Description

Implantationsvorrichtung für selbst-expandierende Stents Implantation device for self-expanding stents

Beschreibungdescription

Die Erfindung betrifft eine Implantationsvorrichtung für selbst-expandierende Stents gemäß Anspruch 1.The invention relates to an implantation device for self-expanding stents according to claim 1.

Aus dem Stand der Technik sind unterschiedliche Ausgestal- tungsformen von Stents bekannt. Diese bilden eine Gefäßprothese, welche aus körperverträglichem Material besteht. Stents werden im allgemeinen dazu verwendet, Hohlgefäße wie zum Beispiel Blutgefäße oder Körperöffnungen aufzuweiten und in einem aufgeweiteten Zustand zu halten. Zu diesem Zwecke wird der Stent normalerweise in einem nicht-expandierten Zustand im Körper des Patienten in ein verengtes Hohlgefäß positioniert und nachfolgend aufgeweitet. Üblicherweise besteht der Stentkörper aus einer Stegstruktur, wobei die Stegstruktur mehrere zueinander benachbarte, jeweils durch Stege begrenzte Zellen aufweist. Beim Expandieren werden die einzelnen Stegbereiche des Stents verformt, so daß dieser dauerhaft in der expandierten Form verbleibt.Different forms of stents are known from the prior art. These form a vascular prosthesis, which consists of body-compatible material. Stents are generally used to expand hollow vessels such as blood vessels or body openings and to keep them in an expanded state. For this purpose, the stent is normally positioned in a narrowed hollow vessel in the patient's body in an unexpanded state and subsequently expanded. The stent body usually consists of a web structure, the web structure having a plurality of adjacent cells, each delimited by webs. When expanding, the individual web areas of the stent are deformed so that it remains permanently in the expanded form.

Zum Aufweiten des Stents gibt es Konstruktionen, bei denen der Stent zuvor auf einen aufweitbaren Ballonkatheter aufgebracht wird und am Ort der Implantation durch Aufweiten des Ballons in seine Implantationsstellung in der Körperöffnung überführt wird. Eine Alternative sind selbst-expandierende Stents, die ohne die Notwendigkeit eines aufweitbaren Ballonkatheters implantiert werden können. Diese Stents sind aufgrund ihrer Konstruktion und ihres Materials dazu in der Lage, sich am Ort der Implantation von alleine aufzuweiten. Hierfür sind besondere Implantationsvorrichtungen erforderlich.There are designs for expanding the stent in which the stent is previously applied to an expandable balloon catheter and is transferred to its implantation position in the body opening by expanding the balloon at the site of the implantation. An alternative is self-expanding stents that can be implanted without the need for an expandable balloon catheter. Due to their design and material, these stents are able to expand on their own at the site of implantation. Special implantation devices are required for this.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Implantationsvorrichtung für selbst-expandierende Stents zu schaffen, die einfach aufgebaut und leicht zu bedienen ist.It is therefore an object of the present invention to provide an implantation device for self-expanding stents which is simple in construction and easy to use.

Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruches 1.This object is achieved by the features of claim 1.

Durch das Vorsehen eines Abdeckrohres ist es möglich, den auf einem Katheter aufgebrachten Stent von der nicht-expandierten, das Einsetzen in die Körperöffnung möglich machenden Stellung einfach durch Zurückziehen des Abdeckrohres in die expandierte Stellung zu überführen, da beim Zurückziehen der Abdeckvorrichtung der Stent aufgrund seiner die Selbst-Expansion möglich machenden Expansionskräfte ohne das Aufbringen weiterer Kräfte seine Implantationsstellung in der Körperöffnung einnimmt.By providing a cover tube, it is possible to transfer the stent applied to a catheter from the non-expanded position, which makes it possible to insert it into the body opening, simply by pulling back the cover tube into the expanded position, since when the cover device is withdrawn, the stent due to its the expansion forces which make self-expansion possible assume its implantation position in the body opening without the application of further forces.

Die Unteransprüche haben vorteilhafte Weiterbildungen der Erfindung zum Inhalt.The dependent claims contain advantageous developments of the invention.

