Arm Intervention/treatment
Experimental: PTA catheter Device: percutaneous transluminal angioplasty balloon catheter
Other Names:
  • PTA catheter
  • trade name: Iris

Primary Outcome Measures :
  1. technical success rate of PTA procedure [ Time Frame: instant ]
    1. successfully pass lesion(s)
    2. successfully dilate lesion(s)( diameter of balloon reach at least 90% of the nominal diameter)
    3. successfully retrieve

    The definition of technical success rate of PTA procedure is that, all of the above 3 point are successful

Secondary Outcome Measures :
  1. safety assessment [ Time Frame: day 2 to day 10 after procedure or hospital discharge ]
    1. relevant balloon complications occurred during procedure(failure of balloon inflation, rupture of the balloon, failure of balloon deflation, failure of withdrawn, catheter fracture, etc.).
    2. Relevant major vascular complications occurred during procedure (rupture of blood vessels and acute vascular occlusion caused by dilation).
