A Developmental Study of Waterjet Angioplasty System.

这份报告描述了一项使用水喷射代替激光的经皮腔内血管成形术系统的发展研究。该系统由平板泵和导尿管组成。导管耐压，喷嘴位于末端。采用凝血法制备血栓模型，对靶点损伤兔的主动脉进行实验。手术过程使用细小纤维内窥镜在视频显示器上监视。水射流首先在血栓表面打一个小孔，然后穿透整个血栓。然后冲洗掉碎片，并移走周围船只的其他部分。本实验表明，水射流血管成形术比激光血管成形术有许多优点。

This report described a developmental study of the percutaneous transluminal angioplasty system using the waterjet instead of the laser. The system consisted of planger pump and a catheter. Catheter is pressure durable and has the nozzle at the distal tip. Experiment was carried out with the aorta of rabbit Target lesion as the thrombus was made by blood coagulation. Operative procedure was monitored in the video display using the fine fiberscope. Waterjet make a fine hole on the thrombus surface at first and penetrated through the whole thrombus. Then washed out the debris and remove others of the surroundings vessels. This experiment showed that waterjet angioplasty have many advantages over the laser method.
