General Inclusion Criteria:

• Acceptable candidate for CABG.

Angiographic Inclusion Criteria:

• Target lesion diameter stenosis >= 50% and <= 99% (visual estimate or on-line QCA).
• Target lesion <= 12 mm in length (visual estimate or on-line QCA).
• Target vessel >= 3.0 mm and <= 3.5 mm in diameter (visual estimate or on-line QCA).

General Exclusion Criteria:

• Known sensitivity to paclitaxel.
• Patient has received paclitaxel or other anti-mitogenic agent within 12 months prior to planned enrollment in the study.
• Patient has previous stent procedure with any drug-coated or drug-eluting stent device.
• Patient has undergone any coronary intervention within 30 days prior to stent placement associated with this protocol.
• Patient anticipates planned additional intervention (staged procedure) to any non-target coronary vessel within 45 days after the stent placement associated with this protocol.
• MI within 72 hours of planned stent placement.
• Left ventricular ejection fraction (LVEF) of < 30%.
• Stroke within the past 6 months.
• Acute or chronic renal dysfunction (creatinine >1.7 mg/mL or >150 µmol/L).
• Acetylsalicylic acid and/or clopidogrel and/or ticlopidine are contraindicated.
• Leukopenia (leukocytes <3.5 x 109/liter).
• Thrombocytopenia (platelets <100,000/mm3).
• Active peptic ulcer or active gastrointestinal (GI) bleeding.
• Known allergy to stainless steel.
• Previously enrolled in the NIRx(TM) Coronary Stent Clinical Safety and Performance Study.
• Currently enrolled in another investigational device or drug study and has not completed the required follow-up period, or has completed all other study-required follow-up less than 30 days prior to enrollment in this study.
• Patient is lactating, has a positive pregnancy test within 7 days of planned stent placement, or intends to become pregnant during the study (only applies to female patients of child-bearing potential).
• Life expectancy of less than 24 months because of other medical conditions.
• Co-morbid condition(s) that could limit the patient's ability to participate in the study or comply with follow-up requirements or co-morbid condition(s) that could impact the scientific integrity of the study.

Angiographic Exclusion Criteria:

• Unprotected left main coronary artery disease (or obstruction greater than 50% in the left main coronary artery that is not protected by at least 1 non-obstructed bypass graft to the left anterior descending [LAD] or circumflex artery or a branch thereof).
• Target lesion is in a previously stented segment.
• Target vessel was treated with directional coronary atherectomy, laser, or transluminal extraction catheter prior to stent placement.
• Target lesion is ostial in location (within 3 mm of vessel origin).
• Target site of stent placement has side branches >2.0 mm in diameter.
• Target lesion is severely calcified (by visual estimate)
• Target vessel has closed abruptly or is threatening closure.
• Target lesion is located within or immediately distal to a >60° bend in the vessel.
• Target vessel has diffuse disease requiring more than one 15 mm stent for full lesion coverage.
• Target lesion involves a bifurcation where a branch vessel greater than 2.0 mm in diameter originates (either stenosis of both main vessel and major branch or stenosis of just major branch).
• Target lesion has excessive tortuosity unsuitable for stent delivery and deployment.
• Target lesion is located within a saphenous vein bypass graft.
• Target lesion is located in a vessel section supplied by distal graft.
