NanoCross BTK, a Prospective, Non-randomized, Multicenter, Controlled Trial Evaluating the Performance of the NanoCrossTM .014 Balloon Catheter in Infrapopliteal Lesions

This is an interventional treatment trial for Peripheral Arterial Disease focused on measuring Peripheral Arterial Disease, Infrapopliteal lesions, balloon catheter Read More

Inclusion Criteria:

• Patient has a projected life-expectancy of at least 12 months
• Patient is eligible for treatment with the NanoCrossTM .014 balloon catheter (Covidien)
• Male, infertile female, or female of child bearing potential practicing an acceptable method of birth control with a negative pregnancy test within 7 days prior to study procedure
• De novo lesion or restenotic lesion after PTA in the infrapopliteal arteries,suitable for endovascular therapy
• Total target lesion length minimally 100mm
• Target vessel diameter visually estimated to be >1.5mm and <4.0mm
• Guidewire and delivery system successfully traversed lesion

• Any previous surgery in the target vessel (including prior ipsilateral crural bypass)
• Aneurysm in the target vessel
• Target lesion has severe calcification as determined by physician's discretion
• Non-atherosclerotic disease resulting in occlusion (e.g. embolism, Buerger's disease, vasculitis)
• Severe medical comorbidities (untreated CAD/CHF, severe COPD, metastatic malignancy, dementia, etc) or other medical condition that would preclude compliance with the study protocol or 1-year life expectancy

• Septicemia or bacteremia
• Any previously known coagulation disorder, including hypercoagulability
• Contraindication to anticoagulation or antiplatelet therapy

• Patient with known hypersensitivity to heparin, including those patients who have had a previous incidence of heparin-induced thrombocytopenia (HIT) type II
• Currently participating in another clinical research trial
• Angiographic evidence of intra-arterial thrombus or atheroembolism from inflow treatment
• Target lesion access not performed by transfemoral approach.
