This is a prospective, open label, multicenter, single arm, first in human clinical study. Patients with infra-inguinal peripheral arterial disease appropriate for treatment with a femoro-popliteal stent will be enrolled. The patients will be treated with the ChampioNIR Stent System. All implanted patients will be followed up at 30 days and 6, 12, 24 and 36 months. The follow-up visits will include patency evaluation by duplex ultrasound

RECRUITINGPrimary patency of the target lesion
Primary patency of the target lesion defined as the absence of target lesion restenosis (defined by Duplex ultrasound (US) peak systolic velocity ratio (PSVR) ≥2.4).
Time frame: 6 months
Primary safety endpoint
Composite rate of freedom from all-cause death, target vessel revascularization or any amputation of the index limb through 30 days following stent implantation
Time frame: 30 days
Primary patency
Primary patency defined by Duplex US peak systolic velocity ratio (absence of restenosis which defined by Duplex US PSVR ≥2.4)
Time frame: 30 days and 12 months
Acute device success
Acute device success, defined as achievement of a final residual diameter stenosis of \<30% by Quantitative Angiography (QA), using the assigned treatment only
Time frame: During the index procedure
Acute procedural success
Acute procedural success, defined as device success with \<30% residual stenosis immediately after stent placement or mean trans-stenotic pressure gradient \<5 mmHg, and without the occurrence of death, amputation or repeat revascularization of the target lesion during the hospital stay
Time frame: During the index procedure
Acute technical success
Acute technical success, defined as the attainment of \<30% residual stenosis by QA by any percutaneous method as determined by the angiographic core laboratory
