Abstract:
1. A neurostimulation device capable of being placed between a stimulation mode for delivery of a series of stimulation pulses and a standby mode, comprising: a plurality of electrical terminals configured for being respectively coupled to a plurality of stimulation electrodes; a first solid-state switching device coupled to a first one of the electrical terminals, wherein the first solid-state switching device has a closed state in which current can flow through the first solid-state switching device and first and second open states in which flow of current through the first solid-state switching device is prevented if the current is below a threshold; a variable power source coupled to the first switching device; and a controller configured for placing the neurostimulation device in the stimulation mode for delivering the series of stimulation pulses and placing the neurostimulation device in the standby mode when not delivering the series of stimulation pulses, wherein the controller is further configured for, when the neurostimulation device is in the standby mode, prompting the variable power source to selectively output a relatively low voltage to place the first switching device into a first open state and a relatively high voltage to place the first switching device into a second open state and, when the neurostimulation device is in the stimulation mode for delivering the series of stimulation pulses, prompting the variable power source to output the relatively high voltage to place the first switching device into the second open state during conveyance of each of the pulses in the series of stimulation pulses and into the closed state between the pulses of the series.
