Patent ID: 8874221

Claim:
A method for treating a patient with a spinal modulation system, wherein the spinal modulation system includes a pulse generator and a signal delivery element coupleable to the pulse generator, the method comprising: subcutaneously implanting the spinal modulation system such that the signal delivery element is positioned to apply to the patient's spinal cord region a therapy signal that is generated by the pulse generator; electrically coupling the signal delivery element to the pulse generator; and configuring the pulse generator to generate the therapy signal, wherein at least a portion of the therapy signal is a bi-phasic square-wave having a frequency in a frequency range of from about 3 kHz to about 20 kHz, a current amplitude in an amplitude range of from about 0.5 mA to about 4 mA, a pulse width between about 25 microseconds and about 166 microseconds, and does not induce paresthesia in the patient.
