The purpose of this trial is to evaluate the clinical safety and efficacy of the Polymer-Free Drug-Eluting coronary stent system for the treatment of de novo lesions in native coronary arteries with a reference vessel diameter (RVD) that allows use of stents between 2.25 and 3.50 mm in diameter.

Inclusion Criteria:

• Must be an acceptable candidate for percutaneous coronary intervention, stenting, & emergent coronary artery bypass graft (CABG) surgery
• Must have evidence of ischemic heart disease
• Must require treatment of either a) a single target lesion amenable to treatment with a 2.25 mm - 3.50 mm stent OR b) two target lesions located in separate target vessels, with at least one of the target lesions amenable to treatment with a 2.25 mm - 3.50 mm mm study stent
• Target lesion(s) must be de novo lesion(s) in native coronary artery(ies)

Exclusion Criteria:

• Known hypersensitivity or contraindication to aspirin, heparin and bivalirudin, thienopyridines, cobalt, nickel, platinum, iridium, chromium, molybdenum, polymer coatings (e.g. BioLinx) or a sensitivity to contrast media, which cannot be adequately pre-medicated
• History of an allergic reaction or significant sensitivity to drugs such as zotarolimus, rapamycin, tacrolimus, everolimus, or any other analogue or derivative
• History of a stroke or transient ischemic attack (TIA) within the prior 6 months
• Active peptic ulcer or upper gastrointestinal (GI) bleeding within the prior 6 months
• History of bleeding diathesis or coagulopathy or will refuse blood transfusions
• Concurrent medical condition with a life expectancy of less than 5 years
• Currently participating in an investigational drug or another device trial that has not completed the primary endpoint
• Documented left ventricular ejection fraction (LVEF) < 30% at the most recent evaluation
