Polymeric Coatings in Medical Devices

When assessing how well an implant integrates with the human body, the surface of the implant is crucial. Proper coatings are helpful and frequently necessary for the implant to be accepted and function well. Medical device coatings can lessen discomfort and inflammation while also improving implant placement by reducing friction within the body. It can increase biocompatibility by preventing the scarring that surrounds devices implanted, lowering the risk of infection associated with the device, and promoting the development of tissues that aid in the healing process. Coating a gadget that is inserted into the body is an extremely important procedure. The coating needs to be consistent, covering the entire surface, which is frequently made up of a complicated structure and prevents the structure from being altered. Many technologies have been developed recently to give medical devices a thin coating. These include surface polymerization, which creates a film from a monomer vapor; spray coating, which deposits a fine film; physical vapor deposition (PVD), which transfers a surface film from a solid source; and inkjet coating, which deposits a coating by impinging tiny droplets. The most significant methods and uses of thin coatings on medical devices are covered in this chapter.
