BESCHREIBUNGDESCRIPTION

zweilumiger Fangkorbkatheterdouble-lumen basket catheter

Fangkorbkatheter sind in der Medizin, hier insbesondere in der Interventionellen Radiologie, für die Extraktion von Fremdkörpern oder Konkrementen aus Gefäßsystemen z. B. Blutgefäße, Gallengänge - weit verbreitet und allgemein eingeführt.Basket catheters are widely used and generally accepted in medicine, especially in interventional radiology, for the extraction of foreign bodies or concretions from vascular systems, e.g. blood vessels, bile ducts.

Begrenzt wird die Anwendungsweise dieser Katheter jedoch in schwierig zu sondierenden Gefäßen, weil bei der Extraktion immer das gesamte Kathetersystem aus dem Gefäß entfernt werden muß und deshalb häufig nur ein einmaliger Extraktionsversuch unternommen werden kann. However, the use of these catheters is limited in vessels that are difficult to probe because during extraction the entire catheter system always has to be removed from the vessel and therefore often only a single extraction attempt can be made.

Bei der jetzigen Erfindung kann jedoch über das zweite Lumen ein Führdraht im Sinne eines Platzhalters bis zum Zielpunkt vorgeschoben werden, der bei einem nochmals erforderlichen Versuch als Leitschiene benutzt werden kann und den Fangkorbkatheter in die Zielposition geleitet. Ein weiterer Vorteil ist, daß jederzeit über das zweite Lumen Medikamente oder Kontrastmittel appliziert werden können, die zum Beispiel bei der Lokalisation des zuHowever, with the current invention, a guide wire can be pushed through the second lumen as a placeholder to the target point, which can be used as a guide rail if another attempt is required and guides the basket catheter to the target position. Another advantage is that medication or contrast media can be administered at any time through the second lumen, for example to help localize the area to be treated.

extrahierenden Materials behilflich sind. Damit die Punktionsweise des Fangkorbs nicht durch den Draht behindert wird, liegt das Austrittsloch des zweiten Lumens seitlich proximal des Korbes ( Pig. 2). Außerdem sollte der Draht im zweiten Lumen nur im geschlossenen Zustand des Pangkorbs vorgeschoben werden ( Fig. 3).extracting material. To ensure that the puncture of the collecting basket is not hindered by the wire, the exit hole of the second lumen is located laterally proximal to the basket ( Fig. 2). In addition, the wire should only be advanced in the second lumen when the collecting basket is closed ( Fig. 3).

Folgendes Anwendungsbeispiel soll den Sachverhalt und den Sinn der Erfindung verdeutlichen: Bei Cholezystektomien werden routinemäßig sogenannte Gallen-T-Drainagen im Ductus choledochus belassen. Sollten sich wider Erwarten postoperativ noch Gallengangskonkremente im Ductus choledochus finden lassen, können diese nach Einwechseln der T-Drainage durch ein Fangkorbkathetersystem extrahiert werden. Jedoch ist nur ein Konkrement über diesen Weg zu extrahieren, weil bei der Extraktion das gesamte Kathetersystem entfernt werden muß. Durch die Erfindung ist es möglich, mittels eines über das zweite Lumen vorgebrachten Drahtes als Leitschiene den Pangkorbkatheter erneut im Zielgebiet zu plazieren und beliebig häufige Extraktionsversuche bei beliebig vielen verbliebenen Konkrementen durchzuführen.The following application example should clarify the facts and the purpose of the invention: During cholecystectomies, so-called bile T-drains are routinely left in the ductus choledochus. If, contrary to expectations , bile duct stones are still found in the ductus choledochus postoperatively, they can be extracted using a basket catheter system after replacing the T-drain. However, only one stone can be extracted in this way because the entire catheter system has to be removed during extraction. The invention makes it possible to place the basket catheter in the target area again using a wire inserted through the second lumen as a guide rail and to carry out extraction attempts as often as desired on any number of remaining stones.
