Radial aufweitbarer Stent zur Implantierung innerhalb eines KörperqefäßesRadially expandable stent for implantation inside a body vessel
Die Erfindung betrifft einen radial aufweitbaren Stent zur Implantierung innerhalb eines Körpergefäßes in Form eines hohlzylindrischen Elementes.The invention relates to a radially expandable stent for implantation inside a body vessel in the form of a hollow cylindrical element.
Stents werden in der Gefäßchirurgie zum Offenhalten eines Gefäßes, insbesondere nach einer Gefäßdilatation eingesetzt. Der Stent soll außerdem die Gefahr einer erneuten Okklusion verringern. Stents sind aus unterschiedlichen Materialien bekannt. Vielfach eingesetzt werden metallische, hohlzylindrische Gebilde, die entweder durch einen Ballonkatheter in den Gefäßen aufgespreizt werden oder die sich eigenständig radial aufweiten. Die heutzutage eingesetzten metallischen Stents bestehen in der Regel aus Edelstahl oder Edelstahllegierungen. Tantalum oder Nickel-Titan aber auch aus Titan, Aluminium, aus Edelmetallen wie Gold, Platin oder Silber. Neben der guten Körperverträglichkeit sollten die Stents nach der Implantierung auf einem Röntgenbild sichtbar sein, um ihre Lage kontrollieren zu können. Stents aus Edelstahl reflektieren jedoch Röntgenstrahlung nur schwach, so daß sie in einem Röntgenbild nur sehr schemenhaft zu erkennen sind. Andere Metalle wie Tantalum oder Edelmetalle reflektierenStents are used in vascular surgery to keep a vessel open, especially after a vessel dilation. The stent is also intended to reduce the risk of renewed occlusion. Stents are made of various materials. Metal, hollow-cylindrical structures are often used, which are either spread open in the vessels by a balloon catheter or which expand radially on their own. The metal stents used today are usually made of stainless steel or stainless steel alloys. Tantalum or nickel-titanium, but also titanium, aluminum, and precious metals such as gold, platinum or silver. In addition to being well tolerated by the body, the stents should be visible on an X-ray after implantation in order to be able to check their position. However, stents made of stainless steel only reflect X-rays weakly, so that they can only be seen very vaguely in an X-ray. Other metals such as tantalum or precious metals reflect
G 8781 DE - 2 -G 8781 EN - 2 -
Röntgenstrahlung sehr gut, wodurch die Stents aus diesen Materialien zwar im Röntgenbild gut sichtbar sind, jedoch dahinterliegende Körperregionen verdecken.X-rays are very good, which means that stents made of these materials are clearly visible in X-ray images, but cover up areas of the body behind them.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Stent bereitzustellen, dessen Lage nach der Implantierung in ein Körpergefäß auf einem Röntgenbild eindeutig lokalisierbar ist, ohne dabei die Sichtbarkeit des umliegenden Körpergewebes zu sehr zu beeinträchtigen.The present invention is based on the object of providing a stent whose position can be clearly localized on an X-ray image after implantation in a body vessel, without impairing the visibility of the surrounding body tissue too much.
Die Aufgabe wird mit einem Stent der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß er im wesentlichen aus einem Röntgenstrahlung nicht oder nur schwach reflektierenden Material gefertigt ist, jedoch mindestens einen Abschnitt mit einem Röntgenstrahlung gut reflektierenden Material aufweist. Der Stent ist somit gewissermaßen mit Markierungen versehen, die im Röntgenbild sichtbar sind, ohne daß dadurch hinter dem Stent liegende Körperregionen großflächig überdeckt würden. Dabei kann der mindestens eine Abschnitt mit einem Röntgenstrahlung gut reflektierenden Material aus einem Edelmetall oder einer Edelmetalllegierung, insbesondere aus Platin bestehen oder eine Beschichtung aus diesen Materialien aufweisen. Die die Röntgenstrahlung schwach reflektierenden Anteile des Stents können beispielsweise aus Edelstahl, Titan oder Nitinol gefertigt sein.The object is achieved according to the invention with a stent of the type mentioned at the beginning in that it is essentially made of a material that does not reflect X-rays or only reflects them weakly, but has at least one section with a material that reflects X-rays well. The stent is thus provided with markings that are visible in the X-ray image without covering large areas of the body regions behind the stent. The at least one section with a material that reflects X-rays well can consist of a precious metal or a precious metal alloy, in particular platinum, or can have a coating made of these materials. The parts of the stent that reflect X-rays weakly can be made of stainless steel, titanium or nitinol, for example.
Stents können beispielsweise durch Laserschneiden aus Röhrchen hergestellt werden. Bei einer solchen Fertigungstechnik kann der Stent aus mindestens einem hohlzylindrischen Abschnitt aus einem Röntgenstrahlung gut reflektierenden Material, der mit einem oder mehreren hohlzylindrischen Abschnitten aus einem Röntgenstrahlung schwach reflektierenden Material verbunden ist, gefertigt sein. Dabei können die hohlzylindrischen Abschnitte miteinander verschweißt sein.Stents can be made from tubes, for example, by laser cutting. With such a manufacturing technique, the stent can be made from at least one hollow cylindrical section made from a material that reflects X-rays well, which is connected to one or more hollow cylindrical sections made from a material that reflects X-rays poorly. The hollow cylindrical sections can be welded together.

Nach einer alternativen Fertigungstechnik kann der erfindungsgemäße Stent durch Laserschneiden, Stanzen oder Ätzen aus einem Blech, das aus parallelen Streifen aus Röntgenstrahlung gut und aus Röntgenstrahlung schwach reflektierenden Materialien besteht, gefertigt sein. Der so entstehende Rohling wird anschließend zusammengerollt und verschweißt. Die Lage des mindestens einen Abschnittes mit einem Röntgenstrahlung gut reflektierenden Material ist beliebig wählbar. So kann der Stent beispielsweise einen in seinem in axialer Richtung mittleren Bereich liegenden Abschnitt mit einem Röntgenstrahlung gut reflektierenden Material und/oder zwei, jeweils an seinen Enden angeordnete Abschnitte mit einem Röntgenstrahlung gut reflektierenden Material aufweisen.According to an alternative manufacturing technique, the stent according to the invention can be manufactured by laser cutting, punching or etching from a sheet of metal consisting of parallel strips of materials that reflect X-rays well and materials that reflect X-rays weakly. The blank thus created is then rolled up and welded. The position of the at least one section with a material that reflects X-rays well can be chosen as desired. For example, the stent can have a section in its central area in the axial direction with a material that reflects X-rays well and/or two sections with a material that reflects X-rays well, each arranged at its ends.
