Medical utensils, especially exploring or guiding threads, called guide wires, are coated with a hydrophilic, biocompatible, friction reducing, protein-based coating by application of a protein-containing solution, which has been pretreated by ebullition and addition of auxiliary substances, preferably tanning and sodium chloride, whereupon the coating undergoes a thermal treatment for partial denaturation of the proteins, whereby a thin coating with a good attachment is obtained, which will not harm the patient in case it should be scraped-off during use of the utensils. |
