Methods are provided for modifying a porous surface of an implantable medical device by subjecting the porous surface to a modified micro-arc oxidation process to improve the ability of the medical device to resist microbial growth, to improve the ability of the medical device to adsorb a bioactive agent or a therapeutic agent, and to improve tissue in-growth and tissue on-growth of the implantable medical device.

Methods of modifying the porous surface of implants

A method for bonding a porous tantalum structure to a substrate is provided. The method comprises providing a substrate comprising cobalt or a cobalt-chromium alloy; an interlayer consisting essentially of at least one of hafnium, manganese, niobium, palladium, zirconium, titanium, or alloys or combinations thereof; and a porous tantalum structure. Heat and pressure are applied to the substrate, the interlayer, and the porous tantalum structure to achieve solid-state diffusion between the substrate and the interlayer and between the interlayer and the porous tantalum structure.
