ABSTRACT:
Provided is a prosthesis system for indirectly coupling a prosthesis to the skeletal structure of a person. The system includes a plurality of individual magnets and magnet sets attached to a prosthetic socket of a prosthetic device. The magnets may be permanent magnets or electromagnets. A second plurality of magnets is embedded within a residual limb of a person, mounted to or within a sub-dermal strut. In operation, the magnetic fields generated by the magnets of the prosthetic socket, which may be dynamic magnetic fields, interact with the magnetic fields generated by the magnets anchored beneath the skin of the person, to hold the prosthetic device in position during use. A power supply provides current to any electromagnets, and a controller alters any required magnetic fields based on input received from both load and position sensors in the sub-dermal strut.
