Abstract: A renal failure therapy system having an electrically floating fluid pathway is disclosed. The example system includes a dialyzer, a blood circuit in fluid communication with the dialyzer, and a dialysis fluid circuit in fluid communication with the dialyzer. The system also includes an electrically floating fluid pathway comprising at least a portion of the blood circuit and at least a portion of the dialysis fluid circuit. The only electrical path to ground is via used dialysis fluid traveling through the renal failure therapy system to earth ground. The disclosed system enables at least one electrical component in the at least a portion of the dialysis fluid circuit of the electrically floating fluid pathway to be electrically bypassed.
