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

The objective of this clinical investigation is to assess the safety and efficacy of the Luminor-14 DCB for the treatment of infrapopliteal lesions patients with critical limb ischemia. The patients will be selected based on the investigator's assessment, evaluation of the underlying disease and the eligibility criteria. The patient's medical condition should be stable, with no underlying medical condition which would prevent them from performing the required testing or from completing the study. Patients should be geographically stable, willing and able to cooperate in this clinical study, and remain available for long term follow-up. The patient is considered enrolled in the study after obtaining the patients informed consent, if there is full compliance with the study eligibility criteria and after successful guidewire passage through the study target lesion. Prior to the index procedure the following will be collected: an informed consent for data collection, demographics, medical history, medication record, physical examination, clinical category of acute limb ischemia (Rutherford category), the resting ankle-brachial index (ABI), life quality and if applicable a wound assessment. During the procedure the guidewire will cross the entire study lesion after which the lesion will be assessed through angiography. A pre-dilatation with a standard non-drug-coated balloon will be performed followed by a dilatation of the lesion with a Luminor-14 balloon (iVascular). If dilatation was not successful (\>30% stenosis, perforation, occlusive or flow limiting dissection) prolonged inflation should be attempted after which bail-out stenting with a non-drug-coated dedicated BTK stent is allowed in case of inadequate results. The regular follow-up is necessary to monitor the condition of the patient and the results of the procedure. Patients will be invited on weekly follow-up, with special attention to wound healing status at each visit until the wound is completely healed. The other required follow-up visits are 1,6 and 12 months follow-ups. During these visit the following data will be collected: medication record, physical exam, wound assessment and healing status, quality of life, duplex ultrasound of target vessel and possible adverse events.
