Selective high frequency spinal cord modulation for inhibiting pain with reduced side effects, and associated systems and methods

摘要

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 100 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.

主权项

1. A spinal cord modulation system for reducing or eliminating pain in a patient, the system comprising:
a signal generator configured to generate a therapy signal in accordance with a therapy regimen, wherein at least a portion of the therapy signal is at a frequency in a frequency range from 1.5 kHz to 50 kHz; an implantable signal delivery device electrically coupled to the signal generator and configured to deliver the therapy signal to one or more target locations of the patient's spinal cord; and a programmer in wireless communication with the signal generator and configured to program the therapy regimen within the signal generator, wherein the therapy signal regimen includes
(a) a target location, and(b) a current amplitude that at least partially reduces the patient's sensation of pain without generating a sensation of paresthesia.
