Abstract

A method of reducing leakage current from a patient to a ground potential through an applied part of a medical device includes defining a maximum permissible leakage current Afrom the patient to the ground potential when the patient is energized to an electric potential V and supplying the medical device with water having a resistivity value ρ through a fluid line having a length L and an inner diameter ID. The value of L and ID is selected to cause the fluid conduit filled with water of resistivity ρ to have a resistance of R high enough to maintain the leakage current from the patient to the ground potential below A.
