Patient has a known hypersensitivity or contraindication to aspirin, both heparin and bivalirudin, both clopidogrel and ticlopidine, Novolimus, PLLA polymers or contrast sensitivity that cannot be adequately pre-medicated Elective surgery is planned within the first 6 months after the procedure that will require discontinuing either aspirin or clopidogrel Patient has a platelet count < 100,000 cells/mm3 or > 700,000 cells/mm3, a WBC of < 3,000 cells/mm3, or documented or suspected liver disease. Patient has known renal insufficiency (e.g., serum creatinine level of more than 2.5 mg/dL, or patient on dialysis) Patient has a history of bleeding diathesis or coagulopathy or will refuse blood transfusions Patient has had a cerebrovascular accident (CVA) or transient ischemic neurological attack (TIA) within the past six months Patient has had a significant GI or urinary bleed within the past six months Patient has extensive peripheral vascular disease that precludes safe 6 French sheath insertion Patient has other medical illness (e.g., cancer or congestive heart failure) or known history of substance abuse (alcohol, cocaine, heroin etc.) that may cause non-compliance with the clinical study plan, confound the data interpretation or is associated with a limited life expectancy (i.e., less than one year) Patient is already participating in another clinical study Women of childbearing potential who have not undergone surgical sterilization or are not post-menopausal (defined as amenorrheic for at least one year) as well as women who are pregnant or nursing Patient is unable to give their consent, is legally incompetent, or is institutionalized by virtue of an order issued by the courts or other authority Angiographic Exclusion Criteria Target lesion(s) meets any of the following criteria: Aorto-ostial location Left main location Located within 5 mm of the origin of the LAD or LCX Located within an arterial or saphenous vein graft or distal to a diseased arterial or saphenous vein graft Lesion involving a side branch >2mm in diameter or bifurcation Previous placement of a scaffold proximal to or within 10 mm of the target lesion Total occlusion (TIMI flow 0), or TIMI flow < 1 Excessive tortuosity proximal to or within the lesion Angulation (≥ 45o) proximal to or within the lesion Calcification moderate or heavy Previous intervention restenosis The target vessel contains visible thrombus Another clinically significant lesion (>40%) is located in the same major epicardial vessel as the target lesion Patient has a high probability that a procedure other than pre-dilatation and scaffolding and (if necessary) post-dilatation will be required at the time of index procedure for treatment of the target vessel (e.g. atherectomy, cutting balloon or brachytherapy)
