Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age ≥18 years.
• Subject must provide written informed consent prior to the treatment of the target lesion.
• Subject must be willing to comply with the specified follow-up evaluation schedule.
• Subject with Rutherford-Becker clinical classification category 2 to 5, with a resting ankle-brachial index (ABI) ≤ 0.9.
• Common femoral, superficial femoral and/or popliteal artery lesion with > 50% stenosis or total occlusion.
• Stenotic or occluded lesion(s) within the same vessel with no length limits.
• De novo or restenotic/occluded lesion(s) including in-stent restenosis, with reference vessel diameter (RVD) ≥ 4.0 mm and ≤ 8.0 mm by visual assessment and no length limits.
• Multiple RENZAN stents could be deployed with a mandatory overlap of 0.5-1 cm.
• A patent inflow artery free from the significant lesion (≥50% stenosis) as confirmed by angiography (treatment of target lesion acceptable after successful treatment of ipsilateral iliac lesions); Successful ipsilateral iliac artery treatment is defined as the attainment of residual diameter stenosis ≤30%, either with PTA or stenting.
• The target lesion(s) can be successfully crossed with a guide wire and dilated up to 1:1 to the proposed stent to be implanted (as per the operator's assessment).
• At least one patent native outflow artery (anterior or posterior tibial or peroneal), free from significant (≥50%) stenosis (as confirmed by angiography), that has not previously been revascularized. The remaining outflow arteries requiring treatment during the same procedure may be treated

You may not qualify if…

• Subject has Rutherford-Becker classification category 6.
• Treatment of lesions requiring the use of adjunctive debulking devices.
• Use of drug-eluting balloon or stent
• Inadequate vessel preparation not achieving a diameter of 1:1 to the stent to be implanted (with ≤20% residual stenosis, as per operator's assessment).
• Concomitant use of different stent platforms
• Any significant vessel tortuosity or other parameters prohibiting access to the lesion and/or preventing the stent delivery.
• Subject with coronary intervention performed less than 90 days prior to or planned within 30 days after the treatment of the target lesion.
• Known allergies or intolerance to nitinol (nickel titanium).
• Any contraindication or known unresponsiveness to dual antiplatelet therapy (DAPT) or anticoagulation therapy.
• Presence of acute thrombus prior to crossing the lesion.
• Thrombolysis of the target vessel within 72 hours prior to the index procedure
• Thrombophlebitis or deep venous thrombus, within the previous 30 days.
• Subject receiving dialysis within the previous 30 days.
• Stroke within the previous 90 days.
• Subject is pregnant or of childbearing potential
• Subject has a life expectancy of less than 1 year.
• Subject is participating in an investigational study that has not reached the primary endpoint at the time of study screening.
• Only one patent outflow artery, with significant stenosis (≥50%) (as confirmed by angiography)
