4. Degree of stenosis ≥ 70% by visual angiographic assessment
5. RVD is between 2.5 - 3.75mm
6. Total target lesion length (or series of lesion segments) to be treated is ≤ 140 mm (Note: Lesion segment(s) must be fully covered with up to two DES BTK stents)
7. Target vessel(s) reconstitute(s) at or above the stenting limit zone (4cm above the ankle joint)
8. Target lesion(s) is in an area that may be stented without blocking access to patent main branches
9. Treatment of all above the knee inflow lesion(s) is successful prior to treatment of the target lesion
10. Guidewire has successfully crossed the target lesion(s)

Exclusion Criteria:

Clinical exclusion criteria

1. Life expectancy ≤ 1year
2. Stroke ≤ 90 days prior to the procedure date
3. Prior or planned major amputation in the target limb
4. Previous surgery in the target vessel(s) (including prior ipsilateral crural bypass)
5. Previously implanted stent in the target vessel(s)
6. Failed PTA of target lesion/vessel ≤ 60 days prior to the procedure date
7. Heel gangrene
8. Subject has a platelet count ≤ 50 or ≥ 600 X 103/µL ≤ 30 days prior to the procedure date
9. NYHA class IV heart failure
10. Subject has symptomatic coronary artery disease (i.e., unstable angina)
11. History of myocardial infarction or thrombolysis ≤ 90 days prior to the procedure date
12. Non-atherosclerotic disease resulting in occlusion (e.g., embolism, Buerger's disease, vasculitis)
13. Subject is currently taking Canagliflozin
14. Body Mass Index (BMI) <18

20. Known hypersensitivity to heparin
21. Subject is on a high dose of steroids or is on immunosuppressive therapy
22. Subject is currently participating, or plans to participate in, another investigational study that may confound the results of this study

Intraoperative exclusion criteria

1. Angiographic evidence of intra-arterial acute/subacute thrombus or presence of atheroembolism
2. Treatment required in > 2 target vessels (Note: a target lesion originating in one vessel and extending into another vessel is considered 1 target vessel)
3. Treatment requires the use of alternate therapy in the target vessel(s)/lesion(s), (e.g., atherectomy, cutting balloon, re-entry devices, laser, radiation therapy)
4. Aneurysm is present in the target vessel(s)
5. Extremely calcified lesions
6. Failure to obtain <30% residual stenosis in a pre-existing lesion