Durch das Vorsehen eines Betätigungshebels und eines mit diesem in Wirkverbindung stehenden Seilzuges, der am Abdeckrohr angebracht ist, wird eine Übersetzung des Abzugsweges und somit eine Reduktion der aufzubringenden Kraft möglich gemacht. Der Seilzug wird hierzu am Hebel befestigt und durch eine Kipp- bzw. Schwenkbewegung des Betätigungshebels wird der Seilzug bzw. das Seil und das an diesem befestigte Abdeckrohr zurückgezogen. Durch die Hebellänge kann das Übersetzungsverhältnis, die Kraft und der zurückzulegende Weg variiert werden. Ferner wirα durch die Kippbewegung bzw. die Schwenkbewegung des Betätigungshebels ein kontrollierter Abzug des Abdeckrohres möglich gemacht.By providing an actuating lever and a cable pull that is operatively connected to it and is attached to the cover tube, a translation of the trigger path and thus a reduction in the force to be applied is made possible. For this purpose, the cable is attached to the lever and the cable or the cable and the cover tube attached to it are retracted by a tilting or swiveling movement of the actuating lever. The gear ratio, the force and the distance to be traveled can vary due to the lever length become. Furthermore, a controlled withdrawal of the cover tube is made possible by the tilting movement or the pivoting movement of the actuating lever.

Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus nachfolgender Beschreibung eines Ausfuhrungs- beispiels anhand der Zeichnung.Further details, features and advantages of the invention result from the following description of an exemplary embodiment with reference to the drawing.

Die einzige Figur der Zeichnung zeigt eine schematisch vereinfachte Darstellung einer erfmdungsgemaßen Implantiervorrichtung.The only figure in the drawing shows a schematically simplified illustration of an implantation device according to the invention.

Die in der Zeichnung dargestellte Implantiervorrichtung 1 für einen selbst-expandierenden Stent 2 ist m einem Zustand dargestellt, m dem der Stent 2 auf einem Katheter 3 plaziert ist. über dem Stent ist ein Abdeckrohr 4 angeordnet, das den Stent über seine gesamte Lange hm umgibt und somit auch den Teil des Katheters 3 umgibt, auf dem der Stent 2 angeordnet ist. Die Figur verdeutlicht, daß diese Position nahe der Katheterspitze 9 liegt.The implantation device 1 for a self-expanding stent 2 shown in the drawing is shown in a state in which the stent 2 is placed on a catheter 3. A cover tube 4 is arranged above the stent, which surrounds the stent over its entire length hm and thus also surrounds the part of the catheter 3 on which the stent 2 is arranged. The figure shows that this position is close to the catheter tip 9.

Die Figur verdeutlicht ferner das Vorsehen einer Betatigungs- einrichtung 5, die zum Zurückziehen des Abdeckrohres 4 entlang der durch den Pfeil A symbolisierten Katheterachse m Wirkverbindung steht.The figure also illustrates the provision of an actuating device 5 which is operatively connected to retract the cover tube 4 along the catheter axis m symbolized by the arrow A.

Bei der dargestellten besonders bevorzugten Ausfuhrungsform weist die Betatigungsemπchtung 5 einen langgestreckten Betätigungshebel 6 auf. Der Betätigungshebel 6 ist an einem Lagerbereich 10 des Katheters 3 mit Hilfe eines Schwenklagers 11 kipp- bzw. schwenkbar angebracht. Zwischen dem Schwenklager 11 und einem Handgriffteil 12 des Betätigungshebels 6 ist ein Befestigungspunkt 13 vorgesehen, an dem ein Ende 14 eines Seilzuges 7 befestigt ist. Der Befestigungspunkt 13 kann beispielsweise ein Stift sein, der m das beispielsweise schlaufenartig ausgebildete Ende 14 des Seilzuges 7 eingreift. Vom Befestigungspunkt 13 aus verlauft das Seil 7 m ein Fuhrungs- rohr 9, das auf einem außerhalb des Korpers des Patienten liegenden Teil des Katheters 3 angeordnet ist. Innerhalb dieses Fuhrungsrohres 9 verlauft der Seilzug 7 zu einem Anschlußteil 8, das ebenfalls stets auf einem Bereich des Katheters 3 angebracht ist, der beim Implantationsvorgang außerhalb des Korpers liegt. Das Anschlußteil 8 kann beispielsweise ein Ring oder eine Hülse sein, an dem das freie Ende des Seilzuges 7 auf geeignete Art und Weise befestigt ist.In the particularly preferred embodiment shown, the actuating device 5 has an elongated actuating lever 6. The actuating lever 6 is attached to a bearing area 10 of the catheter 3 by means of a pivot bearing 11 such that it can be pivoted or pivoted. An attachment point 13 is provided between the pivot bearing 11 and a handle part 12 of the actuating lever 6, to which one end 14 of a cable 7 is attached. The fastening point 13 can be, for example, a pin which engages the end 14 of the cable 7, which is designed in the manner of a loop, for example. from Fastening point 13 extends from the rope 7 m to a guide tube 9 which is arranged on a part of the catheter 3 lying outside the body of the patient. Within this guide tube 9, the cable 7 runs to a connecting part 8, which is also always attached to an area of the catheter 3 that lies outside the body during the implantation process. The connecting part 8 can be, for example, a ring or a sleeve, on which the free end of the cable 7 is fastened in a suitable manner.

