A new catheter system was designed for percutaneous fragmentation of large pulmonary emboli. The device consists of an impeller rotating at high speed at the center of a self-expandable basket at the tip of a 7-F catheter. The highly flexible catheter was able to reach all tested embolus sites in a glass model of the pulmonary arterial tree. Embolus fragmentation was quick and thorough. Particles in the effluent larger than 10 microns accounted for only about 9% of the treated embolus weight. Wall contact with the rotating impeller was not observed. The impeller-basket catheter promises to be a useful tool for percutaneous treatment of acute pulmonary embolism.
一种用于经皮破碎大型肺栓塞的新型导管系统被设计出来。该装置由一个叶轮组成，叶轮在一根7F导管尖端的自膨胀篮筐中心高速旋转。这种高度灵活的导管能够到达肺动脉树玻璃模型中所有测试的栓子部位。栓子破碎迅速且彻底。流出物中大于10微米的颗粒仅占所治疗栓子重量的约9%。未观察到旋转叶轮与血管壁接触。叶轮-篮筐导管有望成为经皮治疗急性肺栓塞的有用工具。
