the index procedure, or lactating

20. Life expectancy of less than 24 months due to other medical condition

21. Co-morbid condition(s) that could limit the patient's ability to participate in the
study, compliance with follow-up requirements or impact the scientific integrity of
the study

22. Currently participating in another investigational drug or device study that has not
completed the primary endpoint or that clinically interferes with the endpoints of
this study

Angiographic

1. Unprotected and protected left main coronary artery disease (patient with protected
left main disease can be enrolled ONLY if the target lesion is in the RCA)

2. Target lesion is ostial in location (within 3.0 mm of vessel origin)

3. Target lesion and/or target vessel proximal to the target lesion is moderately or
severely calcified by visual estimate

4. Target lesion and/or target vessel proximal to the target lesion is tortuous

5. Target lesion is located within or distal to a >60 degree bend in the vessel

6. Target lesion involves a bifurcation with a side branch vessel >1.5 mm (visual
estimate)

7. Target lesion is totally occluded (TIMI flow <1), either at baseline or predilation

8. Angiographic presence of probable or definite thrombus

9. Pre-treatment of teh target vessel at the index procedure is not allowed with any
device except for predilation with balloon angioplasty or cutting balloon

10. A previously treated lesion within the target vessel:

- <15mm from the target lesion (visual estimate)

- Performed </= 6 months from index procedure

- >30% residual stenosis after previous treatment

Summary
Brief summary
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.
