A genitronic replicator was a device designed by Doctor Toby Russel in the mid-24th century. Using genitronics, the device could scan a person's DNA and any damaged organs that they had, and then replicate a new, healthy replacement organ. Doctor Simon Tarses would later refine the procedure, by using it in combination with nano-technology. He would use it to help regenerate the damaged portions of Lieutenant Ro Laren's spinal cord when it was severed by Taran'atar's attack. (DS9 novel: Warpath)
