Brief summary

The purpose of this study is to assess the safety and effectiveness of the SYNERGY Everolimus-Eluting Platinum Chromium Coronary Stent System for the treatment of subjects with atherosclerotic lesion(s) ≤ 34 mm in length (by visual estimate) in native coronary arteries ≥2.25 mm to ≤4.0 mm in diameter (by visual estimate).

Detailed description

A concurrent, non-randomized, single-arm, pharmacokinetic (PK) substudy and a consecutive, non-randomized, single-arm, Diabetes substudy will also enroll under the EVOLVE II protocol.
