Clinical Inclusion Criteria:

* Subject must be at least 18 years of age.
* Subject (or legal guardian) understands the trial requirements and the treatment procedures and provides written informed consent before any trial-specific tests or procedures are performed.
* Subject is eligible for percutaneous coronary intervention (PCI).
* Subject is willing to comply with all protocol-required follow-up evaluation.
* Women of child-bearing potential must agree to use a reliable method of contraception from the time of screening through 12 months after the index procedure.

Angiographic Inclusion Criteria:

* Target lesion is a de novo lesion located in a native coronary artery
* Target lesion must have visually estimated stenosis \> 50% and \< 100% in symptomatic subjects (\>70% and \<100% in asymptomatic subjects) prior to lesion pre-dilation.
* Target lesion must be successfully pre-dilated.
* If a non-target lesion is treated, it must be treated first and must be deemed a success.

Clinical Exclusion Criteria:

* Subject has other serious medical illness (e.g. cancer, congestive heart failure) that may reduce life expectancy to less than 12 months.
* Subject has current problems with substance abuse (e.g. alcohol, cocaine, heroin, etc.).
* Subject has planned procedure that may cause non-compliance with the protocol or confound data interpretation.
* Subject is participating in another investigational drug or device clinical study that has not reached its primary endpoint.
* Subject intends to participate in another investigational drug or device clinical study within 12 months after the index procedure.
* Subject is a woman who is pregnant or nursing. A pregnancy test must be performed within 7 days prior to the index procedure, except for women who definitely do not have child-bearing potential.
* Subject has left ventricular ejection fraction known to be \< 30%.
* Subject had PCI or other coronary interventions within the last 30 days.
* Subject has planned PCI or CABG after the index procedure.
* Subject had STEMI or QWMI \<72h prior to the index procedure.
* Subject presents with NSTEMI and rising biomarkers, or ongoing chest pain or is hemodynamically unstable.
* Subject has cardiogenic shock (SBP \< 80 mmHg requiring inotropes, IABP or fluid support).
* Subject has history (within 6 months prior to the index procedure) of New York Heart Association (NYHA) class III or IV heart failure.
* Subject is considered not able to tolerate at least 30 seconds of coronary occlusion of the target lesion.
* Subject has known allergy to paclitaxel or other components of the used medical devices.
* Subject has known hypersensitivity or contraindication to contrast dye that in the opinion of the investigator cannot be adequately pre-medicated.
* Subject has intolerance to antiplatelet drugs, anticoagulants required for procedure.
* Subject has platelet count \< 100k/mm3 (risk of bleeding) or \> 700k/mm3.
* Subject with renal insufficiency (creatinine ≥2.0 mg/dl) or failure (dialysis dependent).

Angiographic Exclusion Criteria:

* In-stent restenosis.
* Target lesion is located within a saphenous vein or arterial graft.
* Target lesion is a total occlusion or has evidence of thrombus present in the target vessel.
* Target lesion is severely calcified by angiography or has \> 270° calcium arc on intravascular imaging or requires atherectomy.
* Subject has unprotected left main coronary artery disease (\>50% diameter stenosis) or three-vessel coronary disease requiring revascularization of all 3 vessels.
* Subject with planned treatment of lesion involving aortic ostial location.
