First Claim
Patent Images
1. A system for generating a therapeutic waveform, comprising:
- a pulse waveform generator that generates a waveform with a length of 1-20 ms and having at least one first phase having a first polarity and at least one second phase having a second polarity opposite of the first polarity, the at least one first phase having a leading edge, a trailing edge and a decay slope between the leading edge and the trailing edge and the decay slope having a phase tilt, the at least one second phase having a leading edge, a trailing edge and a decay slope between the leading edge and the trailing edge and the decay slot having a phase tilt; and
wherein an amplitude of the leading edge of the at least one first phase of the waveform is less than an amplitude of the leading edge of the at least one second phase of the waveform and a phase timing of the at least one first phase is less than a phase timing of the at least one second phase.

11. A method for generating a therapeutic pulse waveform, comprising:
-
generating, by the pulse waveform generator, a waveform with a length of 1-20 ms and having at least one first phase having a first polarity and at least one second phase having a second polarity opposite of the first polarity, wherein the first phase of the waveform has an amplitude that is less than an amplitude of the second phase of the waveform; controlling a duration and a shaping of each phase of the waveform, the controlling further comprising generating the at least one first phase having a leading edge, a trailing edge and a decay slope between the leading edge and the trailing edge and the decay slope having a phase tilt and generating the at least one second phase having a leading edge, a trailing edge and a decay slope between the leading edge and the trailing edge and the decay slot having a phase tilt; and wherein generating the waveform further comprises generating a waveform in which a phase timing of the at least one first phase is less than a phase timing of the at least one second phase. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
