Laser based metal deposition (LBMD) of antimicrobials to implant surfaces

A method for constructing a biomedical implant, the method comprising:

• forming a base structure from a metal material;
• and
• depositing a deposit onto the metal base structure-by Laser Based Metal Deposition (LBMD) in an inert gas atmosphere, wherein the deposit comprises an antimicrobial material and a first metal, wherein depositing the deposit comprises functionally graded layers, wherein the outermost layers possess the most potent antimicrobial properties.

A method for constructing a biomedical implant, the method comprising:

• forming a base structure from a biocompatible metal material;
• and
• depositing on the base structure a deposit to provide a surface other than a bone apposition surface or an articular surface via Laser Based Metal Deposition (LBMD) in an inert gas atmosphere, wherein depositing the deposit to provide the surface comprises positioning the surface to contact a non-articulating non-bony tissue adjacent to the implant.

A method for constructing a biomedical implant, the method comprising:

• forming a base structure from a metal material;
• and
• depositing on the base structure a deposit comprising an antimicrobial material and a first metal, wherein depositing the deposit is accomplished in an inert gas atmosphere, wherein the antimicrobial material comprises at least one of elemental silver, gold, platinum, palladium, iridium, copper, tin, antimony, bismuth, zinc, salts thereof, or intermetallics thereof.
