Abstract
A system for augmenting a bone structure. A shape memory device includes a deflectable distal segment including temperature-dependent memory metal material. The shape memory device is slidably received within a guide cannula. The deflectable distal segment may include a substantially longitudinally straightened form, such as when subjected to a force from the guide cannula. The deflectable distal segment forms a first deflected shape having a first bend away from said straight longitudinal axis at a first elevated temperature greater than an initial temperature, and forms a second deflected shape having a second bend away from said straight longitudinal axis at a second elevated temperature greater than said first elevated temperature. The shape memory device may create voids within the bone structure with the deflectable distal segment at the first and/or second bends. Methods for positioning a shape memory device within a bone structure are also disclosed.
