  • Publication number: 20080241353
    Abstract: The invention relates to a biomimetic process for coating a substrate, particularly a medical device, with a biomimetic composition, which comprises: d) producing batchwise in a closed system an acidified biomimetic composition comprising a saline aqueous mixture containing calcium-, magnesium-, phosphate-, bicarbonate ions and a bioactive substance, e) contacting the substrate with said biomimetic composition and f) storing the biomimetic composition in contact with the substrate and allowing a gradual increase of the pH to occur and to cause precipitation of salts and co-precipitation of the bioactive substance on said substrate and to obtain a coated substrate.

  • Patent number: 6692790
    Abstract: The invention relates to a method for providing a proteinaceous coating on a medical implant, comprising the steps of: submersing the implant in a first aqueous solution comprising a protein and magnesium, calcium and phosphate ions through which a gaseous weak acid is passed; degassing the solution; allowing a coating to precipitate onto the implant; submersing the coated implant in a second solution to redissolve the magnesium, calcium and phosphate ions and to obtain the proteinaceous coating.
