title: An inexpensive bipolar stimulator.
abstract: The design of a pulse generator for electrical transmural stimulation is described. The device produces pulses of alternating polarity with amplitudes continuously variable up to 120 V and output currents limited to 6 mA. Pulse widths may be varied from 1 to 5 ms with repetition rates from 1.7 to 40 pulses per sec. A gate signal may be applied to inhibit output so that bursts of pulses may be generated.
