Abstract
Systems and methods for active charge-balancing for high frequency neural stimulation are disclosed. One illustrative method described herein includes: applying, through a pair of electrodes electrically coupled to a bundle of nerve fibers during a stimulation phase of a neural stimulation procedure, a first current to the bundle of nerve fibers; applying, through the pair of electrodes during a recovery phase of the neural stimulation procedure, a second current to the bundle of nerve fibers, the first current and the second current having opposite polarities; determining sampled voltages between the pair of electrodes during the stimulation phase, during the recovery phase, or between the stimulation phase and the recovery phase; determining a charge buildup in the bundle of nerve fibers based on the sampled voltages; applying, through the pair of electrodes during the stimulation phase or during the recovery phase, a delta current to the bundle of nerves based on the sampled voltages to minimize the charge build up.
