Abstract
Apparatus and methods for managing pain uses a single composite modulation/stimulation signal with variable characteristics to achieve the same results as separate varying electromagnetic signals, including spinal cord stimulation or peripheral nerve stimulation.
Claims20
A system comprising:
- a signal generator;
- and
- processing circuitry configured to:
- control the signal generator to deliver a biphasic signal to a nerve area for a first period of time;
- control the signal generator to apply, via one or more electrodes, a first phase segment of the biphasic signal to the nerve area during the first period of time, the first phase segment having a first frequency;
- control the signal generator to apply, via the one or more electrodes, a second phase segment of the biphasic signal to the nerve area during the first period of time, the second phase segment having a second frequency lower than the first frequency of the first phase segment;
- and
- subsequent to applying the biphasic signal to the nerve area for the first period of time, control the signal generator to turn off the biphasic signal for a second period of time greater than the first period of time.
