Coatings for use in artificial joints and other implanted medical devices. The coatings comprise a dual layer structure vapor deposited atop a medical grade substrate, such as cobalt chromium. The dual layer structure comprises a first ceramic layer vapor deposited atop at least a portion of the substrate and a second ceramic layer deposited atop the first ceramic layer. The first ceramic layer is formed of a material which has particularly good adhesion to the substrate, and the second ceramic layer from a material exhibiting particularly high hardness and good wear characteristics. The vapor deposition process is controlled so as to form a graded interface between the two ceramic layers to form a dual layer coating which resists delamination, adheres well to the substrate, and exhibits good wear characteristics in situ.

Implants may be coated with a biocompatible coating to improve the biocompatibility of the implant. The biocompatible coating may include a bone growth promoting compound. Such compounds include, but are not limited to, phospholipids, bone morphogenetic proteins, or combinations thereof. The bone growth promoting compound may enhance the rate of bone growth proximate to the implant and the integration of the implant into the surrounding bone.

A high-strength coating for dental and orthopedic implants utilizing hydroxyapatite (HAp) nanoparticles provides for a high level of osseointegration through a range of surface pore sizes in the micro- to nanoscale. Zinc oxide (ZnO) nanoparticles may be incorporated with the HAp nanoparticles to form a composite coating material, with ZnO providing infection resistance due to its inherent antimicrobial properties. A textured surface, consisting of “islands” of roughly square coating structures measuring about 250 μm on a side, with spacing of 50-100 μm therebetween, may further promote the osseointegration and antimicrobial properties of the implant coating.

Polymers of fluorinated monomers and acrylate and alkyl acrylates are disclosed which demonstrate improved performance as coatings for implantable devices. Such coatings may, for example, be used to release a bioactive agent from the medical device. One specific application lies in drug-eluting coatings for stents.

The present invention provides polymer brush constructs, for example, surfaces decorated with hyaluronan polymers, and methods of making the same. The constructs are useful as functional materials for numerous applications, e.g., as lubricants, implant coatings, bandages and other uses.

The invention belongs to the field of pharmaceutical coating technology, and specifically provides a coating technology for naltrexone implants, comprising the following steps: (1) dissolving polylactic acid in an organic solvent to form a coating solution, and placing it in a coating pool , standby; (2) Soak the naltrexone implant in the coating solution, wrap a layer of polylactic acid film on the surface of the implant; (3) hang and dry the naltrexone implant wrapped with the polylactic acid film . The coating pool is equipped with a liquid pool pipeline, which is evenly distributed with small holes and soaked in the coating liquid, so that the tablets can be evenly wrapped when passing through the liquid pool pipeline, and the method of hanging and drying is adopted to avoid the high viscosity. The coating fluid compromises the integrity of the coating due to the tablets sticking to each other or coming into contact with other objects. The present invention also provides the application of the above coating process in the preparation of naltrexone implants.

The invention relates to a coating for an implant component, a method for producing an implant component having said coating, and a use of said coating on an implant coating. The coating is intended for an implant component, in particular a spinal implant component, and is a TiNb coating which contains, in addition to an atom % proportion of Ti and an atom % proportion of Nb an atom % proportion of 5-30 atom % of Ag.
