Cardiovascular Systems CSII, a medical device company developing and commercializing innovative interventional treatment systems for vascular disease, today announced publication of 12-month results from its CALCIUM 360° study in the Journal of Endovascular Therapy, August 2012. CALCIUM 360° is a prospective, randomized, multi-center study of 50 patients (64 lesions), comparing one-year safety and efficacy of CSI's Diamondback 360° atherectomy device followed by percutaneous transluminal angioplasty (PTA), versus PTA alone, to treat calcified infrapopliteal lesions in patients with critical limb ischemia.
