Disclosed are medical prosthetic device or medical implants which exhibit improved biocompatibility. The devices or implants include a metal material, e.g., titanium, in which the metal surfaces are coated with a corresponding hydride material that contains one or more biomolecule substance. The biomolecule substance may contain one or more biologically active molecules, e.g., bio-adhesives, biopolymers, blood proteins, enzymes, extracellular matrix proteins, extracellular matrix biomolecules, growth factors and hormones, peptide hormones, deoxyribonucleic acids, ribonucleic acids, receptors, inhibitors, drugs, biologically active anions and cations; vitamins; adenosine monophosphate (AMP), adenosine diphosphate (ADP) or adenosine triphosphate (ATP), marker biomolecules, amino acids, fatty acids, nucleotides (RNA and DNA bases), or sugars.
A method for preparing a medical prosthetic device or medical implant, said method comprising:
The method as claimed in 1, wherein the electrolysis treatment is carried out at a current density between about 0.1 mA per cm2 and 1A per cm2.
The method as claimed in 1, wherein the electrolysis treatment is carried out at a current density of about 1 mA/cm2.
Dependencies are inferred from the claim text.
