Abstract
Medical devices’ field is developing very fast and the polymers represent next to biocompatible alloys a priority to the research field. The duodenoscopes are intensely used for diagnosis and treatment of various pancreatic and biliary diseases, being in contact with all liquids from saliva, gastric juices and bile liquids. Next to the aggressive environment physical erosion occurs. Using the optical microscopy the superficial polymer coating was analyzed. The deterioration of the coating is increasing the risk of infections and biofilms.
