Description of intervention(s) / exposure
The study will randomize 230 patients with de novo lesions in native coronary arteries with a reference diameter of 2.0 – 2.75 mm. The 3 treatment arms include the CardioMind sirolimus-eluting stent, the CardioMind bare metal stent, and the Medtronic Micro-Driver bare metal stent. Clinical follow-up will occur at 30 days, 8, 12 and 24 months. Telephone follow-up will occur at 6 months and years 3-5. Data will be compared among treatment groups.

Summary
Brief summary
The study will enroll 230 patients in a randomized evaluation of a new stent delivery system developed for use in small coronary arteries. The study device is designed with a low profile, maneuverable delivery system to reach small, distal lesions. This study is designed to show that the new stents are safe and effective when compared to the comparator, commercially-available stent. Follow-up will occur at 30 days, 6, 8, and 12 month intervals for the first year, then annually for the next four years.
