Claim 17:
18. An implantable medical device, comprising:
a first metallic planar disc having a nanoscale through-porous structure, the first nanoscale through-porous structure having a surface treatment pattern configured to increase a surface area of exposure of the first nanoscale through-porous structure to an exterior of the implantable medical device;
a second metallic planar disc having a nanoscale through porous structure opposite and symmetric with the first metallic planar disc; and
the first metallic planar disc and the planar disc portion being engaged to an implantable medical grade metal spacer ring, the spacer ring including:
a first bezel on a first side of the spacer ring sized to receive the first metallic planar disc and a second bezel on a second side of the spacer ring sized to receive the second metallic planar disc;
an aperture, and when the first metallic planar disc and the second metallic planar disc are engaged to the spacer ring, they are in fluid communication with each other through the aperture; and
a port extending away from the spacer ring and a fluid delivery tube coupled to the port, the port being in fluid communication with the first metallic planar disc and the second metallic planar disc.
