Multi-frequency neural treatments and associated systems and methods
View Patent ↗Multi-frequency neural treatments and associated systems and methods are disclosed. A method in accordance with a particular embodiment includes at least reducing patient pain by applying a first electrical signal to a first target location of the patient's spinal cord region at a frequency in a first frequency range of up to about 1,500 Hz, and applying a second electrical signal to a second target location of the patient's spinal cord region at a frequency in a second frequency range of from about 2,500 Hz to about 100,000 Hz.
1. A method for alleviating patient pain or discomfort, without relying on paresthesia or tingling to mask the patient's sensation of the pain, comprising:
implanting a percutaneous lead in the patient's epidural space, wherein the percutaneous lead includes at least one electrode, and wherein implanting the percutaneous lead includes positioning the at least one electrode proximate to a target location in the patient's spinal cord region and outside the sacral region;
implanting a signal generator in the patient;
electrically coupling the percutaneous lead to the signal generator; and
programming the signal generator to generate and deliver an electrical therapy signal to the spinal cord region, via the at least one electrode, wherein at least a portion of the electrical therapy signal is at a frequency in a frequency range of from about 2,500 Hz to about 100,000 Hz.
2. The method of claim 1
wherein the target location includes the patient's dorsal column.
3. The method of claim 1
wherein the at least one electrode is located toward a distal end of the percutaneous lead.
4. The method of claim 1 , wherein at least a portion of the electrical therapy signal is at a frequency in a frequency range of from about 2,500 Hz to about 20,000 Hz.
5. The method of claim 1 , wherein at least a portion of the electrical therapy signal is at a frequency in a frequency range of from about 3,000 Hz to about 10,000 Hz.
6. The method of claim 1 , further comprising:
applying a stimulation signal to the patient's spinal cord region, wherein the stimulation signal is at a frequency in a frequency range of from about 40 Hz to about 500 Hz.
7. The method of claim 1 , wherein the electrical therapy signal is applied continuously.
8. The method of claim 1 , wherein the electrical therapy signal is applied discontinuously so as to include periods when the electrical therapy signal is applied, and periods when the electrical therapy signal is terminated.
9. The method of claim 8 , wherein the periods when the electrical therapy signal is applied range from a few seconds to a few hours.
10. The method of claim 1 , wherein the electrical therapy signal is applied discontinuously so as to include periods when the electrical therapy signal is applied, and periods when the electrical therapy signal is terminated according to a duty cycle.
11. A method for alleviating patient pain or discomfort, without relying on paresthesia or tingling to mask the patient's sensation of the pain, comprising:
implanting a percutaneous lead in the patient's epidural space, wherein the percutaneous lead includes at least one electrode, and wherein implanting the percutaneous lead includes positioning the at least one electrode proximate to a target location in the patient's spinal cord region and outside the scaral region;
implanting a signal generator in the patient;
electrically coupling the percutaneous lead to the signal generator; and
programming the signal generator to generate and deliver an electrical therapy signal to the spinal cord region, via the at least one electrode, wherein at least a portion of the electrical therapy signal is at a frequency in a frequency range of from about 2,500 Hz to about 100,000 Hz and a current amplitude between about 2 mA and about 20 mA.
12. The method of claim 11 , further comprising:
programming the signal generator to generate and deliver the electrical therapy signal at a duty cycle of less than 50%.
