System and method for coupling burst and tonic stimulation

摘要

A system and method for delivering coupled burst and tonic stimulation of nervous tissue is provided. The system and method includes providing a lead with at least one stimulation electrode configured to be implanted at a target position proximate to nervous tissue of interest. The system and method further includes coupling the lead to an implantable pulse generator (IPG). The method delivers a first current pulse configured as a tonic stimulation waveform to the at least one electrode. The tonic stimulation waveform is configured to excite A-beta fibers of the nervous tissue. After a tonic-burst delay, the IPG delivers second current pulses configured as a burst stimulation waveform to at least one electrode. The burst stimulation waveform is configured to excite C-fibers of the nervous tissue.

1. A method for controlling burst stimulation of nervous tissue of a patient, the method comprising:
providing a lead having at least one electrode on the lead configured to be implanted at a target position proximate to nervous tissue of interest; delivering a first current pulse configured as a tonic stimulation waveform to the at least one electrode, the tonic stimulation waveform configured to excite A-beta fibers of the nervous tissue; after a tonic-burst delay, delivering second current pulses configured as a burst stimulation waveform to the at least one electrode, the burst stimulation waveform configured to excite C-fibers of the nervous tissue; and adjusting the tonic-burst delay between the tonic and burst stimulation waveforms to deliver the burst stimulation waveform during a refractory period of the A-beta fibers excited by the tonic stimulation waveform to avoid excitation of the A-beta fibers excited by the tonic stimulation waveform.
