Platinum nanocoating
Platinum nanocoating
- Ultrathin layer of Platinum atoms using nanofusion technology is coated on the Nitinol wire by a process called plasma deposition
- Platinum nanocoating makes the Cocoon Occluders inert, biocompatible, non-corrosive and non-allergic and also enhances radiopacity
Platinum nanocoating makes the Cocoon Septal Occluder:
Biocompatible
Non-corrosive
Non-allergic
More radiopaque
Optimal Sealing of Defects
The waist of Cocoon Septal Occluder has adequate sealing strength at the level of the discs: Up to 100% immediate closure rates1, 2
