Abstract
The method and system described herein relate to stimulating nerve tissue using a pulse generator. A stimulus is created that comprises a signal that is produced from a frequency spectrum having a power spectral density per unit of bandwidth proportional to 1/fβ, wherein β is excludes 0. The stimulus is provided from the pulse generator to at least one stimulation lead; and applied to nerve tissue via one or several electrodes.
Claims10
An implantable pulse generator (IPG) for neurostimulation of a patient, comprising:
- a battery for powering the IPG;
- a processor for controlling the IPG according to executable instructions;
- memory for storing executable instructions and data;
- and pulse generating circuitry for generating electrical pulses for stimulation of nerve tissue of the patient;
- wherein (1) the processor controls pulse generation operations of the IPG according to one or more stimulation programs defined by a clinician of the patient, (2) IPG is programmable by the clinician to select from multiple stimulation patterns for pulse generation including a noise stimulation pattern, (3) the IPG is programmed to retrieve a parameter β from a respective stimulation program defined for the noise stimulation pattern to generate electrical pulses generally exhibiting amplitude variations for a noise power density profile of 1/f∧β where f represents frequency, and (4) the parameter β for the respective stimulation program is selectable by the clinician from a range of values including β=1, β=2, and multiple values therebetween.
