by the hose material. Im Gegensatz zu dem ersten Vorschlag ist das schlauchförmige Material aber nicht armiert in dem Abschnitt zwischen beiden Trägern. In contrast to the first proposal, the tubular material is not reinforced in the section between the two carriers. Dieser Stent kommt vorzugsweise dort zum Einsatz, wo die zu überbrückende Strecke relativ kurz ist. This stent is preferably used in applications where the distance to be bridged is relatively short.

Der bzw. die Träger bestehen vorteilhafterweise aus einem körperverträglichen Metall. The carrier are advantageously made of a biocompatible metal. Alternativ ist aber auch die Verwendung eines körperverträglichen Kunststoffs möglich. Alternatively, however, the use of a biocompatible plastic is possible.

Als elastisches Material für die Überbrückungen bzw. für den Schlauch eignet sich jedes einschlägige Material. As the elastic material for the bridging or for the tube, each relevant material is suitable. Vorteilhaft ist die Verwendung von Latex. the use of latex is advantageous.

Die Erfindung wird kurz anhand zweier Ausführungsbeispiele gemäß der Zeichnungen näher erläutert. The invention will be briefly explained with reference to two embodiments according to the drawings.

Hierbei zeigt: Here shows:

Fig. 1 eine Ausführungsform des Stents gemäß dem ersten Vorschlag Fig. 1 shows an embodiment of the stent according to the first proposal

Fig. 2 eine Ausführungsform gemäß dem zweiten Vorschlag. Fig. 2 shows an embodiment according to the second proposal.

Der Stent 1 gemäß Fig. 1 weist einen spiralförmigen Träger 3 auf. The stent 1 of Fig. 1 comprises a spiral-shaped support 3. Die Formfestigkeit dieser langen Spirale gewährleistet es, daß das Lumen eines mit dem Stent 1 zu versehenden Gefäßes offengehalten wird. The dimensional stability of these long spiral, it ensures that the lumen of a percarbonate with the stent 1 is kept open vessel.

Der Träger 3 ist hier umhüllt von einem elastischen Schlauch, der aus einem flüssigkeitsundurchlässigen Material besteht. The carrier 3 is here surrounded by an elastic hose, which consists of a liquid impervious material. Der Schlauch liegt eng an dem spiralförmigen Träger 3 an. The tube is located closely to the helical support. 3

Der Stent 1 ′ gemäß Fig. 2 besteht aus einem Schlauch 2 ′ aus flüssigkeitsdichtem Material. The stent 1 'shown in Fig. 2 consists of a tube 2' of liquid-tight material. In seine beiden Enden sind spiralförmige Träger 3 ′, 3 ′′ gesetzt. In its both ends are spiral-shaped supports 3 ', 3' set '. Die Spiralwindungen der Träger sind von dem Material des Schauches 2 ′ eng umhüllt. The spiral turns of the support are tightly enveloped by the material of the Schauches 2 '.

Nach der Implantation des Stents in das zu behandelnde Gefäß tritt sofort eine Abdichtung beispielsweise einer Gefäßwandaussackung ein. After the implantation of the stent in the vessel to be treated immediately sealing occurs, for example a Gefäßwandaussackung. Die sofort eintretende Abdichtung ist insbesondere bei der Behandlung von Fisteln erwünscht und notwendig. The seal immediately entering is particularly desirable in the treatment of fistulae and necessary.
