Organ transplantation has been one of the miracles of modern-day medicine but, in addition to presenting enormous technical and clinical challenges, it throws up major ethical and legal issues principally from the perspective of the donor. Evolving capabilities in the spheres of both organ and tissue transplantation, coupled with rapidly-escalating demand, assert consistent and critical pressure on our ethical and legal principles and frameworks, including the expansion of the potential donor pool beyond the conventional categories of donor. This volume brings together seminal papers analyzing such matters in the context of an ever-increasingly important area of clinical practice.
