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.

19. A spinal cord modulation system for reducing or eliminating pain in a patient, comprising:
-
an implantable pulse generator having a machine-readable medium containing instructions for generating and transmitting a spinal modulation signal that at least partially reduces the patient'"'"'s sensation of pain without inducing paresthesia or tingling in the patient, wherein the spinal modulation signal is a bi-phasic square wave having a plurality of electrical pulses with pulse widths between 25 microseconds to 166 microseconds; and an implantable lead electrically coupled to the implantable pulse generator, wherein the electrical lead includes two or more electrodes configured to deliver the transmitted spinal modulation signal to a target location in the patient'"'"'s spinal cord. - View Dependent Claims (20, 21, 22, 23)

24. A spinal cord modulation system for reducing or eliminating back or leg pain in a patient, without relying on paresthesia or tingling to mask the patient'"'"'s sensation of the pain, the system comprising:
-
an implantable signal generator having a housing and one or more processors disposed within the housing, wherein the one or more processors are configured to generate a non-paresthesia-producing therapy signal, wherein the therapy signal is a bi-phasic square wave having a plurality of electrical pulses with pulse widths ranging from 10 microseconds to 333microseconds; and an elongated electrical lead electrically coupled to the implantable signal generator and configured to be implanted in the patient'"'"'s epidural space, wherein the electrical lead includes two or more electrodes configured to deliver the therapy signal to the patient'"'"'s spinal cord. - View Dependent Claims (25, 26, 27, 28, 29, 30)
