Stimulation design for neuromodulation
First Claim
1. 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 with a substantially quiescent period between each group in the plurality of groups, wherein (i) each group of spikes begins and ends at a reference amplitude level, (ii) the burst stimulus is maintained at or above an amplitude level greater than the reference amplitude level between spikes within a respective group of the plurality of spikes, (iii) each spike within each group is separated by a maximum inter-spike interval of 5 milliseconds, and (iv) each group is separated by a minimum inter-group interval of 20 milliseconds;
providing the burst stimulus from the implantable pulse generator to a medical lead; and
applying the burst stimulus to the nerve tissue of the patient via one or several electrodes of the medical lead.

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.
