The primary objectives of the study are to evaluate the safety and 6-month patency of the bioabsorbable MAGIC EXPLORER stent in patients with stenotic or occlusive atherosclerotic disease of the infrapopliteal arteries. Secondary endpoints are the procedural success, patency at all follow-ups, late lumen loss and limb-salvage rate. Peri-procedural complications (within 24 hours) will be evaluated. Furthermore, data of the balloon catheter PLEON EXPLORER will be collected to demonstrate its effectiveness and safety.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '50 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Stenotic (\\> 50%) or occlusive atherosclerotic disease of the infrapopliteal arteries\n* Length of lesion \\< 20mm (less than one stent length)\n* Reference vessel diameter should be 3.0-3.5 mm\n* A maximum of two lesions in one infrapopliteal vessel treated within the study, or in two vessels of two different legs.
