Publication number: 20190192740Abstract: An implant is provided having an antibiotic coating that is inexpensive and easy to manufacture. The antibiotic coating adheres well and in stable manner to the surface of the implant, can be degraded by the body without forming toxic products, prevents the crystallization of the antibiotics in the coating, and ensures a high immediate locally-effective antibiotic concentration at the implant site. A coating solution useful for making the implant and a method for the manufacture of the implant are also described.Type: ApplicationFiled: February 22, 2019Publication date: June 27, 2019Inventors: Sebastian VOGT, Hubert BÜCHNER, Klaus-Dieter KÜHN
