1. A spinal cord stimulation system for reducing or eliminating pain in a patient, the system comprising:
- an implantable signal generator having a computer-readable medium with instructions to generate and transmit a non-paresthesia-producing therapy signal, wherein at least a portion of the therapy signal is at a frequency of from 1,000 Hz to 1,500 Hz, with a pulse width in a pulse width range from 10 microseconds to 50 microseconds, and a current amplitude in a current amplitude range from 0.5 to 20 mA; and
a signal delivery device electrically coupleable to the implantable signal generator and designed to be implanted in the patient'"'"'s epidural space to deliver the therapy signal to the dorsal column of the patient'"'"'s spinal cord.

Abstract
Short pulse width spinal cord modulation for inhibiting pain with reduced side effects and associated systems and methods are disclosed. In particular embodiments, modulation signal has pulse widths in the range of from about 10 microseconds to about 50 microseconds may be applied to the patient'"'"'s spinal cord region to address chronic pain without using paresthesia or tingling to mask or cover the patient'"'"'s sensation of pain. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.
