Abstract
Description
Die Erfin'ung betrifft einen Ballonkatheter gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a balloon catheter according to the preamble of claim 1.
Die Erfindung geht aus von einem Ballonkatheter wie er in dem DE-Patent (Patentanmeldung P 30 18 608.4-35) beschrieben ist.The invention is based on a balloon catheter like the one in the DE patent (Patent application P 30 18 608.4-35) is described.
Ein derartiger Katheter weist gegenüber den Kathetern, die beispielsweise schirmartige Verschlußkörper aufweisen (FR-A 23 28 483 GB-PS 15 09 023) und Ballonkathetern (FR-A 2382673) erhebliche Vorteile auf, weil es mit dem Positionsballon möglich ist den Verschlußballon exakt zu positionieren.Such a catheter has compared to the catheters, for example Have umbrella-like closure bodies (FR-A 23 28 483 GB-PS 15 09 023) and balloon catheters (FR-A 2382673) has considerable advantages because it is possible with the position balloon the occlusion balloon has to be positioned exactly.
Das Ablösen des Verschlußballons erfolgt beim Hauptpatent durch eine Relativverschiebung über den entleerten Positionsballon, d.h. der Positionsballon wird mit dem Katheter zusammen durch die Öffnung im Verschlußballon gezogen. Die Öffnung schließt sich anschließend von allein bzw. setzt sich zu.The release of the sealing balloon takes place in the main patent by a Relative displacement over the deflated position balloon, i.e. the position balloon is pulled together with the catheter through the opening in the occlusion balloon. the The opening then closes by itself or becomes blocked.
Ausgehend von dem im Hauptpatent beschriebenen Katheter, liegt der Erfindung die Aufgabe zugrunde den Ablösungsvorgang des Verscblußballons vom Katheter zu erleichtern und die Herstellung zu vereinfachen.Based on the catheter described in the main patent, the The invention is based on the object of the process of detaching the balloon from the catheter to facilitate and to simplify manufacture.
Gelöst wird diese Aufgabe erfindungsgemäß durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale.This object is achieved according to the invention by means of the characteristics of claim 1 specified features.
Bebùnders vorteilhaft ist die Ausgestaltung gemäß dem Anspruch 2.The embodiment according to claim 2 is particularly advantageous.
Durch die erfindungsgemäße Lösung entfällt das Hindurchziehen des Positionsballons durch die Öffnung des Verschlußballons. Vielmehr werden beide Ballons oder Ballonteile - gemäß Anspruch 2 - vom Katheter abgelöst, wobei der Positionsballon so gestaltet sein kann, daß sein; Verbleiben im entleerten Zustand im Körper ohne nachteilige Auswirkungen auf den Blutstrom ist, oder der Positionsballon bei Lösung des Katheters zunächst von distal in die Katheteröffnung des Verschlußballons eingezogen wird und sich in dieser Stellung vom Katheter durch weiteren Zug desselben löst.The solution according to the invention eliminates the need to pull the Position balloons through the opening of the occlusion balloon. Rather, both become balloons or balloon parts - according to claim 2 - detached from the catheter, wherein the position balloon can be designed so that; Remaining in the emptied state in the body without adverse effects on blood flow, or the position balloon when released of the catheter is initially drawn into the catheter opening of the occlusion balloon from the distal side and in this position it detaches itself from the catheter by pulling it further.
Ein Zusetzen des Lumen - wie beim Hauptpatent - tritt daher nicht auf.A clogging of the lumen - as in the main patent - therefore does not occur on.
Durch die Ausgestaltung nach Anspruch 2, ist der Herstellungsvorgang für den Katheter wesentlich vereinfacht worden.Due to the configuration according to claim 2, the manufacturing process for the catheter has been significantly simplified.
Die Erfindung soll nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels erläutert werden, wobei der Katheter in Längsrichtung gezeigt ist.The invention is to be illustrated below with reference to one shown in the drawing Embodiment will be explained, the catheter shown in the longitudinal direction is.
