Background: The wearable artificial kidney (WAK) has been a holy grail in kidney failure for
decades. Described herein are the breakthroughs that made possible the creation of the
WAK V1. 0 and its advanced versions V 1.1 and 1.2. Design: The battery-powered WAK
pump has a double channel pulsatile counter phase flow. This study clarifies the role of
pulsatile blood and dialysate flow, a high-flux membrane with a larger surface area, and the
optimization of the dialysate pH. Flows and clearances from the WAK pump were compared …
