Primary Outcome Measures :
  1. late lumen loss rate by Quantative/ Qualtative Cornary Angiographia [ Time Frame: 6 month ]
  2. total percentage of strut coverage by Optical Coherence Tomography analysis [ Time Frame: 6 month ]
  3. Primary safety endpoint is the occurrence of adverse events associated with the Investigational and comparator devices. [ Time Frame: 6 month ]
  4. binary restenosis rate by Quantative/ Qualtative Cornary Angiographia [ Time Frame: 6 month ]

Exclusion Criteria:

  1. Known allergy or sensitivity to cobalt chromium (CoCr) alloy or its components.
  2. Known sensitivity or allergy to aspirin, radiographic contract agents (that cannot be pre-treated adequately).
  3. Patients unable to tolerate anticoagulant therapy or antiplatelet therapy.
  4. History of bleeding or known coagulopathy.
  5. Patients with thrombocytopenia and or neutropenia.

  11. Disabling stroke within previous 30 days.
  12. Patients currently enrolled in another Investigational device or drug study.
  13. Previous enrollment in this study.
  14. Women who are currently pregnant. (A negative pregnancy test for female subjects of child bearing potential is required within 24 hours of procedure.)
  15. Known or suspected active systemic infection.
  16. Evidence of severe or uncontrolled systemic diseases, including chronic renal insufficiency, or any condition which in the Investigator's opinion makes it undesirable for the patient to participate in the trial or which would jeopardize compliance with the protocol.
