Description
- Hintergrund der Erfindung
- Die vorliegende Erfindung bezieht sich auf Stents. Allgemein ausgedrückt ist ein Stent ein Gerät, das innerhalb eines Körperhohlraums oder eines Innenraums platziert ist, um die Durchgängigkeit eines Hohlraums zu unterstützen und abzusichern. Die Durchgängigkeit bezieht sich auf einen unbehinderten und freien Zustand und ist in einem vaskularen System besonders wichtig. Das Gebiet der Angioplastie ist mit der Wiederherstellung von Blutgefäßen befasst, und Stents werden beispielsweise zum Offenhalten von Blutgefäßen oder zum Wiederanheften von innersten Klappen im Inneren von Gefäßen nach der Angioplastie verwendet. Noch allgemeiner können Stents allerdings im Inneren der Hohlräume eines jeden beliebigen physiologischen Kanals, einschließlich der Arterien, Adern, Gefäße, der Gallenwege, des Harntrakts, des Verdauungstrakts, der trachealen bronchialen Verästelungen, des genito-urinären Systems und des zerebralen Leitungssystems, verwendet werden. Stents können im Inneren der Körperhohlräume von Tieren und/oder Menschen benutzt werden.
- Stents sind im Allgemeinen rohrförmig in der Struktur und zwischen einer nicht expandierten Größe oder einem nicht expandierten Umfang beim Einsetzen und einer expandierten Implantationsgröße oder einem expandierten Implantationsumfang, die/der größer ist als die nicht expandierte Größe, radial expandierbar.
- Eine wichtige Eigenschaft eines Stents ist, dass er radial komprimierbar und expandierbar ist, sodass er ein Blutgefäß oder dergleichen leicht durchlaufen wird, wenn er zusammengelegt ist, und er wird bis zu seiner Implantationsgröße expandieren oder er kann bis zu seiner Implantationsgröße expandiert werden, nachdem die Implantationsstelle erreicht worden ist. Es ist außerdem erstrebenswert, dass ein Stent generell über seine Länge hin flexibel ist, sodass er leicht durch Biegungen und Krümmungen des vaskularen Systems oder dergleichen manövrierbar ist, um die Implantationsstelle zu erreichen, und dass der Stent der vaskularen Stelle entspricht, wenn er expandiert ist. Üblicherweise ist es auch wünschenswert, dass ein Stent in einem wesentlichen Umfang einen offenen Raum besitzt, um eine Endothelialisierung über seine Länge hinweg zu ermöglichen, zur Minimierung der Fremdkörperreaktion und um die Beeinträchtigung parallel laufender Blutgefäße und dergleichen zu minimieren.
- Es sind verschiedene Arten von Stents und verschiedenartige Ausführungen von Stents vorgestellt worden. Im Allgemeinen werden Stents klassifiziert als selbstexpandierend, das heißt, wenn sie selbst expandieren und als ballonexpandiert, das heißt, wenn sie durch einen Ballon expandiert werden, der im Inneren des Stents eingesetzt ist.
- Aus der Sicht der Materialien können Stents klassifiziert werden als hergestellt aus verschiedenartigen Metallen, zum Beispiel aus rostfreiem Stahl, Nitinol, und als hergestellt aus verschiedenartigen Kunststoffen.
- Stents können aus rohrförmigen Stoffstrukturen hergestellt werden, aus denen das gewünschte Design ausgeschnitten oder geätzt werden kann. Außerdem können Stents aus Draht hergestellt werden. Beide Arten sind weithin bekannt.
- Diese Erfindung bezieht sich auf alle der oben erörterten Arten von Stents.
- WO 98/30173 legt einen selbst-expandierenden vaskularen Stent mit niedrigem Querschnitt offen, der eine spiralförmige Windung besitzt, die eine im Allgemeinen rohrförmige Gestalt bildet. Brücken verbinden die besagten Windungen untereinander. Die spiralförmigen Windungen sind von zyklischer Struktur, die eine konstante Wellenlänge und eine konstante Breite aufweist.
-
US 5,810,872 legt einen flexiblen Stent offen, der ein diagonal ausgerichtetes Band aufweist, das spiralförmig zu einer zylindrischen Form gewunden ist. Das Band besitzt eine regelmäßige wellenförmig verlaufende Gestalt und ist durch gerade Verbindungsstreben verbunden. - Das technische Problem der Erfindung liegt darin, einen Stent vorzusehen, der ein spiralförmig gewundenes Bandelement besitzt, das eine ungleichmäßige Kraftverteilung liefert, ohne die Struktur des Stents zu schwächen.
