ABSTRACT:
Implantable medical devices fabricated at least in part of a polymer-bioceramic composite having bioceramic particles with radiopaque functional groups grafted to a surface of the bioceramic particles are disclosed. Implantable medical devices fabricated at least in part of a radiopaque material having bioceramic particles with polymer chains grafted onto a surface of the bioceramic particles, the radiopaque functional groups being chemically bonded to the grafted polymer chains, are disclosed.
