Abstract
The present invention relates to a non-invasive expandable implant utilizing energy from an epiphyseal growth plate of a human long bone to expand the implant. A bone replacement section includes a housing, an expansion shaft, a connection system, and an implant member. An anchoring member is secured to the second bone portion and spaced from the implant member. The expansion shaft is configured to translate a first distance between the housing and the first bone member. Growth of the bone causes an increase of a second distance between an implant portion and the anchoring member. The increase of the second distance causes the anchoring member to exert a force on a connection system causing an increase of the first distance, thus expanding the implant.
