Abstract
Controlling the transformation of the microstructure of shape memory material implants. A surgeon can use the inventive energy delivery device to control the rate of implant shape change, the extent of implant shape change, as well as the force exerted on the surrounding tissue. The invention allows for the fine control of force when fixating osteoporotic bone and rate of bone transport. This system models or measures the heating profile of the implant and provides the surgeon a method to control the extent of microstructure phase transformation so that the rate, force or extent of tissue movement can be controlled individually or together.
