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 PFO Occluder:
Biocompatible
Non-corrosive
Non-allergic
More radiopaque
