Abstract
An aspiration catheter arrangement for aspiration of thrombi and emboli from blood vessels has a central catheter (2) and an outside catheter (1) surrounding it coaxially. A guide wire (4) and a dilator (3) are provided for inserting the catheter arrangement into a vessel and for dilating same. A blood clot is removed by means of a vacuum applied to the central catheter (2). If the central catheter (2) becomes clogged by the blood clot during the aspiration procedure, the central catheter (2) can be extracted out of the outside catheter (1) and replaced by a new central catheter (2). This new central catheter (2) can be connected to the aspiration device and the process is then continued. Instead of inserting a new central catheter (2), the aspiration process can also be continued through the outside catheter (1) by connecting the latter to the aspiration device after removing the central catheter (2).
