High current pulser for transmural and field stimulation.
The determination of the requirements and the design of a constant current pulse generator with low internal resistance capable of providing the high currents required for transmural and field stimulation of biologic tissues are described. It is concluded that direct measurement of current flowing and voltage applied to electrodes is the best way of monitoring stimulus parameters.
