SELECTIVE HIGH FREQUENCY SPINAL CORD MODULATION FOR INHIBITING PAIN WITH REDUCED SIDE EFFECTS, AND ASSOCIATED SYSTEMS AND METHODS
First Claim
1. A method for configuring a spinal modulation system to deliver a therapy signal to a patient'"'"'s spinal cord region without performing a paresthesia mapping procedure, wherein the spinal modulation system includesan implantable signal delivery device implantable in the patient'"'"'s spinal cord region, proximate to a vertebral level in a range of from about T9 to about T12, wherein the implantable signal delivery device includes three or more electrical contacts, anda signal generator electrically coupleable to the implantable signal delivery device to generate a therapy signal and deliver the therapy signal to the patient'"'"'s spinal cord region via at least two of the electrical contacts of the implantable signal delivery device,the method comprising:
- programming or instructing the programming of the signal generator to generate a non-paresthesia-producing therapy signal, wherein at least a portion of the therapy signal is a 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, anda pulse width in a pulse width range of from about 25 microseconds to about 166 microseconds.

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.
