摘要：
A device and method of correcting a spinal defect in a patient employs the use of shape memory material in a spinal correction device. The shape memory material may be transitioned between a flexible martensitic state to allow shaping of the spinal correction device and a rigid austenitic state to apply corrective forces to the spine. The shape memory material may be transitioned to the flexible martensitic by applying a coolant, such as cold gas, directly or indirectly to the shape memory material to transfer heat away from the material. The cooling device and method may allow for in-vivo shaping of the spinal correction device while inserted in the body and attached to bone anchors by cooling the spinal correction device after insertion.
