1. An implantable vaso-occlusive device, comprising:
a vaso-occlusive structure comprising a zirconium or zirconium alloy and a metallic material that is electrochemically dissimilar to the zirconium or zirconium alloy, wherein the zirconium or zirconium alloy or the metallic material are in contact with, or otherwise in close proximity to, each other, such that the vaso-occlusive structure undergoes galvanic corrosion when both of the zirconium or zirconium alloy and the metallic material are exposed to blood and/or other body fluid, thereby creating a corrosive product comprising zirconia after the vaso-occlusive device has been implanted in a vasculature.
