Biomedical electronics-update

Lusted\´s brief paper, "Biomedical electronics: 2012 A.D." [1961], remains a shrewd prediction. Lusted focuses on three aspects of organ replacement and then on genetics. The physiological control systems for human organs have proved to be considerably more complex than the simple "feedback loop" of 1961. In his prediction, Lusted quite reasonably names "heart, kidneys, stomach, and even liver" as logical candidates for successful replacement by 2012 with artificial devices. Of course, none of the devices is yet available, nor in sight. The author of the present paper reexamines artificial organs and control, genetics and the evolution of biomedical electronics.
