    • A cutting balloon catheter assembly (100) including a dual lumen catheter (130) having a distal end (134), an inflation/deflation lumen (138) and a second or guidewire lumen (136). The assembly further includes an inflatable balloon (110) having an interior cavity (116) and an expandable covering (120) disposed about the balloon wherein the covering has an array of cutting edges. In the assembly, the balloon (110) is fixedly connected to the distal end (134) of the catheter and the interior cavity (116) of the balloon (110) is in fluid communication with the first lumen (138) of the catheter (130). A method of removing obstructions (149) from vessel walls (154) using the present invention is also disclosed wherein the cutting edges abrade the stenoses, plaque or lesions along the vessel walls, when the catheter assembly is reciprocally moved longitudinally or rotationally after inflation of the balloon.
    • 一种切割气囊导管组件(100),其包括具有远端(134),充气/放气腔(138)和第二或导丝腔(136)的双腔导管(130)。 组件还包括具有内部空腔(116)和围绕球囊设置的可膨胀覆盖物(120)的可膨胀气囊(110),其中所述覆盖物具有切​​割刃阵列。 在组件中,球囊(110)固定地连接到导管的远端(134),球囊(110)的内腔(116)与导管的第一腔(138)流体连通 130)。 还公开了使用本发明从血管壁(154)除去障碍物(149)的方法,其中当导管组件在通气后纵向或旋转地往复运动时,切削刃磨损沿着血管壁的狭窄,斑块或损伤 气球。
