A Prospective, Single Center, Case-cohort Study Using the Orchid Drug Coated Balloon for Post-Dilatation of the Stent for Treatment of Long Lesions in Femoropopliteal Arteries
To compare the efficacy and safety of stent angioplasty with Orchid 035 Drug Coated Dilatation (DCB) and Plain Old Balloon Angioplasty (POBA) for post-dilatation for long (\>10cm) femoropopliteal chronic total occlusion.
• Age ≥18 years;
• The subject is legally competent and able to understand the information on the study, has been informed of the nature, the scope and the relevance of the study, voluntarily agrees to participation and the study's provisions, and has duly signed the Informed Consent Form (ICF);
• Rutherford Category 2-4;
• Target de novo lesion(s) or non-stented restenotic lesion(s) has angiographic evidence of long-term occlusion (by visual estimate ≥10cm) and is amenable to treatment with stents placement;
• Patients must be able to be treated with DCB or POBA for post-dilation;
• Target vessel reference diameter is 4.0-7.0 mm (by visual estimate) and able to be treated with available device size matrix;
• At least one patent native outflow artery to the ankle free from significant lesion (≥50% stenosis) as confirmed by angiography (treatment of outflow disease is NOT permitted; treatment of in-flow disease is permitted prior to treatment with stents placement).
• No other prior vascular interventions (including contralateral limb) within 2 weeks before and/or planned 30 days after the protocol treatment, with the exception of remote common femoral patch angioplasty separated by at least 2 cm from the target lesion;
• Female subjects of childbearing potential have a negative urine or serum pregnancy test within 7 days prior to index procedure;
⁃ Lesion location starts ≥1 cm below the common femoral bifurcation and P1 popliteal artery.
