Abstract
Abstract A transcutaneous stimulator for stimulating portions of the body. The output of the stimulator is a stimulating pulse having frequency components falling within predetermined frequency band limits so as to optimally excite touch nerve fibres relative to nociceptor or pain receptor nerve fibres.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
67 words
A stimulator adapted for use as a transcutaneous stimulator for the purpose of organic pain suppression which comprises: pulse generator means; filter means for transforming the pulses of the pulse generator means into output pulses each comprising a plurality of frequency components having substantially 90 percent of their energy throughout substantially 100-5,000 Hz; and output means connected to said filter means for applying said transformed pulses transcutaneously.
Claim 2
Dependent Claim
67 words
A stimulator adapted for use as a transcutaneous stimulator for the purpose of organic pain suppression which comprises: pulse generator means; filter means for transforming the pulses of the pulse generator means into output pulses each comprising a plurality of frequency components having substantially 90 percent of their energy throughout substantially 100-5,000 Hz; and output means connected to said filter means for applying said transformed pulses transcutaneously.
Claim 3
Dependent Claim
13 words
The stimulator of claim 1 wherein the transformed pulses are full cycle pulses.
Claim 4
Dependent Claim
13 words
The stimulator of claim 1 wherein the transformed pulses are half cycle pulses.
Claim 5
Dependent Claim
23 words
The stimulator of claim 1 wherein said output means further comprises constant current means for regulating the current output of said filter means.
Claim 6
Dependent Claim
42 words
A transcutaneous stimulator which comprises: means for producing a series of pulses, each of said pulses having frequency components substantially 90 percent of the energy of which falls within substantially 100-5,000 Hz and output means connected to said pulse series producing means.
Claim 7
Dependent Claim
42 words
A transcutaneous stimulator which comprises: means for producing a series of pulses, each of said pulses having frequency components substantially 90 percent of the energy of which falls within substantially 100-5,000 Hz and output means connected to said pulse series producing means.
Claim 8
Dependent Claim
13 words

Claim 9
Dependent Claim
13 words
The transcutaneous stimulator of claim 5 wherein the pulses are half cycle pulses.
Claim 10
Independent Claim
46 words
A method of transcutaneous stimulation which comprises the steps of: producing a series of pulses, each of said pulses comprising a plurality of frequency components having substantially 90 percent of their energy throughout substantially 100-5,000 Hz; and applying the pulses to the portion of the body.
Claim 11
Independent Claim
46 words
A method of transcutaneous stimulation which comprises the steps of: producing a series of pulses, each of said pulses comprising a plurality of frequency components having substantially 90 percent of their energy throughout substantially 100-5,000 Hz; and applying the pulses to the portion of the body.
