5. Reference vessel diameter (RVD) ≥ 3.5 mm and ≤ 7 mm.

6. Not expected to require further interventional standard of care treatment during study participation (approximately 174 days).

Miscellaneous Inclusion Criteria

1. Anticipated life expectancy >1 year.

2. Has adequate hepatic function defined as total bilirubin < 1.5 mg/dL, serum albumin > 3.0 gm/dL, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 3.0 × upper limit of normal (ULN) or < 5 x ULN for subjects with known hepatic metastases.

3. Has adequate renal function defined as serum creatinine < 2.5 × ULN.

Women who are postmenopausal for at least 1 year or surgically sterile (bilateral tubal ligation, bilateral oophorectomy, or hysterectomy) are not considered to be WOCP.

Male subjects with female sexual partners who are pregnant, possibly pregnant, or who could become pregnant during the study must agree to use condoms at least 30 days after the last dose of study drug. Total abstinence for the same study period is an acceptable alternative.

3. Recent diagnosis of cancer or treatment for cancer within last 12 months.

4. Life expectancy < 12 months.

5. CVA < 1 month prior to screening or any CVA resulting in unresolved walking impairment.

6. STEMI Myocardial infarction < 1 month prior to procedure.

7. Contraindication to contrast media or any study-required medication.

8. Coagulopathy or clotting disorders.

9. Suspected systemic infection affecting target limb.

10. Serum creatinine ≥ 2.5 mg/dL unless dialysis-dependent.

11. Enrollment in a drug study or medical device investigational research study.

12. Previous standard of care treatment to the same target lesion < 3 months prior to study enrollment.

Anatomic Exclusion Criteria

2. Unresolved complication following treatment of inflow lesions, or inflow lesion requiring a stent graft or surgical intervention.

3. Grade 4 or grade 5 stent fracture affecting target stent or proximal to the target stent.

4. Aneurysm within the target vessel.

5. Subjects with (or planned to receive) amputation(s) above the ankle, including major amputation, unilateral or bilateral.

6. Subject is expected to require further interventional standard of care treatment, during study participation (approximately 174 days).

Miscellaneous Exclusion Criteria

1. Standard of care cannot include drug eluting stent (DES).

2. Concurrent enrollment in another investigational drug or device study or has received other investigational drugs within 14 days of enrollment.

3. Had surgery within 4 weeks prior to study treatment except for the interventional standard of care.

4. Has a history of blood clots, pulmonary embolism, or deep vein thrombosis unless controlled by anticoagulant treatment.

5. Has a history of an arterial thromboembolic event within the prior six months including cerebrovascular accident, transient ischemic attack, myocardial infarction, or unstable angina.

6. Has uncontrolled human immunodeficiency virus (HIV) infection or hepatitis B or C.

7. Has any clinically significant infection, i.e., any acute viral, bacterial, or fungal infection that requires specific treatment (anti-infective treatment has to be completed ≥ 7 days prior to study entry).

13. Subject has other severe acute or chronic medical or psychiatric conditions or laboratory abnormalities that may increase the risk associated with study participation or investigation product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for enrollment in this study.

14. Subject has any mental or medical condition that prevents the subject from giving informed consent or participating in the trial.
