An extraordinary gamut of medical and surgical therapies could be considered "halfway technologies," addressing mere symptoms or manifestations of disease, rather than the underlying pathogenesis. When a "halfway" technology is also lifesaving, its value cannot be underestimated by the individual patient. The example of organ transplantation explored in this column represents a halfway technology. It does not treat the underlying disease itself, but reflects the absolute failure of all efforts at medical and conservative therapy and is a last ditch, gerry-rigged lifesaving solution. And what about "quarter technologies"--the bridge to transplant devices--designed to get the patient halfway to the final halfway procedure?
