NTTF, located close to Bonn, Germany, is specialised in plasma coatings for medical devices and other high-tech coatings. The cardient® FMC coating is applied using a reactive gas phase plasma.
Cardient® FMC is a biocompatible and biofunctional coating especially developed for medical and biological applications.
The coating is an amorphous carbon coating with a quasi diamond-like structiure, particularly suitable for flexible polymer based medical implants. Implants that are coated with Cardient® FMC remain neutral towards cells and other living mircoorganisms. The implants can be populated excellently with somatic cells and are incorporated into the body quickly. At the same time, because of the low interdependency between surface and biomolecules, adhesion forces are reduced in a way that the population of biomolecules on implants in e.g. tube like structures of the body is decreased.
Materials that can be coated are polymer materials as well as highly temperature sensitive materials.
Application areas are catheters, stents and senors. One of the best known applications of cardient® FMC is the coating of urological stents. Here it creates a smooth, encrustation free surface on the implant and increases patient comfort.
