Brief Summary: The objective of the study is To verify the safety and efficacy of the MDT-4107 Drug-Eluting Coronary Stent in the treatment of de novo lesions in native coronary arteries with a reference vessel diameter (RVD) that allows the use of 2.25mm diameter stents.

Detailed Description: The objective of the study is to verify the safety and efficacy of the MDT-4107 Drug-Eluting Coronary Stent in the treatment of de novo lesions in native coronary arteries with a reference vessel diameter (RVD) that allows the use of 2.25mm diameter stents.

Acute myocardial infarction (MI) within 72 hrs of the index procedure (Q wave myocardial infarction(QWMI)/non Q wave myocardial infarction (NQMI) or any elevation of creatinine kinease myocardial-band isoenzyme(CK-MB) > lab upper limit of normal)

History of stroke or transient ischemic attack(TIA) within prior 6 months
Participating in investigational drug/device study that has not completed primary endpoint or interferes with study endpoints
Inability to comply with required trial antiplatelet regimen
Previous stent in target vessel unless it has been at least 9 months since stent placed and target lesion(s) is/are at least 15 mm from previous stent

Unprotected left main coronary artery disease

Primary Outcome Measures

Name	Time	Method
Target Lesion Failure(TLF)	9 month	Target Lesion Failure (TLF) at 9 months post-procedure defined as a composite measure of cardiac death, heart attack attributed to the target vessel (target vessel myocardial infarction), and ischemia-driven target lesion revascularization (TLR)

Secondary Outcome Measures

Name	Time	Method
Clinical Endpoints	5 Years	Success (device, lesion, procedure), major adverse cardiac events (MACE), target vessel failure (TVF), and stent thrombosis
Binary Angiographic Restenosis	Baseline and 9 month	Defined as =\> 50% in-stent diameter stenosis at the follow-up angiogram at 9 month. If an in-stent measurement is not available, the in-lesion diameter was used.
Percent Diameter Stenosis	Baseline and 9 month	The value calculated as 100 x (Reference Vessel Diameter(RVD) - Minimum luminal diameter(MLD))/ RVD using the mean values from orthogonal views (when possible) by quantitative coronary angiography(QCA).
Late Lumen Loss	Baseline and 9 months	Defined as the difference between the post-procedure immediate minimal lumen diameter (MLD) and the follow-up angiography MLD at 9 month.
MACE (Major Adverse Cardiac Event)	Baseline and 9 month	Death, myocardial infarction (Q-wave and non-Q-wave), emergent coronary bypass, or clinically-driven repeat target lesion revascularization by percutaneous surgical methods.
Minimum Luminal Diameter	9 month	The average of two orthogonal views(when possible) of narrowest point within the area of assessment-in lesion, in stent or in segment. minimal luminal diameter is visually estimated during angiography by the investigator; it is measured during quantitative coronary angiography by the Angiographic Core Laboratory.
