  • Patient has acute thrombophlebitis, deep vein thrombosis or chronic venous insufficiency in either extremity

  • Target extremity has been previously treated with open surgical revascularization (bypass or endarterectomy)
  • Target vessel has been previously treated with stent, laser, atherectomy, surgical bypass, or endarterectomy
  • Total occlusion (100% DS) of the ipsilateral inflow artery
  • Angiographic evidence of thrombus in the target vessel

  • Target lesion is within or adjacent to an aneurysm
  • Patient has angiographic evidence of thromboembolism or atheroembolism from treatment of an ipsilateral iliac lesion or from crossing or pre-dilating the target lesion
  • Target lesion has moderate-to-severe calcification
  • Target lesion with > 30% residual stenosis following pre-dilatation
