The Magnarail probing catheter (Schneider Europe), a new tool for angioplasty of chronic total coronary occlusions, consists of a 135 cm/3.4 French single lumen shaft with the distal 17 cm (4.5 French) featuring a double lumen (Monorail section). The long lumen serves for contrast medium injection and pressure measurements. The short lumen accepts the guide wire and braces it to cross the occlusion. Once the lesion passed, the Magnarail probing catheter quickly can be exchanged for a balloon catheter. In case of failure to pass with the guide wire, no balloon is wasted.
Magnarail 探测导管（施奈德欧洲公司）是用于慢性完全性冠状动脉闭塞血管成形术的一种新工具，它由一根135厘米/3.4法式单腔导管轴组成，其远端17厘米（4.5法式）为双腔（单轨段）。长腔用于注射造影剂和测量压力。短腔用于容纳导丝并支撑其穿过闭塞病变。一旦通过病变部位，Magnarail探测导管可迅速更换为球囊导管。如果导丝未能通过，则不会浪费球囊。
