A force, displacement, and rate controlled shape memory material implant. The rate of implant shape change as well as the force exerted on the surrounding tissue of the implant can be controlled by the surgeon and the extent of movement is controlled in circumstances where the bone element is free to move. The invention allows for the first time the fine control of force when fixating osteoporotic bone and rate of bone transport when working near the spinal cord. This heating profile of the implant provides the surgeon to control the extent of microstructure phase transformation so that the rate, force or extent of tissue movement can be controlled individually or together. |
