Older patients with end- stage kidney disease (ESKD) are at very high risk for functional impairment. Like more sizable dialysis machines, it was designed to filter the blood of people whose kidneys are no longer working. Minimal change disease (MCD), focal segmental glomerulosclerosis (FSGS), and Membranous nephropathy (MN), generate an enormous individual and societal financial burden, accounting for approximately 12% of prevalent end stage renal disease (ESRD) cases (2005) at an annual cost in the US of more than $3 billion. In the last few years, The Kidney Project successfully tested the hemofilter, which removes waste products and toxins from blood, and the bioreactor, which replicates other kidney functions, like the balance of electrolytes in blood, in separate experiments. Low fluid resistance and expanded surface area facilitated the efficiency of dialysis. Second, a bioreactor containing cultured kidney cells processes the ultrafiltrate and sends the sugars and salts back into the blood. The cells used in the device would be grown from the patients own cells and kept in a special compartment away from the persons bloodstream.
