  • Apparatus for stimulating living tissue with means to control stimulating pulse time interval
    Patent number: 5144948
    Abstract: An apparatus for stimulating living tissue delivers a stimulating pulse with a predetermined stimulating pulse amplitude and a stimulating pulse duration. Each stimulating pulse is separated by a stimulating pulse time interval, which is controlled by a control device. Maintenance of the predetermined stimulating pulse amplitude is undertaken by continuous control of the stimulating pulse time interval by means of the control device, which increases the value of a predetermined minimum stimulating pulse time interval to a new value if the time period, from the time when the voltage across an output capacitor reaches the value of the stimulating pulse amplitude until the time when the stimulating pulse is delivered, is shorter than a safety time interval established by the control device.
