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.
Claims (9)
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.
9. Spirale nach Anspruch 1-8, dadurch gekennzeichnet, daß für die Herstellung des Schnittmusters ein computergesteuertes Laser-Schneidverfahren
eingesetzt wird.
