Claims Analysis
Total Claims: 31
Claim 1
Independent Claim
57 words
A therapeutic method for reducing the incidence of adhesions which are likely to form in regions of inflamed body tissue, comprising the step of exposing said tissues to low frequency sound to reduce the incidence of said adhesions, said exposure being periodic and occurring at least during a period of time when said body tissues are inflamed.
Claim 2
Dependent Claim
57 words
A therapeutic method for reducing the incidence of adhesions which are likely to form in regions of inflamed body tissue, comprising the step of exposing said tissues to low frequency sound to reduce the incidence of said adhesions, said exposure being periodic and occurring at least during a period of time when said body tissues are inflamed.
Claim 3
Dependent Claim
25 words
The therapeutic method of claim 1 wherein said tissues are exposed to said low frequency sound following trauma sustained in the region of said tissues.
Claim 4
Dependent Claim
10 words
The method of claim 2 wherein said trauma is surgery.
Claim 5
Dependent Claim
12 words
The therapeutic method of claim 1 wherein said tissues are intra-abdominal tissues.
Claim 6
Dependent Claim
15 words
The therapeutic method of claim 4 wherein said tissues are the tissues of intra-abdominal organs.
Claim 7
Dependent Claim
13 words
The therapeutic method of claim 5 wherein said intra-abdominal organs are intestinal organs.
Claim 8
Dependent Claim
21 words
The therapeutic method of claim 1 wherein said periodic exposure continues at least until said body tissues are no longer inflamed.
Claim 9
Dependent Claim
16 words
The therapeutic method of claim 7 wherein said periodic exposure occurs at least once per minute.
Claim 10
Dependent Claim
19 words
The therapeutic method of claim 8 wherein each periodic exposure continues for a period of at least 1 second.
Claim 11
Dependent Claim
22 words
The therapeutic method of claim 1 wherein said exposure begins following surgery and continues for a period of at least 6 hours.
Claim 12
Dependent Claim
17 words
The therapeutic method of claim 10 wherein said exposure continues for at least 48 hours following surgery.
Claim 13
Dependent Claim
21 words
The therapeutic method of claim 1 wherein said low frequency sound has a frequency between 1 and 50 cycles per second.
Claim 14
Dependent Claim
22 words
The therapeutic method of claim 12 wherein said low frequency sound has a frequency of between 5 and 35 cycles per second.
Claim 15
Dependent Claim
33 words
The therapeutic method of claim 1 wherein said inflamed body tissues comprise organs, and wherein said low frequency sound comprises a resonant frequency of at least one of said organs to be treated.
Claim 16
Dependent Claim
24 words
The therapeutic method of claim 1 wherein the patient is exposed to low frequency sound having an amplitude of between 100 and 180 dB.
Claim 17
Dependent Claim
17 words
The therapeutic method of claim 15 wherein said amplitude of low frequency sound is between 120-160 dB.
Claim 18
Dependent Claim
12 words
The method of claim 16 wherein said amplitude is about 140 dB.
Claim 19
Dependent Claim
69 words
A therapeutic method for reducing the incidence of adhesions which are likely to form in regions of inflamed body tissues, comprising the step of exposing said tissues to low frequency sound to reduce the incidence of adhesions, said low frequency sound having a frequency of between 5 and 35 cycles per second and being varied during such exposure through a range of from 5 to 35 cycles per second.
Claim 20
Dependent Claim
69 words
A therapeutic method for reducing the incidence of adhesions which are likely to form in regions of inflamed body tissues, comprising the step of exposing said tissues to low frequency sound to reduce the incidence of adhesions, said low frequency sound having a frequency of between 5 and 35 cycles per second and being varied during such exposure through a range of from 5 to 35 cycles per second.
Claim 21
Dependent Claim
18 words
The therapeutic method of claim 18 wherein said low frequency sound is generated by an audio type speaker.
Claim 22
Dependent Claim
17 words
The therapeutic method of claim 19 wherein said audio speaker is driven by a sine wave signal.
Claim 23
Dependent Claim
18 words
The therapeutic method of claim 20 wherein said sine wave signal varies in frequency during its duty cycle.
Claim 24
Dependent Claim
23 words
The therapeutic method of claim 21 wherein said sine wave signal is interrupted with a pause of preselected duration between said duty cycles.
Claim 25
Independent Claim
60 words
A method of treating internal body tissues comprising the steps of: (a) performing surgery to at least gain access to said internal body tissues; and (b) applying low frequency sound to said body tissues during at least a portion of the period of healing to reduce the incidence of adhesions which might otherwise form in the region of said tissues.
Claim 26
Independent Claim
60 words
A method of treating internal body tissues comprising the steps of: (a) performing surgery to at least gain access to said internal body tissues; and (b) applying low frequency sound to said body tissues during at least a portion of the period of healing to reduce the incidence of adhesions which might otherwise form in the region of said tissues.
Claim 27
Dependent Claim
20 words
The method of claim 23 further comprising the step of introducing a prosthesis into the region of said internal tissues.
Claim 28
Dependent Claim
12 words
The method of claim 24 wherein said prosthesis is a surgical suture.
Claim 29
Dependent Claim
12 words
The method of claim 23 wherein said suture is a surgical staple.
Claim 30
Dependent Claim
63 words
A therapeutic method for reducing the incidence of adhesions which are likely to form in regions of inflamed body tissues, comprising the step of exposing said tissues to low frequency sound to reduce said adhesions, said low frequency sound being generated by an audio type speaker which is driven by a sine wave signal which is varied in frequency during its duty cycle.
Claim 31
Dependent Claim
63 words
