Implantate, beispielsweise Stents, weisen heutzutage immer öfter sogenannte funktionelle Stellen auf, an denen das Implantat im Vergleich zum Rest ein anderes Material, eine andere Struktur, einen anderen Durchmesser oder eine andere Festigkeit aufweist. Des weiteren können im Bereich der funktionellen Stelle Seitenarme und/oder Kunststoffmaterialien zur Abdeckung von Aneurysmen und dergleichen angeordnet sein oder der Stent mit einer chemischen Substant, beispielsweise einem Wirkstoff oder einer Ätzenden Substanz.implants, for example stents, have so-called functional features more and more often these days Places where the implant is different from the rest Material, a different structure, a different diameter or one has different strength. Furthermore, in the field of functional Place side arms and / or plastic materials to cover Aneurysms and the like can be arranged or the stent with a chemical Substant, for example an active ingredient or an etchant Substance.

Derzeit ist es für einen Operateur nur möglich, anhand der Anfangs- und Endmarkierung die funktionelle Stelle in dem gewünschten Bereich des menschlichen oder tierischen Körpers anzuordnen.Currently is it for an operator only possible based on the start and end markings the functional position in the desired one Arrange area of the human or animal body.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, ein Set zur Verfügung zu stellen, mit dem man die funktionelle Stelle exakt in dem gewünschten Bereich des menschlichen und/oder tierischen Körpers anordnen kann.The The present invention is therefore based on the object of a set to disposal with which you can find the functional position exactly in the desired Can arrange the area of the human and / or animal body.

Gelöst wird die Aufgabe durch ein Set gemäß Anspruch 1. Bevorzugte Ausführungsformen des Sets sind in den Unteransprüchen 2 bis 15 beansprucht.Is solved the task through a set according to claim 1. Preferred embodiments of the Sets are in the subclaims 2 to 15 claims.

Vorzugsweise sind mehrere Markierungen im Bereich der funktionellen Stelle angeordnet, die beispielsweise deren Anfang und Ende markieren.According to the invention the catheter and in the area of the functional site or for identification arranged at least one marking of the tool. Preferably several markings are arranged in the area of the functional site, which, for example, mark their beginning and end.

An einer funktionellen Stellen im Sinne der Erfindung weist das Implantat im Vergleich zum Rest ein anderes Material, eine andere Struktur, einen anderen Durchmesser oder eine andere Festigkeit aufweist. Des weiteren können im Bereich der funktionellen Stelle Seitenarme und/oder Kunststoffmaterialien zur Abdeckung von Aneurysmen und dergleichen angeordnet sein oder das Implantat mit einer chemischen Substant, beispielsweise einem Wirkstoff oder einer Ätzenden Substanz versehen sein.On the implant has functional locations within the meaning of the invention a different material, structure, compared to the rest, has a different diameter or strength. Furthermore, you can in the area of the functional site side arms and / or plastic materials be arranged to cover aneurysms and the like or the implant with a chemical substance, for example one Active ingredient or an caustic Substance.

Es war für den Fachmann überaus erstaunlich und nicht zu erwarten, dass es mit dem erfindungsgemäßen Set gelingt, die funktionelle Stelle und/oder das Werkzeug punktgenau in einem menschlichen Körper zu platzieren. Durch die Kennzeichnung der funktionellen Stelle kann der Operateur diese sehr einfach in dem menschlichen oder tierischen Körper entsprechend anordnen und muss nicht aufgrund der Anfangs- und Endmarkierung auf die Lage der funktionellen Stelle schließen.It was for the specialist extremely amazing and not to be expected with the set according to the invention succeeds in pinpointing the functional location and / or the tool in a human body to place. By marking the functional position the surgeon can do this very easily in human or animal body arrange accordingly and does not have to because of the start and end markings deduce the position of the functional site.

In einer bevorzugten Ausführungsform der vorliegenden Erfindung ist auf dem Katheter mindestens eine zusätzliche Markierung angeordnet, mit der der Anfang und/oder das Ende des Implantates bzw. des Werkzeuges gekennzeichnet ist. Diese bevorzugte Ausführungsform des erfindungsgmäßen Sets hat den Vorteil, dass durch das jeweilige bildgebende Verfahren für den Operateur nicht nur der Bereich der funktionellen Stelle, sondern auch der Anfang bzw. das Ende des Implantates bzw. des Werkzeuges erkennbar ist, so dass eine noch bessere Positionierung des Implantates möglich ist.In a preferred embodiment of the present invention is at least one on the catheter additional Marking arranged with the beginning and / or the end of the Implant or the tool is marked.

The markings are particularly preferred the functional location and the beginning and end of the implant attached to the inner tube of the catheter so that it Do not widen the balloon.

Die Markierungen können aus jedem beliebigen Material gefertigt sein. Vorzugsweise sind die Markierungen jedoch aus einem Material gefertigt, das bei dem jeweiligen Visualisierungsverfahren für den Operateur gut sichtbar ist. Wird beispielsweise Röntgenstrahlung zur Visualisierung des Implantates eingesetzt, so ist ein Material mit einer hohen Röntgendichte bevorzugt. Ein derartiges Material ist beispielsweise Gold oder Platin oder deren Legierungen.The Marks can be made of any material. Are preferred the markings, however, are made of a material that the the respective visualization process is clearly visible to the surgeon is. For example, X-rays a material is used to visualize the implant a high x-ray density prefers. Such a material is, for example, gold or Platinum or their alloys.

Ganz besonders bevorzugt ist das Material darüber hinaus biokompatibel.All the material is also particularly preferably biocompatible.

Vorzugsweise sind die Markierungen der funktionellen Stelle und des Anfangs bzw. des Endes des Implantates unterschiedlich. Besonders bevorzugt weisen sie ein unterschiedliches Visualisierungsverhalten und/oder eine unterschiedliche Form auf, so dass der Chirurg eindeutig unterscheiden kann, ob es sich um eine Anfangs- bzw. Endmarkierung oder eine Markierung der funktionellen Stelle handelt.Preferably are the markings of the functional location and the beginning or of the end of the implant different. Point particularly preferably they have a different visualization behavior and / or a different shape so that the surgeon can clearly differentiate whether it is a start or end mark or a mark the functional body.