Wie beim Hauptpatent weist der Katheter 1' drei Kanäle oder Lumen la' - c' auf. Am distalen Ende des Katheters ist - bei dem dargestellten Ausführungsbeispiel - ein sich über eine bestimmte axiale Länge des Katheters erstrekkender, das distale Ende des Katheters umgeben, der Ballon vorgesehen. Dieser wird durch einen eng am Katheter 1' anliegenden Ring in zwei Ballonabschnitte geteilt -wobei dies durch die Formgebung bereits vorgegeben ist -und zwar entsprechen diese dem Positionsballon 3' und dem Verschlußballon 5' des Hauptpatentes. Der aus den Ballonabschnitten 3' und 5' bestehende Ballon ist auf den Katheter aufgeschoben und mit diesem lösbar verbunden, und zwar kann dies z.B. durch einen chemisch oder thermisc> sich zeitabhängig auflösenden Kleber oder auch eine geeign e mechanische Verbindung geschehen. Das Ablösen oder A schieben vom Katheter erfolgt mit Hilfe einer scæenannten Schleuse 2'.As in the main patent, the catheter 1 'has three channels or lumens la '- c' on. At the distal end of the catheter is - in the illustrated embodiment - one that extends over a certain axial length of the catheter, the distal one Surrounding the end of the catheter, the balloon is provided. This is through a close on Catheter 1 'adjoining ring divided into two balloon sections - this being through the shape is already given - and this corresponds to the position balloon 3 'and the sealing balloon 5' of the main patent. The one from the balloon sections 3 ' and 5 'existing balloon is pushed onto the catheter and detachable with it tied together, This can be done, for example, by a chemical or thermal> Time-dependent dissolving adhesive or a suitable mechanical connection happen. The detachment or pushing of the catheter takes place with the help of a scæenanned Lock 2 '.
Der besch: Lebene Katheter wird über die Beinvene eingeführt, bis zum Herz vorgeschoben und über die Lungenschlagader durch den persistierenden Ductus arteriosus bis in die Körperschlagader gelegt, wie bei einer routinemäßigen Herzkatheteruntersuchung. Dann wird der Positionsballon 3' mit Gas oder flüssigem Kontrastmittel (durch den Kanal lc' und die Öffnung 4') aufgefüllt und mit dem Katheter bis zum Ansatz des persistierenden Ductus arteriosus zurückgezogen. Der Verschlußballon 5' liegt dann innerhalb der zu verschließenden Gefäßverbindung.The dam: Leben catheter is inserted through the leg vein until advanced to the heart and via the pulmonary artery through the persistent duct arteriosus is laid down into the artery, as in a routine cardiac catheter examination. Then the position balloon 3 'is filled with gas or liquid contrast medium (through the Channel lc 'and the opening 4') and filled with the catheter up to the approach of the persistent ductus arteriosus withdrawn. The occlusion balloon 5 'then lies within the vascular connection to be closed.
Es erfolgt dann wie beim Hauptpatent, die Füllung des Verschlußballons mit röntgendichtem, aushärtenden Silikon, wobei ebenfalls gleichzeitig eine Entlüftung vorgesehen ist.As with the main patent, the sealing balloon is then filled with radiopaque, hardening silicone, also with ventilation at the same time is provided.
Die jeweiligen Kanäle bzw. Öffnungen sind mit la', lb', 7' und 8' bezeichnet.The respective channels or openings are marked with la ', lb', 7 'and 8' designated.
Anschließend wird der Positionsballon entleert. Beim Abziehen bzw. Abschieben der Ballons 3', 5' vom Katheter mittels der Schleuse 2' wird der entleerte Positionsballon oder Ballonabschnitt mit der Katheterspitze in die Öffnung des mit ausgehärtetem Silikon gefüllten Verschlußballons 5' eingezogen, bis bei der Weiterbewegung des Katheters das Ablösen von der Spitze erfolgt.The position balloon is then deflated. When pulling or Pushing off the balloons 3 ', 5' from the catheter by means of the sluice 2 'is the deflated one Position balloon or balloon section with the catheter tip in the opening of the with Cured silicone-filled sealing balloons 5 'pulled in until moving on the catheter is detached from the tip.
Der Verschlußballon bleibt exakt positioniert und der persistierende Ductus arteriosus ist damit auf Dauer komplett verschlossen.The occlusive balloon remains exactly positioned and the persistent one The ductus arteriosus is thus completely closed in the long term.
