Antithrombogenic Coatings
- Introduction
- Antithrombogenic coatings reduce thrombus formation on the device surface and are not adjusted on a patient-specific basis.
- Advantages
- Safety
- Ease of use
- Reduce risks during drug injection procedure
- Visual inspection of ECMO tubes coated with antithrombogenic coating
- Visual inspection of tube after in vitro circulation for 48hr.
