Devices and methods for manufacturing devices for treating degenerated
and/or traumatized intervertebral discs are disclosed. Artificial discs
and components of discs may include an artificial nucleus and/or an
artificial annulus and may be comprised of shape memory materials
synthesized to achieve desired mechanical and physical properties. An
artificial nucleus and/or annulus according to the invention may comprise
a first and second reservoir and one or more fluids, wherein upon
application of a load upon the artificial nucleus and/or disc, the one or
more fluids enters said second reservoir from said first reservoir.
