Tantalum. A nurse holding a short segment of fine tantalum wire. This is implanted to help the regeneration of nerves. The implant forms a structure bridging the two ends of a damaged nerve, allowing new cells to grow to join to effect a repair. It is most used in facial surgery. Photographed at the Second Moscow Medical College in Russia in 1976.
