• Subject must have evidence of acute ST-segment elevation myocardial infarction with TIMI 0 or 1 flow, or visible thrombi (thrombus grade ≥ 3)
• Target lesion(s) must be located in a native coronary artery in the proximal to mid segment with estimated reference diameter of ≥ 2.5 mm and ≤ 4.0 mm.
• Target lesion(s) must be amenable for percutaneous coronary intervention.

Exclusion criteria

• The patient has a known hypersensitivity or contraindication to any of the following medications: Heparin, Aspirin, Clopidogrel, Abciximab, Contrast media (Patients with documented sensitivity to contrast media which can be effectively premedicated with steroids and diphenhydramine [e.g. rash] may be enrolled.

• Gastrointestinal or genitourinary bleeding within the prior 3 months, or major surgery within 2 months.
• Patients with severe LV systolic dysfunction (LVEF<25%) or in cardiogenic shock
• Non-cardiac co-morbid conditions are present with life expectancy <1 year or that may result in protocol non-compliance (per site investigator's medical judgment).
• Patients who are actively participating in another drug or device investigational study, which have not completed the primary endpoint follow-up period.
