1. An epidural spinal cord stimulation system for reducing or eliminating pain in a patient without using paresthesia to treat the patient, the system comprising:
- a programmer having a therapy program that, when executed, directs delivery of a therapy signal by a spinal cord modulator to a signal delivery device configured to deliver the therapy signal to the patient'"'"'s spinal cord, wherein the therapy signal at least partially reduces pain without generating paresthesia, and wherein the therapy signal includes a plurality of sequential biphasic pulses, with the pulses having pulse widths in a pulse width range from 25 microseconds to 166 microseconds.

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.

11. An epidural spinal cord modulation system for treating back and/or leg pain of a patient without requiring paresthesia mapping of the patient to implant and configure the modulation system, the system comprising:
a programmer having a therapy program that, when executed, directs delivery of a therapy signal by a spinal cord modulator to a signal delivery device configured to deliver the therapy signal to the patient'"'"'s spinal cord, wherein the therapy signal is a non-paresthesia producing therapy signal having a plurality of sequential biphasic square-wave pulses, with the pulses having pulse widths in a pulse width range from 30 microseconds to 35 microseconds, and wherein the therapy signal is at a current amplitude in a current amplitude range from 0.5 mA to 10 mA, and wherein the programmer is configured to transmit the program to the spinal cord modulator. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
