New Nanomed device: Replace Blood

ChrisPhoenix writes "Robert Freitas and I have published a paper on a rather aggressive nanomedical device that lines your blood vessels and replaces the blood. The paper covers benefits, requirements, installation, and more, with tons of medical information from Robert's amazing bank of knowledge. It's almost a megabyte and has 587 references.

Vasculoid: A Personal Nanomedical Appliance to Replace Human Blood.
Robert A. Freitas Jr. and Christopher J. Phoenix


The vasculoid is a single, complex, multisegmented nanotechnological medical robotic system capable of duplicating all essential thermal and biochemical transport functions of the blood, including circulation of respiratory gases, glucose, hormones, cytokines, waste products, and cellular components. This nanorobotic system, a very aggressive and physiologically intrusive macroscale nanomedical device comprised of ~500 trillion stored or active individual nanorobots, weighs ~2 kg and consumes from 30-200 watts of power in the basic human model, depending on activity level. The vasculoid system conforms to the shape of existing blood vessels and serves as a complete replacement for natural blood. This paper presents a preliminary theoretical scaling analysis including transport capacity, thermal conduction, control and biocompatibility considerations, along with a hypothetical installation scenario and a description of some useful optional equipment. A discussion of repair procedures and various applications of the personal vasculoid appliance is deferred to subsequent papers.

(I'll be doing a Friday night SIG on this at the upcoming Senior Associate Gathering.)"
