Abstract
The present application relates to a new stimulation design which can be utilized to treat neurological conditions. The stimulation system produces a burst mode stimulation which alters the neuronal activity of the predetermined site, thereby treating the neurological condition or disorder. The burst stimulus comprises a plurality of groups of spike pulses having a maximum inter-spike interval of 100 milliseconds. The burst stimulus is separated by a substantially quiescent period of time between the plurality of groups of spike pulses. This inter-group interval may comprise a minimum of 5 seconds.
Claims24
A method of stimulating nerve tissue of a patient to treat a neurological disorder using an implantable pulse generator, the method comprising:
- generating, by the implantable pulse generator, a burst stimulus that comprises a plurality of groups of spike pulses in which after an initial spike pulse having an initial potential each spike pulse within the group occurs during a plateau potential before the entire group of spike pulses repolarizes to the initial potential and is followed by a substantially quiescent period between the plurality of groups, wherein each spike within each group is separated by a maximum inter-spike interval and each group of spikes is separated by a minimum inter-group interval, wherein the maximum inter-spike interval is 5 milliseconds and the minimum inter-group interval is 20 milliseconds;
- providing the burst stimulus from the implantable pulse generator to a medical lead;
- and
- applying the burst stimulus to nerve tissue of the patient via one or several electrodes of the medical lead.
