Exclusion Criteria:

General Exclusion Criteria

1. Currently enrolled in another investigational device or drug trial that has not completed the primary endpoint or that clinically interferes with the current study endpoints.
2. A previous coronary interventional procedure of any kind within 30 days prior to the procedure.
3. Female patients of childbearing potential known to be pregnant.
4. Patients undergoing cardiopulmonary resuscitation.
5. Cardiogenic shock (SBP <80 mmHg for >30 minutes, or requiring IV pressors or emergency IABP for hypotension).
6. The subject requires multivessel PCI at time of index procedure or any staged procedure of the target vessel within 9 months or any non-target vessel within 30 days post-procedure.
7. The target lesion requires treatment with a device other than PTCA prior to stent placement (such as, but not limited to, directional coronary atherectomy, excimer laser, rotational atherectomy, etc.). Thrombus aspiration may be used per operator discretion.
8. Attempted thrombolysis.
9. Co-morbid condition(s) that could limit the subject's ability to participate in the trial or to comply with follow-up requirements, or impact the scientific integrity of the trial.
10. Concurrent medical condition with a life expectancy of less than 12 months.
11. Known left ventricular ejection fraction (LVEF) < 25% at the most recent evaluation (prior to the index hospitalization).
12. History of cerebrovascular accident or transient ischemic attack in the last 6 months.
13. Active peptic ulcer or active gastrointestinal (GI) bleeding.
14. History of bleeding diathesis or coagulopathy or inability to accept blood transfusions.
15. Known hypersensitivity or contraindication to aspirin, heparin or bivalirudin, clopidogrel or ticlopidine, cobalt, nickel, or sensitivity to contrast media, which cannot be adequately pre-medicated.
16. Known serum creatinine level > 2.5 mg/dl, eGFR <30, or hemodialysis dependent.

Angiographic Exclusion Criteria

1. Unprotected left main coronary artery disease (obstruction greater than 60% in the left main coronary artery that is not protected by at least one non-obstructed bypass graft to the left anterior descending (LAD) or left circumflex (LCX) artery or a branch thereof).
2. Multi-vessel intervention required during the index procedure.
