1. An implant system, comprising:

  • an expandable implant including an expandable implant body that is made from an expandable material, the expandable material including a polymer matrix and an expandable gas source contained within at least a portion of the polymer matrix;

    wherein the polymer matrix transitions when heated from a first state in which the polymer matrix resists expansion to a second state in which the polymer matrix can be expanded thereby allowing the expandable gas source to expand inside the polymer matrix causing the implant body to expand from a first stable volume to a second expanded volume that is greater than the first stable volume.
