What is the definition of an artificial organ?
An artificial organ is a human-made device implanted to replace or augment a natural function. It must operate without being tethered to stationary power supplies or external filters.

Chang and Poznanski made the first artificial RBC in 1968 to transport oxygen and carbon dioxide. This innovation emerged during the HIV-contaminated-donor blood crisis when interest grew for such devices.
Thomas Cervantes and colleagues built an artificial ear from sheep cartilage using a 3D printer. They adjusted models several times to match human curves and lines for patients with microtia.
Initial testing in humans frequently limits participation to those facing imminent death because they have often exhausted every other treatment possibility available to them. No human trial proceeds without prior validation through animal models to ensure safety.
Engineering an artificial trachea proved more challenging than originally thought between 2008 and 2014. Paolo Macchiarini worked at the Karolinska Institute until high-level management dismissed him in 2016 due to concerns about his methods.
