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, to at least partially alleviate a patient'"'"'s sensation of pain, without using paresthesia or tingling to mask the patient'"'"'s sensation of pain, wherein the spinal cord modulation system includesan implantable signal delivery device for implantation proximate to a vertebral level in a range of from T9 to T12, inclusive anda therapy signal generator electrically coupleable to the implantable signal delivery device and programmable to generate and deliver a therapy signal to the patient'"'"'s spinal cord via the implantable signal delivery device,the method comprising:
- programming the therapy signal generator to generate a non-paresthesia-producing therapy signal, wherein the therapy signal is a bi-phasic square-wave having(i) pulses with pulse widths between 25 microseconds and 166 microseconds, and(ii) a current amplitude in an amplitude range of from 0.5 mA to 10 mA.

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.
