  • Quality of life assessment [ Time Frame: 30 days, 6 and 12 months ]
    Quality of life assessment by EQ5D questionnaire at 30 days, 6 and 12 months as change from baseline

  • Device success [ Time Frame: Post procedure ]
    Device success is defined as successful delivery, balloon inflation, deflation and retrieval of the intact study device without burst below the rated burst pressure (RBP).

  • Procedural success [ Time Frame: Post procedure ]
    Procedural success is defined as residual stenosis of ≤ 50% (non-stented subjects) or ≤ 30% (stented subjects) by core lab assessment.

  • Clinical success [ Time Frame: Post procedure ]
    Clinical success is defined as procedural success without procedural complications (death, major target limb amputation, thrombosis of the target lesion, or TVR) prior to discharge.

  • Days of hospitalization due to the target lesion [ Time Frame: 6 and 12 months ]
    Days of hospitalization due to the target lesion from procedure through 6 and 12 months
