Abstract
The present apparatus is especially constructed for osteotomic purposes. Bone extension means are movably supported in an elongated, slender housing. The extension means include an extension member movably extending out of said housing. Drive means are supported in the housing and operatively connected to the extension means. The drive means are energized through a source of power which may be either located in the housing itself, or it may be an external power source, such as a magnetic field. The power source is operatively connected to said drive means. Control means are supported in said housing to operate the drive means through said power source for moving the extension member. Sealing means seal the housing so as to provide an implantable structural unit.
