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 in arteriovenous fistulas or Vascular wall sagging in the arterial area (Aneurysmata).

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

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 well-known stent also in some Indications satisfactory results of a surgical intervention, it is considered felt disadvantageous that sealing the bridged parts of the vessel only secondarily through the Body tissue ingrowth is achieved.

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.Against the background shown, it is now the Object of the present invention, a stent type mentioned so that he  not only maintains the lumen of a vessel, but also aneurysms or fistulas can close.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale der Ansprüche 1 sowie 3.This task is solved by the characteristic Features of claims 1 and 3.

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 based on a first one Proposal from a spiral carrier high Deformability and stability, its neighboring Spiral turns through an elastic material are liquid-impermeable.

Die spiralförmige Ausbildung des Trägers verleiht ihm einerseits eine hohe Verformbarkeit, die seine Implantierfähigkeit erst ermöglicht. Andererseits bietet die Spiralform eine genügende Festigkeit, um die Gefäßwände zu stabilisieren. 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 spiral shape of the support gives on the one hand a high deformability, which is his Implantability made possible. On the other hand the spiral shape offers sufficient strength to stabilize the vessel walls. The neighboring Spiral bridging material has a sufficient elasticity to the necessary Withstand stent movements during implantation to be able to do without tearing.

Das elastische Material kann als Schlauch ausgebildet sein. In diesem Falle umhüllt es den Träger, eng an dessen Spiralwindungen anliegend, als Einheit flüssigkeitsdicht.The elastic material can be used as a hose be trained. In this case it envelops the Carrier, close to the spiral turns, as Liquid-tight 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. Auch bei diesem Stent sind die Spiralwindungen der Träger durch das Schlauchmaterial überbrückt. Im Gegensatz zu dem ersten Vorschlag ist das schlauchförmige Material aber nicht armiert in dem Abschnitt zwischen beiden Trägern. Dieser Stent kommt vorzugsweise dort zum Einsatz, wo die zu überbrückende Strecke relativ kurz ist.According to the second proposal, the stent consists of a hose made of liquid impermeable Material, in the two ends of each spiral-shaped carrier of high deformability and Stability is used, which is tight from the hose is wrapped tightly. Also with this stent the spiral turns of the carrier through the Hose material bridged. Contrary to that The first proposal is the tubular material but not armored in the section between the two  Carriers. This stent is preferably used there Use where the distance to be bridged is relative is short.

Der bzw. die Träger bestehen vorteilhafterweise aus einem körperverträglichen Metall. Alternativ ist aber auch die Verwendung eines körperverträglichen Kunststoffs möglich.The carrier or carriers advantageously consist of a body-compatible metal. Alternative is but also the use of a body-compatible Plastic possible.

Als elastisches Material für die Überbrückungen bzw. für den Schlauch eignet sich jedes einschlägige Material. Vorteilhaft ist die Verwendung von Latex.As an elastic material for the bridges or Any relevant one is suitable for the hose Material. The use of latex is advantageous.

Die Erfindung wird kurz anhand zweier Ausführungsbeispiele gemäß der Zeichnungen näher erläutert.The invention is briefly based on two Exemplary embodiments according to the drawings explained.

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. Die Formfestigkeit dieser langen Spirale gewährleistet es, daß das Lumen eines mit dem Stent 1 zu versehenden Gefäßes offengehalten wird.The stent 1 according to FIG. 1 has a spiral carrier 3 . The dimensional stability of this long spiral ensures that the lumen of a vessel to be provided with the stent 1 is kept open.

Der Träger 3 ist hier umhüllt von einem elastischen Schlauch, der aus einem flüssigkeitsundurchlässigen Material besteht. Der Schlauch liegt eng an dem spiralförmigen Träger 3 an.The carrier 3 is encased here by an elastic hose, which consists of a liquid-impermeable material. The hose lies closely against the spiral carrier 3 .

Der Stent 1′ gemäß Fig. 2 besteht aus einem Schlauch 2′ aus flüssigkeitsdichtem Material. In seine beiden Enden sind spiralförmige Träger 3′, 3′′ gesetzt. Die Spiralwindungen der Träger sind von dem Material des Schauches 2′ eng umhüllt.The stent 1 'shown in FIG. 2 consists of a tube 2 ' made of liquid-tight material. In its two ends spiral carriers 3 ', 3 ''are set. The spiral turns of the carrier are closely wrapped by the material of the hose 2 '.

Nach der Implantation des Stents in das zu behandelnde Gefäß tritt sofort eine Abdichtung beispielsweise einer Gefäßwandaussackung ein. Die sofort eintretende Abdichtung ist insbesondere bei der Behandlung von Fisteln erwünscht und notwendig.After implanting the stent into the treating vessel immediately seals for example, a vessel wall sack. The Immediate sealing is particularly important for the treatment of fistulas desired and necessary.
