1. A patient treatment device, comprising:
- an implantable pulse generator programmed to direct a pulsed electrical signal at a frequency of from about 1.5 kHz to about 20 kHz, the implantable pulse generator having a first connector positioned to couple to at least one implantable electrical lead; and
at least one implantable, elongated electrical lead having a proximal portion and a distal potion, the proximal portion having a second connector positioned to be connected to the first connector of the implantable pulse generator, the distal portion having multiple electrical contacts for delivering the pulsed electrical signal to one or more epidural locations along a patient'"'"'s spinal cord to reduce or inhibit at least one of chronic low-back pain and leg pain in the patient through application of the pulsed electrical signal, without the electrical signal creating at least one of;
(a) paresthesia;
(b) disruptions that are intrinsically detectable by the patient in sensory signals along the spinal cord, other than low-back pain and leg pain signals; and
(c) disruptions that are detectable by the patient in motor signals along the spinal cord.

Abstract
Selective high-frequency spinal chord modulation for inhibiting pain with reduced side affects 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 chord region to address low back pain without creating unwanted sensory and/or motor side affects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.

12. A patient treatment device, comprising:
-
at least one implantable electrical lead having a proximal portion and a distal potion, the lead being elongated along a lead axis between the proximal portion and the distal portion, the proximal portion having at least one lead connector, the distal portion having multiple electrical contacts arranged along the distal portion of the lead for delivering a pulsed electrical signal to one or more epidural locations along a patient'"'"'s spinal cord; and an implantable pulse generator having a pulse generator connector positioned to releasably couple to the lead connector of the at least one implantable electrical lead, the implantable pulse generator including a computer-readable medium programmed with instructions that, when executed, direct the pulsed electrical signal at a frequency of from about 5 kHz to about 15 kHz, to reduce or inhibit at least one of chronic low-back pain and leg pain in the patient, without the electrical signal creating; (a) paresthesia; and (b) disruptions that are intrinsically detectable by the patient in sensory signals along the spinal cord, other than low-back pain and leg pain signals; and (c) disruptions that are intrinsically detectable by the patient in motor signals along the spinal cord. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
