Abstract
Apparatus is disclosed for stabilizing the value of a parameter of the output pulses of a tissue stimulator, such as the magnitude of the current or the charge delivered in each output pulse to excite the cell membranes of the tissue to be stimulated. The apparatus measures the value of this parameter against target limits, and if either limit is exceeded, adjusts the value of a second parameter of the output pulses, such as voltage level or pulse width, to stabilize the value of the first parameter. The value of the first parameter may be measured by sampling thereof at a rate considerably less than the frequency of the output pulses, and the value of the second parameter then adjusted to bring the value of the first parameter within the target limits. Both current and charge stabilization modes of the pulse generating stimulator for efficient excitation of cell membranes of the selected tissue are described.
