A technical description of a catheter system is given for percutaneous dilatation of experimental stenosis in small ateries (e.g. left coronary artery). The system consists of two catheters: the first is positioned into the orifice of the small artery and guides the second, double-lumen-dilatation catheter into the artery. During the manipulation ischemia in the peripheral area is prevented by contineous perfusion with oxygenated blood taken from the femoral artery by a roller-pump. The catheter system was tested in canine experiments.
给出了一种用于经皮扩张小动脉（如左冠状动脉）实验性狭窄的导管系统的技术描述。该系统由两根导管组成：第一根导管置于小动脉的开口处，并引导第二根双腔扩张导管进入动脉。在操作过程中，通过滚轴泵从股动脉采集含氧血液进行持续灌注，以防止周边区域出现局部缺血。该导管系统在犬类实验中进行了测试。
