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 patient therapy system for alleviating a patient's pain or discomfort without using paresthesia or tingling to mask the patient's sensation of pain or discomfort, the system comprising:
a signal generator programmed to generate an electrical therapy signal, wherein at least a portion of the therapy signal is at a frequency in a frequency range between 1.5 kHz and 100 kHz, and at least partially alleviates pain or discomfort without generating or using paresthesia to mask the patient's sensation of pain or discomfort; and an implantable signal delivery device electrically coupleable to the signal generator and configured to deliver the therapy signal to a patient's spinal cord region, and wherein the implantable signal delivery device has one or more electrical contacts configured to be positioned laterally from a midline of the patient's spinal cord so as to be proximate to a dorsal root, dorsal root entry zone, or dorsal root ganglion.
