Over the last several years, extremely low-profile balloon-on-a-wire catheters have extended the limits of coronary angioplasty. However, the first such fixed-wire catheter, the Probe, experienced a number of mechanical failures, causing the manufacturer to reconfigure the catheter as the Probe III. The current study was therefore undertaken to assess the safety and efficacy of this new device in a variety of cases. The Probe III catheter was used as a primary dilatation device in 157 lesions in 113 patients over a three and one-half month period. One-hundred-six (93%) of the procedures were successful. There were no mechanical failures. The low profile and enhanced trackability of the Probe III catheter led to a high rate of procedural success in a variety of lesions, including extremely tight lesions, distal stenoses, bifurcation lesions, and bend-point lesions. The low profile and enhanced trackability also enabled excellent visualization, as well as quick and successful angioplasty in most patients.
在过去几年中，极细的带导丝球囊导管扩展了冠状动脉血管成形术的极限。然而，首个此类固定导丝导管Probe出现了一些机械故障，导致制造商将该导管重新设计为Probe III。因此，开展了本项研究以评估这一新型器械在各种病例中的安全性和有效性。在三个半月的时间里，Probe III导管被用作113例患者157处病变的主要扩张器械。106例（93%）手术成功。未发生机械故障。Probe III导管的低外形和增强的可跟踪性使得在各种病变中，包括极严重狭窄病变、远端狭窄、分叉病变和弯曲点病变，手术成功率很高。低外形和增强的可跟踪性还能实现极佳的可视化效果，并且在大多数患者中能快速成功地完成血管成形术。
