  • Apparatus for producing a biomimetic coating on a medical implant
    Publication number: 20090220675
    Abstract: An apparatus for producing a biomimetic coating on an implantable article is provided. The apparatus includes an outer reactor for containing a biomimetic coating solution and an inner reactor arranged within the outer reactor. The inner reactor is smaller than the outer reactor so as to define a space between the inner and outer reactors. The apparatus also includes a pump system for circulating the biomimetic coating solution. The pump system is arranged to operate in the space between the inner and outer reactors. The inner reactor includes a flow control system that is selectively operable to control the flow of biomimetic coating solution between the outer and inner reactors.

  • Biological agent-containing ceramic coating and method
    Patent number: 7087086
    Abstract: The invention provides an implantable article, a method of preparing the same, and methods of modifying a ceramic-coated implantable article. The implantable article comprises a biocompatible substrate and a bioactive ceramic surface coating into which a biological agent is incorporated. The preparation and modification of an implantable article involve incubating a biocompatible substrate surface or pre-existing ceramic coating thereon with a composition comprising (i) a biological agent, (ii) calcium ions, (iii) phosphate ions, and (iv) a liquid carrier.
