  • Target lesion(s) must be located in a native coronary artery where target vessel(s) diameter is ≥ 2.0 mm and ≤ 3.3 mm and target lesion length is ≤ 28 mm, both assessed by on-line Quantitative Coronary Analysis (QCA).

Exclusion Criteria
  • Lesion(s) located within an arterial or saphenous vein graft or distal to a diseased (defined as vessel irregularity per angiogram and > 20% stenosed lesion by visual estimation) arterial or saphenous vein graft.
  • Lesion(s) involving a bifurcation with side branch vessel ≥ 2 mm in diameter and/or ostial lesion > 40% stenosed by visual estimation or side branch requiring predilatation.
  • Total occlusion (TIMI flow 0), prior to wire passing.

Primary Outcome Measures

Number of Participants With Ischemia Driven Target Lesion Revascularization (ID-TLR)0 to 3 years

Revascularization at the target lesion associated with any of the following:

* Positive functional ischemia study.

* Ischemic symptoms and angiographic minimal lumen diameter stenosis ≥ 50% by core laboratory quantitative coronary angiography (QCA).

* Revascularization of a target lesion with diameter stenosis ≥ 70% by core laboratory QCA without either ischemic symptoms or a positive functional study.

Minimum Vessel Area18 months
Maximum Lumen Area18 months
Maximum Plaque Area18 months
Number of Participants With Target Vessel Failure (TVF; Cardiac Death, Protocol MI, ID-TLR, ID-Non-TLR TVR)0 to 3 years

The composite endpoint composed of

* Cardiac death,

* Myocardial infarction (Q wave and Non-Q wave),

* Ischemia-driven target vessel revascularization by CABG or PCI.

Mean Lumen Area18 months
Minimum Plaque Area18 months
Number of Participants With Cardiac Death0 to 3 years

Any death due to proximate cardiac cause (e.g. MI, low-output failure, fatal arrhythmia), unwitnessed death and death of unknown cause, all procedure related deaths including those related to concomitant treatment.

Number of Participants With Ischemic Driven Non-target Lesion Target Vessel Revascularization (ID-Non-TL TVR)0 to 3 years
Number of Participants With Major Adverse Cardiac Events (MACE; Cardiac Death, Protocol MI, ID-TLR)0 to 3 years

Major adverse cardiac events (MACE) is defined as the composite of cardiac death, all myocardial infarction and ischemia-driven target lesion revascularization (ID-TLR).

Maximum Vessel Area18 months
Clinical Device SuccessOn day 0 (immediate post-index procedure)

Defined as successful delivery and deployment of the Clinical Investigation scaffold at the target lesion and successful withdrawal of the scaffold delivery system with attainment of final residual stenosis \< 50% by QCA (by visual estimation if QCA is unavailable). Standard pre-dilation catheters and post-dilatation catheters (if applicable) may be used. Bailout subjects will be included as device success only if the above criteria for clinical device success are met.

Clinical Procedure SuccessOn day 0 (immediate post-index procedure)

Defined as successful delivery and deployment of the Clinical Investigation scaffold at the target lesion and successful withdrawal of the scaffold delivery system with attainment of final residual stenosis of \< 50% by QCA (by visual estimation if QCA unavailable) and/or using any adjunctive device without the occurrence of ischemia driven major adverse cardiac event (MACE) during the hospital stay with a maximum of first seven days post index procedure. In a dual lesion setting both lesions must meet clinical procedure success.

Number of Participants With Scaffold Thrombosis (Early)0 to 30 days

Calculated Minimum Lumen Diameter18 months

The average of two orthogonal views (when possible) of the narrowest point within the area of assessment - treated lesion, treated site or treated segment. MLD is visually estimated during angiography by the Investigator; it is measured during QCA by the Angiographic Core Lab.

Calculated Diameter Stenosis18 months

The value calculated as 100 \* (1 - Minimum Lumen Diameter (MLD) / reference vessel diameter (RVD)) using the mean values from two orthogonal views (when possible) by quantitative coronary angiography (QCA).
