Abstract
A current limiter for a defibrillation pulse is powered by the defibrillation pulse and switches the current delivery path open and closed when an excessive current condition exists. The excessive current condition is sensed by a sense resistor of the current limiter. The controlled current is delivered by an inductor which delivers a current which varies in a range about a predetermined current level during excessive current conditions. The current limiter dissipates little energy of the defibrillation pulse so that most of the energy produced by the defibrillator is delivered to the patient.
