SELECTIVE HIGH FREQUENCY SPINAL CORD MODULATION FOR INHIBITING PAIN WITH REDUCED SIDE EFFECTS, AND ASSOCIATED SYSTEMS AND METHODS
First Claim
1. A method for treating a patient with a spinal modulation system, wherein the spinal modulation system includes a pulse generator and a signal delivery element coupleable to the pulse generator, the method comprising:
- subcutaneously implanting the spinal modulation system such that the signal delivery element is positioned to apply to the patient'"'"'s spinal cord region a therapy signal that is generated by the pulse generator;
electrically coupling the signal delivery element to the pulse generator; and
configuring the pulse generator to generate the therapy signal, wherein at least a portion of the therapy signal isa bi-phasic square-wave havinga frequency in a frequency range of from about 3 kHz to about 20 kHz,a current amplitude in an amplitude range of from about 0.5 mA to about 4 mA,a pulse width between about 25 microseconds and about 166 microseconds, anddoes not induce paresthesia in the patient.

Abstract
Selective high-frequency spinal chord modulation for inhibiting pain with reduced side affects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient'"'"'s spinal chord region to address low back pain without creating unwanted sensory and/or motor side affects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.
