Abstract:
:This paper discussed issues of ethical assessment and moral concern associated with organ replacement and physical enhancement: research, allocation, organ donation, artificial organs, xenografts, biomaterials, and neuromaterials. While emphasizing the medical and moral benefits over associated risks, it calls for a better integration of moral assessment into technology assessment and for the establishment of a cross-cultural and interdisciplinary International Ethics Committee for Organ Replacement Therapy.
