Abstract

The controllable balloon type catheter (1) has an opening, at the end furthest from the balloon, for a guide wire (4). This opening runs into an inner duct (3) which extends over the length of the catheter (1). A longitudinal slit (2) is formed in the catheter wall. This slit extends from any convenient position along the catheter to the outer end of the catheter. The slit (2) extends from the outer surface to the central duct (3). This slit facilitates the replacement of a guide wire when the catheter has been inserted into a blood vessel. USE - Catheters.

Description

Die Erfindung betrifft einen steuerbaren Ballonkatheter mit distal vom Ballon seitlich angeordneter Austrittsöff­ nung für den Führungsdraht.The invention relates to a controllable balloon catheter with an outlet opening arranged laterally distal to the balloon guide wire.

Ein steuerbarer Ballonkatheter der genannten Art hat den Nach­ teil, daß die Handhabung bei der Einführung des Katheters da­ durch erschwert wird, daß der Katheter und der Führungsdraht als zwei getrennte Teile erfaßt und in das Gefäß eingeführt werden müssen. Ferner besteht ein Nachteil darin, daß ein Aus­ tauschen des Führungsdrahtes bei im Gefäß verbleibendem Katheter nicht möglich ist, da das vordere Ende des Drahtes bei seiner Einführung sich nicht in die Austrittsöffnung einfädelt.A controllable balloon catheter of the type mentioned has the night part that handling when inserting the catheter there is complicated by the fact that the catheter and the guidewire detected as two separate parts and inserted into the vessel Need to become. Another disadvantage is that an off replace the guide wire with the catheter remaining in the vessel is not possible because the front end of the wire at its Introduction does not thread itself into the outlet opening.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu be­ seitigen und eine verbesserte Steuerungsmöglichkeit beider Teile auf ihrer gesamten gemeinsamen Länge zu gewährleisten.The invention has for its object to be these disadvantages sided and improved control of both parts to ensure along their entire common length.

Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß die Katheterwandung ab einer beliebigen Stelle bis hin zum außerhalb des Körpers liegenden Katheterende eine Unterbrechung in Form eines bis zur Kathetermittelachse hin reichenden Längsschlitzes aufweist.This object is achieved in that the Catheter wall from anywhere to outside an interruption in the shape of the end of the body a longitudinal slot extending to the central axis of the catheter having.

Die Erfindung ist nachstehend in zwei Ausführungsbeispielen an­ hand der Zeichnung erläutert und zwar zeigtThe invention is based on two exemplary embodiments hand of the drawing explained and shows

Fig. 4 eine Seitenansicht und Fig. 4 is a side view and

Fig. 5 einen Querschnitt durch die zweite Ausführungsform. Fig. 5 shows a cross section through the second embodiment.

Bei der in den Fig. 1 bis 3 dargestellten ersten Aus­ führungsform umschließt die Katheterwandung 1 den Führungs­ draht 4, der im inneren Führungskanal 3 des Katheters liegt.In the first to 3 shown in FIGS. 1 Off guide die encloses the catheter wall 1 the guide wire 4, which is the catheter in the inner guide channel 3.

Ab einer beliebigen Stelle des Katheters bis hin zum außer­ halb des Körpers liegenden Katheterende ist in der Katheter­ wandung 1 eine Unterbrechung in Form eines Längsschlitzes 2 vorgesehen, der bis zur Kathetermittelachse hin reicht.From any point on the catheter to the end of the catheter lying outside the body, an interruption in the form of a longitudinal slot 2 is provided in the catheter wall 1 , which extends to the central axis of the catheter.

Bei der in den Fig. 4 und 5 dargestellten zweiten Aus­ führungsform hat der Längsschlitz 2 eine sehr große Schlitz­ breite mit einem Öffnungswinkel von 180°.In the second embodiment shown in FIGS. 4 and 5, the longitudinal slot 2 has a very large slot width with an opening angle of 180 °.

Der beschriebene Längsschlitz gestattet einen problemlosen und raschen Austausch des Führungsdrahtes, der auf der ge­ samten Länge des Katheters durch den mittleren Führungskanal 3 gehalten und geführt wird.The described longitudinal slot allows a quick and easy exchange of the guide wire, which is held and guided over the entire length of the catheter through the central guide channel 3 .
