The purpose of this study is to determine the safety and feasibility of use in humans of the TAXUS Petal Paclitaxel-Eluting Bifurcation Coronary Stent System in the treatment of de novo lesions in native coronary arteries involving a major side branch. The TAXUS® Petal™ is an investigational device with an indication of improving coronary artery luminal diameter while maintaining side branch access in subjects with symptomatic ischemic disease due to discrete atherosclerotic bifurcation lesions
