Abstract:
A stimulation apparatus for providing pulsed electrical outputs to stimulate a portion of a body of a patient, the apparatus comprising:a common pulse generator that generates a control pulse, the control pulse being pulsed by the common pulse generator at a master frequency; a pulse pair generator to generate dual trigger pulses in respective channels, the trigger pulses being generated in response to the pulse pair generator receiving the control pulse at the master frequency, each of the trigger pulses including a trio of pulses; a channel control that controls which channel will be active; a set of dual independent voltage pumps that are controlled by the channel control, each of the respective voltage pumps operating on one of the channels, each of the voltage pumps adjustably generating output pulses in response to a corresponding trigger pulse based on the control of the channel control; a set of active electrodes that each receive output pulses from a respective one of the voltage pumps; and a single ground electrode to receive at least a portion of the output pulses from at least one of the active electrodes.
