failure (i.e., New York Heart Association (NYHA) class IV) at the time of the index procedure Subject is participating in another investigational drug or device clinical trial that has not reached its primary endpoint Subject intends to participate in another investigational drug or device clinical trial within 12 months after the index procedure Subject with known intention to procreate within 12 months after the index procedure (women of child-bearing potential who are sexually active must agree to use a reliable method of contraception from the time of screening through 12 months after the index procedure) Subject is a woman who is pregnant or nursing Angiographic Exclusion Criteria (visual estimate) Subject has more than 1 target lesion, or more than 1 target lesion and 1 non-target lesion, which will be treated during the index procedure Note: Multiple focal stenoses will be considered as a single lesion if they can be completely covered with 1 study stent Treatment of lesions in more than 2 major epicardial vessels Note: 1 target lesion in the target vessel and 1 non-target lesion in non-target vessel is allowed Subject has unprotected left main coronary artery disease (>50% diameter stenosis) Subject has been treated with any type of PCI (i.e., balloon angioplasty, stent, cutting balloon atherectomy) within 24 hours prior to the index procedure Thrombus, or possible thrombus, present in the target vessel (by visual estimate) Target lesion meets any of the following criteria: Treatment of a single lesion with more than 1 stent Left main location Lesion is located within 3 mm of the origin of the left anterior descending (LAD) coronary artery or left circumflex (LCx) coronary artery by visual estimate Lesion is located within a saphenous vein graft or an arterial graft Lesion will be accessed via a saphenous vein graft or arterial graft Lesion with a TIMI flow 0 (total occlusion) or TIMI flow 1 prior to guide wire crossing Lesion treated during the index procedure that involves a complex bifurcation (e.g., bifurcation lesion requiring treatment with more than 1 stent) Lesion is restenotic from a previous stent implantation or study stent would overlap with a previous stent Non-target lesion meets any of the following criteria: Located within the target vessel Left main location Lesion is located within a saphenous vein graft or an arterial graft Lesion with a TIMI flow 0 (total occlusion) or TIMI flow 1 prior to guide wire crossing Lesion treated during the index procedure that involves a complex bifurcation (e.g., bifurcation lesion requiring treatment with more than 1 stent) Requires additional unplanned stents (treatment of the non-target lesion with more than one stent is permitted as long as the stents are initially planned) Treatment not deemed an angiographic success Note: Angiographic success is a mean lesion diameter stenosis < 50% (< 30% for stents) in 2 near-orthogonal projections with TIMI 3 flow, as visually assessed by the physician, without the occurrence of prolonged chest pain or ECG changes consistent with MI.
