Brief Summary:
TAXUS ATLAS is a global, multi-center, single-arm, non-inferiority trial comparing results from patients treated with the TAXUS Liberté 38 mm stent to an historical TAXUS Express control. The control group is a case-matched, blended, long lesion subset population of TAXUS Express patients from the TAXUS IV and TAXUS V de novo clinical trials. The objective of the study is to evaluate clinical outcomes of TAXUS Liberté-SR 38 mm stent in de novo lesions and to assess the non-inferiority of TAXUS Liberté versus TAXUS Express. The TAXUS Liberté-SR stent is hypothesized to have comparable safety and efficacy to the TAXUS Express stent.

  7. Willing to comply with all specified follow-up evaluations

Angiographic Inclusion Criteria:

  1. Only one lesion (target lesion) may be treated with the study stent.However, one additional lesion in a non-target vessel may be treated during the index procedure with a commercially available bare metal stent, heparin-coated stent or TAXUS Express stent.
  2. Successful predilation is mandatory for entry into study
  3. Target lesion located within a single native coronary artery
  4. Target lesion enrolled for treatment may be composed of multiple lesions (not more than 10mm between diseased segments) but must be completely covered by one study stent.
  5. Cumulative target lesion length is greater than or equal to 26 mm and less than or equal to 34 mm (visual estimate)
  6. Target lesion RVD is greater than or equal to 2.7 mm and less than or equal to 4.0 mm (visual estimate)

General Exclusion Criteria:

  1. Known hypersensitivity to paclitaxel
  2. Any previous, concurrent or planned treatment with a non-study anti-restenotic drug-coated or drug-eluting coronary stent.
