It eventually expanded into a full line of dialysis products for both hemodialysis (where a machine mimics kidney function by cleansing a patient's blood), and peritoneal dialysis (where the blood is cleansed by the injection of a dialytic solution into the peritoneum, the membrane that lines the walls of the abdomen, which eliminates the need for machine hook-up).
