Claim 13:
14. An apparatus for spinal delivery of a device, the apparatus comprising:
a spinal needle comprising a hollow needle shaft having a substantially constant cross-sectional area, wherein the spinal needle is sized to percutaneously inject the device into the spine of a human subject; and, a device at least partially contained within the hollow shaft of the spinal needle, the device comprising:
an implantable structure defining a conduit therein connecting a first end to a second end;
a flow controller positioned within the implantable structure in an orientation that allows fluid to flow through the conduit from the first end to the second end;
a first expansion apparatus positioned at a first end of the implantable structure, wherein the first expansion apparatus, when removed from the hollow needle shaft, is expandable into a configuration larger than the cross-sectional area of the hollow needle shaft; and
a second expansion apparatus positioned at a second end of the implantable structure, wherein the second expansion apparatus, when removed from the hollow needle shaft, is expandable into a configuration larger than the cross-sectional area of the hollow needle shaft.