- Das Problem ist gemäß Anspruch 1 gelöst.
- Die Erfindung liefert einen Stent, der eine spiralförmig gewundene schlangenartige oder wellenförmig verlaufende Struktur aufweist, einschließlich gebogener, das heißt gekrümmter, Verbindungselemente, die in der expandierten Form geschlossene flexible Zellen bildet. Im Verbund führen die flexiblen Zellen zu einem flexiblen, konformen Stent, der gleichmäßig expandiert und eine gute radiale Kraft, gute wie ein Gerüst wirkende Eigenschaften und gute Ermüdungseigenschaften liefert, wenn er expandiert wird.
- Stents, die das Design der Erfindung berücksichtigen, werden, entsprechend dem Stand der Technik, vorzugsweise aus Drahtwindungen hergestellt oder aus Rohren, zum Beispiel Metallrohren, die geätzt oder lasergeschnitten werden, um die gemäß der Erfindung gewünschte Konfiguration des Stents zu erhalten.
- Kurze Zusammenfassung der Erfindung
- Allgemein ausgedrückt, liefert die vorliegende Erfindung einen Stent, der zwei hauptsächliche Strukturelemente aufweist, wobei das erste ein der Länge nach zusammenhängendes spiralförmiges Element darstellt, das vorzugsweise beabstandete wellenförmig verlaufende Teile enthält, die zyklische Schlaufenendteile, das heißt eine schlangenförmige Konfiguration, bilden, wobei sich das spiralförmige Element im Wesentlichen über die Länge des Stentkörpers hin erstreckt, um eine zylindrische Stentkonfiguration zu erzeugen. Das zweite Element umfasst eine Vielzahl von gekrümmten, am meisten bevorzugt sinusförmigen, Verbindungsstücken, die sich zwischen den benachbarten wellenförmig verlaufenden Teilen erstrecken und zumindest einige von ihnen untereinander verbinden, und die vorzugsweise mit den Schlaufenendteilen des spiralförmigen Elements über seine Länge hin verbunden sind. Eine zweite parallele Spirale kann oder mehrere parallele Spiralen können ebenfalls verwendet werden, bevorzugt wird die einzelne Spirale, wie sie hier unten beschrieben wird.

- Während diese Erfindung in vielen verschiedenen Formen ausgeführt werden kann, werden hier spezielle bevorzugte Ausführungsformen der Erfindung im Detail beschrieben. Diese Beschreibung ist eine Veranschaulichung der Grundsätze der Erfindung, und es ist nicht beabsichtigt, die Erfindung auf die erläuterten besonderen Ausführungsformen zu beschränken.
- Ein Stent
10 eines ersten Beispiels ist in1 dargestellt. Der Stent10 ist aus einem diagonal ausgerichteten spiralförmigen Band11 gebildet, das spiralförmig in einer zylindrischen Form angeordnet ist. Das Band11 enthält wellenförmig verlaufende Teile12 über seine ganze durchgehende Länge, um eine schlangenförmige Konfiguration zu liefern. Wie in der Figur ersichtlich, beinhaltet jedes der wellenförmig verlaufenden Teile Schlaufenendteile13 . Jedes Schlaufenendteil13 ist mit einem benachbarten, der Länge nach beabstandeten Teil13 durch ein gekrümmtes Verbindungselement14 verbunden, das in dieser Ausführungsform zwei Krümmungen oder U-förmige Teile14a und14b enthält, um ein Verbindungsstück zu bilden, das die gewünschte sinusförmige Form aufweist. Wie aus1 ebenfalls ersichtlich ist, verbinden sich die Verbindungselemente14 in dieser Ausführungsform vorzugsweise mit den Endteilen13 an ihren äußersten Enden und erstrecken sich unmittelbar zwischen den in der Längsrichtung beabstandeten benachbarten Endteilen. Die Verbindungsstücke können an anderen Stellen als den äußersten Enden der Wellenformen befestigt sein. Außerdem sollte mit Bezug auf den Stent der1 erwähnt werden, dass die Wellenformen versetzt sind, wie es durch die Linien16 angezeigt ist. - In dieser Ausführungsform, wie in allen der offengelegten Ausführungsformen, wird der Stent vorzugsweise aus einem rohrförmigen Lagematerial durch Laserschnitt geformt. Jedoch kann ein Rohr auch geätzt werden. Es ist möglich, eine gewünschte Konfiguration aus flachem Folienmaterial zu formen, das dann in die gewünschte zylindrische Form gebogen wird. Dies ist ein in Fachkreisen bekanntes Verfahren.
