It is designed to treat narrows of the femoral- and knee artery.\n\n100 patients at 5 German hospital shall be enrolled. After stent implantation follow-up visits at 6 and 12 month take place.', 'detailedDescription': 'Peripheral arterial disease (PAD) represents a major challenge to physicians in treating the Superficial Femoral (SFA) and Popliteal arteries. These arteries represent a harsh environment for any endovascular device. This disease is characterized by long occlusions with relatively low flow and with the vessels exposed to enormous mechanical stress. During flexing of the knee, the SFA/Popliteal arteries can bend, rotate, elongate and compress dramatically. An ideal stent designed for use in the SFA/Popliteal arteries would offer great ranges of movement while adequately supporting the arteries.\n\nThe FlexStent® stent provides a great range of motions for a highly flexible femoral artery while adequately supporting the vessel. The intended use for the FlexStent® stent is for the treatment of symptomatic femoropopliteal disease, primarily for atherosclerotic de novo native superficial femoral artery lesions.\n\nThe intent of this clinical registry is to demonstrate the efficacy and safety of the FlexStent® stent in patients with superficial femoral/ popliteal artery disease.\n\nHypothesis: the FlexStent® will be safe and efficacious in treating SFA/popliteal artery diseases.\n\nPrimary object: evaluation of efficacy of the FlexStent® measured by the in-stent restenosis using DUS following treatment, 6 and 12 MFU visits.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '35 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Subjects, male or female, must be between the ages of 35 to 85 years inclusive at the time of consent.
