A Study of the TAXUS Liberté Stent for the Treatment of de Novo Coronary Artery Lesions in Small Vessels

TAXUS ATLAS Small Vessel is a global, multi-center, single-arm, trial of patients with coronary arteries less than 2.5 mm in diameter who are treated with the TAXUS Liberté stent versus an historical TAXUS Express control derived from a subset of lesion-matched TAXUS V patients treated with a 2.25 mm stent. The objective of the study is to evaluate clinical and angiographic outcomes of TAXUS Liberté-SR 2.25 mm stent in de novo lesions. The hypothesis is that the TAXUS Liberté-SR stent has non-inferior safety and efficacy to the TAXUS Express-SR stent in the treatment of de novo lesions in small coronary vessels.
