Abstract
The invention relates to implantable bone-lengthening devices that are not placed intra-medullarily, but are placed extramedullarily, i.e., outside of the bones, but under the skin. The devices do not require exposed hardware (that leads to infection) or skin and muscle penetration from the pins (that cause pain), and produce minimal scarring from pin sites because the devices are placed under the skin of a patient using minimally invasive techniques. The devices may be designed with smooth contours to enable implantation using minimally invasive techniques. The devices may be actuated using an actuator that is externally or internally powered. In the case of external power, the devices may be powered remotely through high frequency transmission of power through the skin. Also included are bone-lengthening devices having fluid reservoirs and conduits for storing and delivering therapeutic fluids to treatment sites.
