1. A spinal cord modulation system for reducing or eliminating pain in a patient, the system comprising:
- a voltage-controlled pulse generator configured to generate a non-paresthesia-producing therapy signal, wherein at least a portion of the therapy signal is at a frequency in a frequency range from 1.5 kHz to 100 kHz; and
an implantable signal delivery device electrically coupled to the pulse generator and configured to deliver the therapy signal to the patient'"'"'s spinal cord.

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.

27. 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 with a constant voltage arrangement, wherein at least a portion of the therapy signal is at a frequency in a frequency range from 1.5 kHz to 50 kHz; 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 (28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A spinal cord modulation system for reducing or eliminating pain in a patient, comprising:
-
a voltage-controlled implantable pulse generator having a constant voltage arrangement and 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 relying on paresthesia or tingling to mask the patient'"'"'s sensation of the pain, wherein at least a portion of the spinal modulation signal is at a frequency in a frequency range from 3 kHz to 20 kHz, and has a pulse width in a pulse width range from 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 (38, 39, 40, 41)
