  • Patient treated with immunosuppressives or for known immunodepressive or auto-immune pathologies
  • Patient receiving chronically anticoagulant therapy with an INR greater than 2.5

  • Patient with urinary or gastro-intestinal bleed in the preceding 6 months
  • Patient with other known serious medical illness or known history of substance abuse (alcohol, drugs) that might result in non-compliance to the investigational plan, or interfere with the results or diminish the life expectancy to less than a year.
  • Patient enrolled in an interventional study with another medical device or drug Angiographic exclusion criteria
  • Patient with in-stent restenosis located on the left main on the coronary by-pass
  • Patient with a lesion of the in-stent restenosis located in a bifurcation including a lateral branch of diameter > 1.5mm