- Wenn ein Stent, wie er zum Beispiel in
1 dargestellt wird, in einen Körperhohlraum, wie zum Beispiel eine Arterie, implantiert wird, wobei der Stent, während er in den Hohlraum an die gewünschte Stelle transportiert wird, einen anfänglichen Durchmesser D1, wie er in1a dargestellt wird, besitzt, kann der Stent während des Transports in einem gewundenen Hohlraum leicht gebogen und gekrümmt werden. Wie in1b dargestellt, wird der Stent danach bis zu einem zweiten Durchmesser D2 expandiert, der größer ist als der anfängliche Durchmesser D1, womit der Stent implantiert ist. - Wie in Fachkreisen bekannt ist, wird zur Implantation und Expansion des Stents vorzugsweise eine Transportkatheterbaugruppe verwendet, mit einem expandierbaren Element, wie zum Beispiel einem Ballon. Wenn die Katheterbaugruppe mit einem Ballon verwendet wird, um den Stent zu befördern, wird der Stent auf dem Ballon montiert und die Katheterbaugruppe bis zur Implantationsstelle geschoben. Danach wird der Ballon aufgeblasen, wobei er auf das Innere des Stents eine Kraft radial anwendet, und der Stent bis zu seinem erweiterten Durchmesser expandiert wird.
- Nunmehr bezugnehmend auf
2 , wird ein zweites Beispiel der Erfindung dargestellt, das im Hinblick auf die meisten Gesichtspunkte der in1 dargestellten Ausführungsform ähnlich ist, mit der Ausnahme, dass die sinusförmigen Verbindungselemente14 sich zwischen Endteilen13 erstrecken, die nicht nur der Länge nach benachbart sind, sondern aufwärts oder abwärts untereinander beabstandet sind. Außerdem ist die schlangenförmige Konfiguration versetzt. - Nunmehr bezugnehmend auf
3 , wird ein anderes Beispiel dargestellt, das ähnliche wellenförmige Strukturelemente11 aufweist, wie es unter Bezugnahme auf die1 und2 beschrieben wurde. In diesem Beispiel besitzen die Verbindungselemente14 jedoch eine unterschiedliche Konfiguration, in dem Sinne, dass die zwei U-förmigen Bogen14a und14b näher zusammenstehen, wobei die daraus resultierende Konfiguration genau genommen nicht "sinusförmig" sondern gekrümmt ist. - Andere gekrümmte Konfigurationen, zum Beispiel spiralförmige Konfigurationen, können ebenfalls für die Verbindungselemente verwendet werden.
- Nunmehr bezugnehmend auf das Beispiel der
4 , ist es ersichtlich, dass diese Ausführungsform der aus der1 ebenfalls einigermaßen ähnlich ist. In dieser Ausführungsform jedoch sind die Enden des Stents in Bezug auf die Längsachse des Stents40 eher rechteckig weggebogen als diagonal, wie in1 dargestellt, ausgerichtet. - Nunmehr bezugnehmend auf
5 , wird eine Ausführungsform eines Stents50 gemäß dieser Erfindung dargestellt. Wiederum sind die Basiselemente dieses Stents denen der vorhergehenden Ausführungsformen ähnlich, mit der Ausnahme, dass die spiralförmigen Elemente11 in der Anordnung nicht lediglich diagonal sondern auch gekrümmt sind. Dies wird unter Bezugnahme auf die Linien18 veranschaulicht. - Nunmehr bezugnehmend auf das in der
6 dargestellte Beispiel, ist es ersichtlich, dass die Wellenformen des spiralförmigen Elements11 phasengleich ausgerichtet werden können, wie es durch die Linien20 dargestellt wird. - Nunmehr bezugnehmend auf die
7 ,8 und9 wird in jeder Figur ein Fragment eines Stents10 dargestellt, einschließlich spiralförmiger Bänder11 . In den7 und9 sind die Bänder aus untereinander verbundenen rechteckigen Zellen zusammengesetzt und in8 bestehen die Zellen aus verbundenen schlangenförmigen oder diamantförmigen Zellen. In diesen Figuren besitzen die gekrümmten Verbindungselemente14 die bevorzugte sinusförmige Konfiguration. - Die oben dargestellten Beispiele und die Offenlegung sollen veranschaulichend und nicht abschließend sein. Diese Beispiele und die Beschreibung werden dem Fachmann auf diesem Gebiet viele Variationen und Alternativen nahe legen.
