The purpose of the artery preparation concept is to perform regular longitudinal micro-incisions on the inner side of the artery ("scoring") and therefore promote a regular expansion of atheroma by balloon inflation.

Inclusion Criteria:

• Rutherford class of symptom 2 to 5
• Atheromatous ≥ 70 % stenosis or occlusion of SFA and/or PA
• Absence of > 50% residual stenosis of the run-in vessels at the end of procedure
• Presence of at least one patent (no ≥ 50 % stenosis) run-off tibial or fibular vessel to the foot at the end of procedure
• De novo or restenotic lesions, including in-stent restenosis
• Willingness to participate in the study and signature of informed consent

Exclusion Criteria:

• Previous use of a PCB in the lesion during last 15 months
• Extremely calcified lesions, defined by calcification involving ³ 270° of the artery circumference over ³ 15 cm.
• Sub-intimal recanalization
• Tortuous contra-lateral femoral access with difficult cross-over
