Claim:
1. A method of making a catheter, comprising the steps of: incorporating a conducting wire into a tubular braid comprising a multiplicity of supporting wires; covering the tubular braid with a sheath, wherein the tubular braid encloses an internal volume, and the sheath is opaque when illuminated external to the sheath rendering the conducting wire and the support wires invisible to a human eye observing the sheath, and transparent when illuminated interior to the sheath, rendering the conducting wire and support wires visible to the human eye through the sheath using a microscope; identifying a location of the conducting wire within the tubular braid by illuminating the tubular braid from the internal volume rendering the conducting wire and the supporting wires visible to the human eye through the sheath using a microscope; and attaching an electrode through the sheath to the conducting wire at the location while the tubular braid is illuminated from the internal volume.
