摘要:
A multiple catheter system including an imaging scope having an elongated body having a first length and a first outer diameter. The elongated body including a first passage extending along the first length. A flexible distal tip portion is coupled to the elongated body. The flexible distal tip portion includes an imaging sensor and a light source. A proximal connector is coupled to the elongated body opposite the flexible distal tip portion. The proximal connector has a second outer diameter not greater than the first outer diameter. A first catheter includes a flexible distal tip portion and a first lateral extension disposed at the flexible distal tip portion. The first lateral extension includes a second passage having an inner diameter greater than the first outer diameter and the second outer diameter, wherein the imaging scope is movably positionable within the second passage.

Ein System 1 besteht aus einem Aspirationskatheter 2, der mittels eines Führungsdrahts 3 zu einer thrombotischen Stelle in einem Blutgefäß geführt wird. Innerhalb des Aspirationskatheters 2 befindet sich ein zusammengefalteter Infusionsballon 4, der einen Innenraum / Innenvolumen 40 aufweist, das durch eine Wand 41 begrenzt ist, und einen Zufuhrkatheter 42 aufweist. Der Zufuhrkatheter 42 ist für die Zufuhr saliner Lösung (Salzlösung) zum Spülen oder eines Thromben lösenden Medikaments in den Innenraum 40 bestimmt. Der Ballon weist eine Vielzahl von Öffnungen mit einem Durchmesser zwischen 10 µm und 100 µm auf, um eine atraumatische Applikation der Flüssigkeit zu ermöglichen.
摘要:
A catheter design and method is provided for the aspiration of thrombus, clot, atherosclerotic emboli in the vascular bed. The aspiration catheter includes an aspiration lumen, a guidewire lumen having an exchange port, and a recess in the aspiration unit. The aspiration catheter lumen is divided into two sections: (i) proximal, and (ii) distal. The distal section has a distal opening.