Das den Stent umgebende Abdeckrohr 4 wiederum verlauft bis zum Anschlußteil 8, also bis zu einem Bereich des Katheters, der beim Implantationsvorgang außerhalb des Korpers liegt.The cover tube 4 surrounding the stent in turn extends up to the connection part 8, that is to say to an area of the catheter which lies outside the body during the implantation process.

Durch die genannte Konstruktion wird eine Verbindung zwischen dem Betätigungshebel 6 der Betatigungsemrichtung 5 und dem Abdeckrohr 4 geschaffen. Zum Implantieren wird zunächst der selbst-expandierende Stent 2 in der Nahe der Katheterspitze 9 auf den Katheter 3 aufgebracht und mit Hilfe des Abdeckrohres 4 in seiner Implantationsstellung gehalten, also einer Stellung, die das Einfuhren des Katheters mit dem darauf angebrachten Stent 2 m eine Korperoffnung, wie beispielsweise ein Blutgefäß, möglich macht. Ist die Stelle erreicht, wie beispielsweise eine Stenose m einem Blutgefäß, an der der Stent 2 implantiert werden soll, kann mittels des außerhalb des Korpers des Patienten verbleibenden Betätigungshebels 6 der Betatigungsemrichtung 5 das Abdeckrohr 4 entlang der Katheterachse A von der Katheterspitze 9 weg zurückgezogen werden. Hierfür muß der Betätigungshebel 6 um das Schwenklager 11 herum gekippt bzw. geschwenkt werden, wie dies durch die stπchliert dargestellten verschiedenen Stellungen 6 (Ri) , 6 (R2) , 6 (R3) und 6 (R4) m der Figur verdeutlicht ist. Der Betätigungshebel 6 wird also von seiner Ausgangsstellung 6 (R) , der er beim Implantationsvorgang bis zur Stenose verbleibt, m seine Endlage 6 (R4 ) ontinuierlich geschwenkt, und zieht somit ber den Seilzug 7 das Abdeckrohr 4 zurück. Wenn durch diesen Betätigungsvorgang der Stent 2 gänzlich vom Abdeckrohr 4 freigegeben wird, wird er aufgrund der Selbstexpansionskräfte in seine Implantationsstellung überführt, in der er beispielsweise in einem Blutgefäß eine Stenose dauerhaft aufweiten kann. The construction mentioned creates a connection between the actuating lever 6 of the actuating device 5 and the cover tube 4. For implantation, the self-expanding stent 2 is first applied to the catheter 3 in the vicinity of the catheter tip 9 and held in its implantation position with the aid of the cover tube 4, that is to say a position in which the insertion of the catheter with the stent attached thereon is a body opening such as a blood vessel. Once the position has been reached, such as a stenosis in a blood vessel on which the stent 2 is to be implanted, the cover tube 4 can be withdrawn away from the catheter tip 9 along the catheter axis A by means of the actuating lever 6 of the actuating device 5 remaining outside the patient's body . For this purpose, the actuating lever 6 must be tilted or pivoted around the pivot bearing 11, as is illustrated by the various positions 6 (Ri), 6 (R 2 ), 6 (R 3 ) and 6 (R 4 ) m shown in the figure in the figure is. The actuating lever 6 is thus pivoted continuously from its starting position 6 (R), which it remains during the implantation process up to the stenosis, m its end position 6 (R 4 ), and thus pulls the cover tube 4 back via the cable 7. If As a result of this actuation process, the stent 2 is released entirely from the cover tube 4, and due to the self-expansion forces, it is transferred into its implantation position, in which it can, for example, permanently widen a stenosis in a blood vessel.
