The margins of these devices were clearly discernible and materially circumscribed, allowing the distinction between the corporeality of the human body and the “machine” to remain both ontologically and materially secure. This dualism has performed some important work for human rights theorists, regulators, and policy makers, enabling each to imagine they can establish where the human ends and the other begins. New regenerative products such as Infuse™ and Amplify™ subsist, as animal derived scaffolds seeded with growth hormone implanted within a prosthetic device. They are much more materially complex, and their identities thus remain open to contestation. Following Lochlann Jain’s 2006 work, I thus attend closely to their social lives, particularly the stories that are told about them and how these are employed to construct understandings of what kind of a phenomenon they are: systemic drug, biologic, or combinatorial medical device. The significance of this classificatory project is revealed in the final section of this paper, which explores how these stories shape understandings of “product failure,” liability, and causation when such products overflow their material and ontological categorization and their recipients become disturbingly “more than human.”.The author would like to thank her colleagues for the invitation to attend the very stimulating conference New Technologies and Developments in the Biosciences and the New Frontiers of Human Rights held at Durham University and funded by the Institute for Advanced Studies at Durham University, SLSA, Durham Law School and the Anthropology Department at Durham, which gave rise to this paper. She would also like to thank Noa Vaisman for her intellectual input and patience and the reviewers for their generous comments and assistance in refining this paper.26enPublisher Copyright: © The Author(s) 2017.Alternative life formsFuturesGovernanceLawMarkets/economiesMedtronicPoliticsPowerRegenerative medicine2017-10-1510.1177/016224391773517985048518955
