Abstract
An implant device for stimulating osteogenesis and osseointegration comprises a hollow annular housing member, a pulsed current modulator, and a coil connected to the current modulator. The current modulator and at least a portion of the coil are mounted within the housing member. A frequency of the pulsed current is selected to generate an electromagnetic field of a predetermined flux density that penetrates, and propagates radially outwardly from, the housing member for a sufficiently large propagation distance to stimulate osteogenesis and osseointegration, by means of the generated electromagnetic field, of a bone region in which the implant device is implanted and which is disposed radially outwardly from the housing member.
