12 Month All Death Rate	Participants will be followed for the duration of hospital stay, an expected average of 1 day, through 12 months
12 Month Cardiac Death or MI Rate	Participants will be followed for the duration of hospital stay, an expected average of 1 day, through 12 months
12 Month All Death or MI Rate	Participants will be followed for the duration of hospital stay, an expected average of 1 day, through 12 months
12 Month All Death/MI/TVR Rate	Participants will be followed for the duration of hospital stay, an expected average of 1 day, through 12 months
12 Month Stent Thrombosis Rate (Definite or Probable by Academic Research Consortium [ARC] Definitions)	Participants will be followed for the duration of hospital stay, an expected average of 1 day, through 12 months
Periprocedural Endpoints: Technical Success Rate	Participants will be followed for the duration of hospital stay, an expected average of 1 day	Technical success: successful delivery and deployment of the study stent to the target vessel, without balloon rupture or embolization. Summarized per attempted study stent.
Clinical Procedural Success Rate	Participants will be followed for the duration of hospital stay, an expected average of 1 day	Clinical Procedural Success: lesion diameter stenosis \< 30% in 2 near-orthogonal projections with TIMI 3 flow, as visually assessed by the physician, without the occurrence of in-hospital MI, TVR, or cardiac death. Summarized per patient.
