Belgian-Italian Trial to Evaluate the Efficacy and Safety of Below The Knee (BTK) Treatment With the Luminor 14 Paclitaxel Coated Percutaneous Transluminal Angioplasty Balloon Catheter of iVascular

Inclusion Criteria: * Males or non-pregnant females ≥ 18 years of age at the time of consent. Females of childbearing potential have a negative pregnancy test \<7 days before the procedure and are willing to use a reliable method of birth control for the duration of study participation. Female participants will be exempted from this requirement in case they are sterile, infertile or have been post-menopausal for at least 12 months * Subject has been informed of and understands the nature of the study and provides signed informed consent to participate in the study. If the subject possesses the ability to understand and provide informed consent but due to physical inability, the subject cannot sign the informed consent form. An impartial witness may sign on behalf of the subject. * Willing to comply with all required follow-up visits * Rutherford Classification 5 * Significant degree of stenosis \>70% or chronic total occlusion (CTO) * Infrapopliteal lesion: P3 to the ankle-joint level (not below-the-ankle (BTA)); full length lesions or tandem lesions are allowed * Wound, Ischemia, foot Infection (WIfI) tissue loss grade 1-2 at baseline * WIfI foot infection grade of 0-2 at baseline * WIfI ischemia grade 2-3 at baseline * Estimated life expectancy ≥ 1 year * Multiple lesions can be treated if they are located in separate vessels per standard of care but only one (1) BTK vessel can be considered as the target lesion/vessel and need to be treated according the Clinical Investigation Protocol (CIP) guidelines. * Target vessel should give direct or indirect run-off to the foot (clearly documented in a foot/BTA angiogram) * Patients with in-flow lesions can be included if the lesions are treated successfully (residual stenosis ≤30%) with the same drug coated balloon (DCB) platform, bail-out stenting with a bare-metal stent (BMS). * Successful pre-dilatation of the target lesion (≤30% residual stenosis) Exclusion Criteria: * Previous bypass graft in the target limb * Acute limb ischemia, defined as symptom onset during less than 14 days prior to the index procedure * Prior or planned above-the-ankle amputation to the target limb (this does not apply to ray amputation of ≤2 digits, simple digital amputations or ulcer debridement) * Previous DCB treatment in target vessel 6 months prior to index procedure * WIfI tissue loss grade 0 or 3 at baseline * WIfI foot infection grade 3 at baseline * WIfI ischemia grade 0-1 at baseline * Any systemic infection or immunocompromised state. Patients with an ascending infection/deep foot infection or abscess/white blood count (WBC)≥12.000/or febrile state or C reactive protein (CRP)\>5mg/L * Endovascular or surgical procedure (not including diagnostic procedures, planned simple digital amputation or wound debridement) to the target limb within 30 days after the index procedure * Existing stent implant in the target vessel * Use of alternative therapies: atherectomy, cutting/scoring balloons, laser, … * Known coagulopathy, hypercoagulable state, bleeding diathesis, other blood disorder, or a platelet count less than 80.000/μL or greater than 500.000/μL * Any subject in which antiplatelet, anticoagulant or thrombolytic therapy is contraindicated * Myocardial infarction, coronary thrombolysis or angina less than 30 days prior to the index procedure * History of stroke or transient ischemic attack (TIA) less than 90 days prior to the index procedure * Known hypersensitivity or contraindication to nickel-titanium alloy (Nitinol) * Has other comorbidities that, in the opinion of the investigator, would preclude them from receiving this treatment and/or participating in study-required follow-up * Patients on haemodialysis * Known hypersensitivity or allergy to contrast agents that cannot be medically managed * Known hypersensitivity or allergy to heparin, aspirin, paclitaxel, clopidogrel or other antiplatelet/anticoagulant therapies * Inadequate inflow lesion treatment (\>30% residual stenosis) * Inadequate result of pre-dilatation (\>30% residual stenosis) * Inadequate run-off to the foot * Bilateral BTK enrolment in this study
