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 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.

主权项

1. A method for programming a signal generator to deliver a therapy signal to a patient's spinal cord via at least one implantable signal delivery device, wherein the implantable signal delivery device is positioned to deliver the therapy signal to the patient's spinal cord at a vertebral level between T9 and T12, inclusively, the method comprising:
configuring the signal generator to generate a therapy signal, wherein the therapy signal is a plurality of bi-phasic pulses having a pulse width between 25 microseconds and 166 microseconds; and programming the signal generator to deliver the therapy signal at a frequency and amplitude that at least partially reduces the patient's sensation of pain without generating paresthesia.
