Safety and Efficacy Study of Kaname Coronary Stent System for the Treatment of Patients With Coronary Artery Disease

Inclusion Criteria: * Patient is ≥ 18 years old. * Patient is eligible for PCI and acceptable candidate for CABG. * Clinical evidence of ischemic heart disease and/or a positive functional study. Documented stable angina pectoris (CCS 1, 2, 3 or 4) or unstable angina pectoris with documented ischemia (Braunwald Class IB-C, IIB-C, or IIIB-C), or documented silent ischemia. * The target lesion or target vessel meets all the following criteria;a) is a single de novo lesion or restenotic post-PTCA (non-stented) lesion in one native coronary artery.b)The stenosis of target lesion is ≥ 50% and \< 100% c)The target lesion length must be ≤ 25 mm d)The target reference vessel diameter must be suitable for treatment with stents between 2.5 and 4.0 mm long * Patient has been informed of the nature of the study, understands the study requirements and agrees to its provisions and has provided written informed consent as approved by the Institutional Review Board/Ethics Committee of the respective clinical site. * The patient is able to comply with all specified follow-up evaluations. Exclusion Criteria: * Most recent LVEF of the patient is \< 25%. * Known allergies to the following: aspirin, Clopidogrel bisulfate, Prasugrel or Ticlopidine, heparin, cobalt, chromium, nickel, or contrast agent (that cannot be adequately premedicated). * A platelet count \<100,000 cells/mm3 or \>700,000 cells/mm3. * WBC count \< 3500 cells/mm3. * Evidence of MI with positive Troponin within 72 hours of the intended treatment. * Previous PCI (\<30 days) anywhere within the target vessel. * Planned interventional treatment of any non-target vessel \<30 days post-procedure will be required. Planned intervention on the target vessel or on a significant lesion of \> 50% stenosis anywhere within the target vessel after the index procedure will be required. * The target lesion requires treatment with a device other than PTCA balloon prior to stent placement. (e.g. but not limited to directional coronary atherectomy, excimer laser, rotational atherectomy, etc.). * Previous stenting anywhere within the target vessel. * Target vessel has evidence of thrombus. * Excessive tortuousity (\> 60°) of the target vessel proximal to the target lesion (visual estimate). * Either of the following characteristics in the target lesion (visual estimate): a)Ostial target lesion or bifurcation lesion b)Target lesion involves a side branch \> 2mm in diameter c) Target lesion has excessive tortuousity (\> 45°)d)Moderate to severely calcified lesion which can not be successfully predilated e)Target lesion is located in or supplied by an arterial or venous bypass graft f)Significant (\> 40%) stenosis proximal or distal to the target lesion. g) A complete occlusion (TIMI flow 0 or 1). * Target lesion located in left main trunk. * Stroke or transient ischemic attack \< prior 180 days. * Active peptic ulcer or upper GI bleeding \< prior 180 days. * The patient has bleeding hemorrhagic diathesis or coagulopathy. The patient will refuse a blood transfusion. * The patient has a widespread peripheral vascular disease. * Acute or chronic renal dysfunction (creatinine \> 2.0 mg/dl). * The patient requires multiple stent implantations for a tandem lesion. * Life expectancy \< 1 year. * Patient is currently participating in an investigational drug or device study that has not completed the primary endpoint or that clinically interferes with the current study endpoints. Note: Trials requiring extended follow-up for products that were investigational, but have become commercially available since then, are not considered investigational trials. * In the investigators opinion patient has a co-morbid condition(s) that could limit the patient's ability to participate in the study, compliance with follow-up requirements or impact the scientific integrity of the study. * Patient is in cardiogenic shock. * Female of child-bearing potential.
