Abstract
Abstract Headache modulator apparatus and methodology employs a transcutaneous electronic wave to reduce and control migraine and vascular headaches. A pair of electrodes is placed transcranially, i.e., a first contact electrode is placed at one side of the cranium and a second electrode is placed at the opposite side of the cranium of the head. An electronic current wave comprising relatively high frequency pulses with a low frequency amplitude modulation is then applied between the positive and negative electrodes.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
73 words
A method (for relieving pain and symptoms associated with migraine and vascular headache syndromes) comprising securing a pair of electrodes wherein a first contact electrode is secured at one side of the head and a second contact electrode is secured at the opposite side of the patient's head and supplying an electronic current wave comprising a high frequency electrical wave bearing a low frequency amplitude modulation to said first and said second electrodes.
Claim 2
Independent Claim
73 words
A method (for relieving pain and symptoms associated with migraine and vascular headache syndromes) comprising securing a pair of electrodes wherein a first contact electrode is secured at one side of the head and a second contact electrode is secured at the opposite side of the patient's head and supplying an electronic current wave comprising a high frequency electrical wave bearing a low frequency amplitude modulation to said first and said second electrodes.
Claim 3
Dependent Claim
34 words
The method of claim 1, wherein the step of securing a pair of electrodes further comprises securing said first electrode over one temporal area and securing said second electrode over the opposite temporal area.
Claim 4
Dependent Claim
45 words
The method as in claim 1, wherein the step of securing a pair of electrodes further comprises securing said first electrode over a proximal aspect of one temporal bone area and securing said second electrode over a proximal aspect of the opposite temporal bone area.
Claim 5
Dependent Claim
43 words
The method as in claim 1, wherein the frequency of said high frequency electrical wave is in the range of 12-20 khz, wherein said low frequency modulation is in the range 8-20 hz, and wherein said wave does not exceed about 4 milliamperes.
Claim 6
Dependent Claim
12 words
The method as in claim 1, wherein said amplitude modulation is non-symmetrical.
Claim 7
Independent Claim
46 words
A method (for relieving pain and symptoms associated with migraine and vascular headache syndromes) comprising securing a pair of electrodes transcranially on a subject's head and supplying an electronic current wave comprising a high-frequency electrical wave bearing a low-frequency amplitude modulation to said pair of electrodes.
Claim 8
Independent Claim
46 words
A method (for relieving pain and symptoms associated with migraine and vascular headache syndromes) comprising securing a pair of electrodes transcranially on a subject's head and supplying an electronic current wave comprising a high-frequency electrical wave bearing a low-frequency amplitude modulation to said pair of electrodes.
Claim 9
Dependent Claim
39 words
The method of claim 6, wherein said high frequency electrical wave has a frequency range of 12-20 kHz, and said low-frequency amplitude modulation has a frequency range of 8-20 Hz, and said wave does not exceed about 4 milliamperes.
Claim 10
Dependent Claim
11 words
The method of claim 6, wherein said amplitude modulation is non-symmetrical.
