Abstract
A method for treating a medical implant uses plasma polymerization to apply a coating At least one treatment parameter is selected so that the reactive chemical groups of the coating are chemically modified to prevent an adsorption of interfering substances into the coating. An implant includes a plasma polymer coating that is biocompatible, and includes a antibiotically acting metal. The coating is free from aldehyde groups
Claims16
A method for treating a medical implant, the method comprising the steps of:
- placing the implant into a plasma reactor;
- and
