A Prospective, Multi-centre, Sinlge Arm, Post-market Registry to Assess the Clinical Performance and Safety of the Passeo-18 Lux Paclitaxel Releasing Balloon Catheter in Infrainguinal Arteries

This study is a prospective, multicenter, single arm, post-market registry subject to all the patient group with the relevant indications, where follow-up is performed in 1, 6, 12 (including angio follow up), and 24 month. The Passeo-18 Lux DCB including all the target patient group, is subject to every disease requiring revascularization in the infrainguinal arteries and is going to use the Passeo-18 Lux DCB.

The subject will receive percutaneous intervention using Passeo-18 Lux DCB according to the standard care guideline of this hospital. All complications and adverse events occurring during the operation will be recorded thoroughly. During the intervention, the number of lesions to be treated with Passeo-18 Lux will be determined carefully under judgment of the PI (When using more than one Passeo-18 Lux in a patient, maximum drug release recommended in the IFU should be considered.) The target lesion which is compose of one or several small lesions treatable with a balloon catheter is defined as a "treatment segment". The results of all the lesions treated with Passeo-18 Lux for the first time (regardless of which side limb) are going to be documented in eCRF, through which final results will be analyzed. All complications and adverse events from the intervention will be recorded thoroughly and reported to IRB according to the prescribed form.

Stent insertion into the lesion finishing treatment with drug coated balloon catheter will be determined by the study physician. For the subjects follow-up via phone call or clinical assessment will be conducted under below schedule. In this study the subjects who require stent insertion will not be classified as treatment failure. Before discharge of the subjects, medical prescription will follow the standard of care of this hospital, which will be documented. All the postoperative complications and adverse events will be recorded thoroughly and reported to IRB via suitable form. The subjects will be administered with proper anticoagulant, antiplatelet drug, and blood vessel dilator according to common and standard care guideline. The treatment follows the guideline described in IFU of Passeo-18 Lux DCB.

A subject does not have to participate in this study for treatment of the stenosed lower limb blood vessel. For example, there are a lot of devices available for treatment of the subject, including standard drug coated balloon, laser, and stent. The study physician will provide sufficient explanation on these alternative therapies for his/her understanding. Even though a subject decided not to participate in this study, it would not affect current and future treatment that he/she receives.

As the subjects of this study participate in in this study voluntarily according to their own will, they can discontinue the participation without any disadvantage or limitation at any time when they desire. They will not receive any disadvantage in later treatment from that. However the information collected during participation may be able to be used as it was anonymized. When a subject discontinued participation of study early, the participation should be terminated after completing preparation of eCRF as soon as possible. Also, The principal investigator regards a case as failure in follow-up of a subject up to for 24 months. In failing the follow-up, the principal investigator should record the failure of follow-up on the CRF.
