Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - NEVO™ Sirolimus-eluting Coronary Stent System
Treatment: Devices - Drug-eluting stent (TAXUS Liberte Paclitaxel-eluting Coronary Stent System)

Experimental: Investigational arm - Subjects randomized to treatment with the NEVO™ Sirolimus-eluting Coronary Stent System.

Active comparator: Control Arm - Subjects randomized to treatment with the TAXUS Liberte Paclitaxel-eluting Coronary Stent System.


Treatment: Devices: NEVO™ Sirolimus-eluting Coronary Stent System
Intervention will consist of percutaneous coronary intervention for treatment of a single coronary lesion using standard coronary intervention techniques. Intervention in this arm will include treatment with the Conor Cobalt Chromium Sirolimus-eluting Coronary Stent System. Subjects assigned to the IVUS sub-study population will undergo intravascular ultrasound evaluation immediately post-stenting.

Treatment: Devices: Drug-eluting stent (TAXUS Liberte Paclitaxel-eluting Coronary Stent System)

Intervention in this arm will include treatment with the TAXUS Liberte Paclitaxel-eluting Coronary Stent System.
