Abstract
The implant of the present invention is composed of a core body having an outer surface of a composition of at least two dissimilar biocompatible metal components or metal alloy components in intimate contact with one another with said dissimilar metals or metal alloy components each having an EMF sufficient to form a potential difference of at least 25 mV and preferably over 100 mV.
Claims8
An implant for stimulating and accelerating bone formation at the interface between the implant and bone comprising a core having at least two different surface compositions with the first and second surface compositions represented by a composite of multiple metal particles with the particles of the first surface composition being so small in size that a multiple number of particles exist in each square mm of surface area of said core and with said particles in said first surface composition having a geometry with an average length of less than 100 microns such that an EMF potential difference of at least 25 mv will be generated between said particles of said first and second composition in each square mm of the core surface area.
