Artificial Kidney Technology
The MIT Technology Review looks at the technology base that will - in years ahead - lead to entirely artificial organs to replace failing or age-damaged kidneys: "Next-generation membranes, now being engineered, will have more than 100,000 pores or slits per square millimeter and provide more than 10 times the flow. An implanted device carrying several hundred square centimeters of this next-generation membrane [should provide] about one-third of normal kidney function. ... it remains to be seen if the [researchers] can squeeze their filtration systems into a package small and robust enough for implantation. ... their goal to more precisely emulate the function of the kidney is right on - and a welcome alternative to the incremental improvements in more conventional technologies that have dominated dialysis developments for the past 20 years."
