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 cord modulation system to deliver a therapy signal to a patient'"'"'s spinal cord region for reducing or eliminating pain in the patient without performing a paresthesia mapping procedure, wherein the spinal cord modulation system includesan implantable signal delivery device, anda signal generator electrically coupleable to the implantable signal delivery device,the method comprising:
- programming the signal generator to(a) generate a non-paresthesia-producing therapy signal, wherein at least a portion of the therapy signal has a frequency in a frequency range of from 1.5 kHz to 100 kHz, and(b) deliver the therapy signal to a location in the patient'"'"'s spinal cord region, via the signal generator, without using paresthesia mapping to identify the location.

Abstract
Selective high-frequency spinal cord modulation for inhibiting pain with reduced side effects 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 cord region to address low back pain without creating unwanted sensory and/or motor side effects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.
