In vivo Data

 

OCT-post OCT-3M 

OCT-9M OCT-12M OCT-18M

 

Effective scaffolding followed by programmed dismantling at around 3 months to enable positive remodeling and safe complete resorption within 24 months

 

Key facts :

  • Prevent acute and chronic recoil
  • Transient and effective scaffolding
  • Allow the artery to remodel after the scaffold dismantles
  • Black boxes turning white is driven by the polymer hydration, essential for hydrolysis
