For analyzing technologies which are intended to reproduce normal physiological functions, the appropriate questions to ask include:
– What aspects of the native organ function are replicated, and which are not? (this should include a quantitative analysis of function, for example filtration rates in artificial kidney compared to natural kidney)
– What are the limitations of the device/implant?
– What could be done to improve the performance to match the native organ?
– How does the device/implant interfere with normal physiology?
