GEBRAUCHSMUSTERANMELDUNG Im Schneid verfahren herstellbarer Helixstent "
Stents (= Endoprothesen aus Metall) werden in Hohlorgane des menschlichen Körpers implantiert, um Engstellungen zu behandeln. Sie können als gewobenes, gestricktes, gelötetes oder geschweißtes Drahtgebilde hergestellt werden. Eine Möglichkeit, Stents herzustellen, besteht darin, in ein dünnes Metallrohr mit einem fokussierten Laserstrahl ein regelmäßiges Schlitzmuster zu schneiden, das sich gleichmäßig über dem gesamten Umfang wiederholt. Beim Auf dehnen des Rohres durch einen Ballonkatheter weiten sich die Schlitze gleichmäßig auf. Der Stent wird expandiert und legt sich der Wand des Hohlorgans, das geschient werden soll, an. Alternativ kann eine Nickel-Titan-Legierung ("Memory-Metall") verwendet werden. Durch eine Wärmebehandlung wird erreicht, daß das Metallrohr bei Erwärmung von Umgebungs- auf Körpertemperatur bei Verlassen des Einführungskatheters selbst expandiert.
Es sind bereits Stents bekannt, die in der beschriebenen Weise hergestellt werden: der Palmaz-Stent (Johnson u. Johnson Interventional Systems, Warren, NJ, USA), der Memotherm-Stent (Bard-Angiomed, Karlsruhe) und der Sinus-Stent (Optimed Medizinische Instrumente, Ettlingen). Allen drei Stenttypen ist jedoch gemeinsam, daß sie sich aufgrund ihrer axialen Steifigkeit nur bedingt gekrümmten Segmenten von Hohlorganen anpassen können. Dies gilt insbesondere für gekrümmte Blutgefäßabschnitte, aber auch beispielsweise für das Gallenwegssystem.
Der hier beschriebenen Erfindung liegt die Aufgabe zugrunde, einen Stent zu realisieren, der im computergesteuerten Laserschneidverfahren aus einem Metallrohr-Halbzeug hergestellt werden kann und eine im Vergleich zu den bekannten Stenttypen deutlich verbesserte axiale Krümmungsfähigkeit aufweist, die eine Anpassung an gekrümmte Hohlorgane erlaubt. Eine Lösung dieser Aufgabe wurde bereits in dem Gebrauchsmuster Nr. 29721310.5 (IPC: A6IF) beschrieben.
Zur speziellen Lösung dieser Aufgabe wird ein mit einem bestimmten Muster geschnittenes Metallrohr mit den im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmalen vorgeschlagen. Das Schnittmuster kann in Lasertechnik in das Rohr eingebracht werden.
Die Form des erfindungsgemäßen Schnittmusters des nicht expandierten Stents ist in Fig. 1 dargestellt.
Das Grundmuster besteht aus einer Helix (= Wendel; im medizinischen Sprachgebrauch meist „Spirale" genannt). Diese wird gebildet aus einer Aneinanderreihung schlitzförmig eingeschnittener Glieder (1), welche miteinander über einen Mittelsteg (2) in Verbindung stehen. Bei Ballonexpansion erhalten die Glieder (1) ein rautenförmiges Aussehen. Zur Verbesserung der Stabilität stehen die einzelnen Helix-Windungen über Querstege (3) miteinander in Verbindung. Die Querstege (3) sind dünner als die Stege (2) und die Glieder (1). Sie sind in regelmäßigen Abständen angeordnet (vorzugsweise an jedem dritten Glied (I)). Der Z-förmige Verlauf der Querstege (3) erlaubt eine Anpassung des Abstandes der benachbarten Helixwindungen zueinander. Bei Expansion des Stents in einem gekrümmten Hohlorgan lassen die Querstege im Bereich der großen Kurvatur durch Streckung einen größeren Abstand benachbarter Helixwindungen zu. Der Abschluß der Helix zu beiden Enden erfordert die Anbindung einiger mäanderförmiger Windungen (4), zur Gewährleistung der Überdeckung und eines gleichförmigen Abschlusses des Stents über dem gesamten Umfang. Die Mäander (4) sind über gerade verlaufende Querstege (5) an das jeweils benachbarte Glied (1) der Helix angebunden.

SCHUTZANSPRUCHE
1. Im Schneidverfahren aus einem Rohr herstellbare, implantierbare, tubuläre Endoprothese („Stent"), dadurch gekennzeichnet, daß das Grundmuster eine Helix darstellt, welche sich aus einer helixförmig gewundenen Kette miteinander verbundener Einzelglieder zusammensetzt.
2. Helixstent nach Anspruch 1, dadurch gekennzeichnet, daß die Einzelglieder im nicht-expandierten Zustand eine flach-ovale, axial orientierte Form mit einem axial verlaufenden Schlitz aufweisen, welche nach Expansion des Stents ein rautenförmiges Aussehen erlangen, und daß die Einzelglieder über einen Mittelsteg miteinander verbundenen sind.
3. Helixstent nach Anspruch 1 und 2, dadurch gekennzeichnet, daß benachbarte Helixwindungen über Querstege miteinander verbunden sind, derart, daß die Querstege direkt benachbarte Einzelglieder verbinden oder zum nächsten oder übernächsten Einzelglied verbinden.
4. Helixstent nach Anspruch 1-3, dadurch gekennzeichnet, daß die Querstege einen Z- oder S-förmigen Verlauf aufweisen.
5. Helixstent nach Anspruch 1-4, dadurch gekennzeichnet, daß sich zu beiden Enden der Helix ein aus mehreren mäanderförmigen Windungen bestehender Abschnitt anschließt, wobei die Windungen entsprechend der Steigung der Helix eine abnehmende axiale Breite aufweisen, so daß sich nahezu über dem gesamtem Umfang ein gleichmäßiger stirnseitiger Abschluß des Stents ergibt.
6. Helixstent nach Anspruch 1-5, dadurch gekennzeichnet, daß einige oder jede der mäanderförmigen Windungen über Quer Stege mit den Einzelgliedern der benachbarten Helixwindung verbunden sind.
h ·
7. Spirale nach Anspruch 1-6, dadurch gekennzeichnet, daß als Material eine Metalllegierung verwendet wird.
8. Spirale nach Anspruch 1-7, dadurch gekennzeichnet, daß als Material eine Memory-Metalllegierung (Nickel-Titan) verwendet wird.
