Abstract
Abstract An electrical apparatus applies an electric field, e.g. a r.f. field, in a timed manner such that over a given cycle period, e.g. 24 hours, the field is applied for a selected portion of the cycle period and is switched off for the remainder of the period. The periods may be programmable utilizing a microprocessor. The field strength may be selected so as not to produce significant tissue heating, typically less than approximately 100 μw/cm 2 , measured at a system surface.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
94 words
Electrical apparatus for treating a living system to influence a metabolic growth parameter of the living system, the apparatus comprising: field applying means for applying to the system a radio frequency electromagnetic field having a predetermined characteristic and at a power level, measured adjacent a system surface, of not more than approximately 100 μw/cm 2 , for influencing the metabolic growth parameter but without producing bulk heating of the system; and, timing means for causing the field applying means to apply said field with said characteristic repetitively, for treatment periods spaced apart in time.
Claim 2
Dependent Claim
94 words
Electrical apparatus for treating a living system to influence a metabolic growth parameter of the living system, the apparatus comprising: field applying means for applying to the system a radio frequency electromagnetic field having a predetermined characteristic and at a power level, measured adjacent a system surface, of not more than approximately 100 μw/cm 2 , for influencing the metabolic growth parameter but without producing bulk heating of the system; and, timing means for causing the field applying means to apply said field with said characteristic repetitively, for treatment periods spaced apart in time.
Claim 3
Dependent Claim
40 words
Apparatus according to claim 1, wherein said field applying means comprises an r.f. oscillator for producing a pulsed r.f. field; and, the timing means is connected to control the oscillator for intermittent operation defining said spaced apart treatment time periods.
Claim 4
Dependent Claim
31 words
Apparatus according to claim 2, wherein the timing means defines a sequence of cycle periods and enables operation of said field applying means for a predetermined portion of each cycle period.
Claim 5
Dependent Claim
20 words
Apparatus according to claim 3, further comprising means for selecting the duration of said predetermined portion of the cycle period.
Claim 6
Dependent Claim
23 words
Apparatus according to claim 3 further comprising display means for displaying the number of cycle periods for which the apparatus has been operative.
Claim 7
Dependent Claim
40 words
Apparatus according to claim 3, further comprising means for defining the number of cycle periods for which the apparatus is to operate; and, display means for indicating the number of cycle periods to be performed for achieving the defined number.
Claim 8
Dependent Claim
22 words
Apparatus according to claim 1, wherein said timing means comprises means for storing program instructions to control the duration of said periods.
Claim 9
Dependent Claim
23 words
Apparatus according to claim 1, further comprising detector means for detecting operation of said field applying means for verifying operation of the apparatus.
Claim 10
Dependent Claim
22 words
Apparatus according to claim 1, further comprising means for selecting the intensity of the electric field produced by the field applying means.
Claim 11
Dependent Claim
69 words
Electrical therapy apparatus, comprising: means for applying a radio frequency electromagnetic field to living tissue at a power level, measured adjacent a tissue surface, of not more than approximately 100 μw/cm 2 , to promote healing thereof but without producing any significant tissue heating; and, timing means for intermittently applying the field, whereby energy consumption by the field applying means can be substantially reduced without dimunition in healing rate.
Claim 12
Dependent Claim
69 words
Electrical therapy apparatus, comprising: means for applying a radio frequency electromagnetic field to living tissue at a power level, measured adjacent a tissue surface, of not more than approximately 100 μw/cm 2 , to promote healing thereof but without producing any significant tissue heating; and, timing means for intermittently applying the field, whereby energy consumption by the field applying means can be substantially reduced without dimunition in healing rate.
Claim 13
Independent Claim
72 words
A method for influencing a metabolic growth characteristic of a living system, comprising the steps of: applying an electric field to a living system at a power level, measured adjacent a system surface, of not more that approximately 100 μw/cm 2 , to alter a metabolic characteristic thereof without thereby heating the living system; and, periodically interrupting the applying step so that the field is applied repetitively for spaced apart time periods.
Claim 14
Independent Claim
72 words
A method for influencing a metabolic growth characteristic of a living system, comprising the steps of: applying an electric field to a living system at a power level, measured adjacent a system surface, of not more that approximately 100 μw/cm 2 , to alter a metabolic characteristic thereof without thereby heating the living system; and, periodically interrupting the applying step so that the field is applied repetitively for spaced apart time periods.
Claim 15
Independent Claim
62 words
A method of therapy, comprising the steps of: applying to living tissue a radio frequency electromagnetic field at a power level, measured adjacent a tissue surface, of not more than approximately 100 μw/cm 2 , to promote tissue healing but without producing any significant tissue heating; and, periodically interrupting the applying step to apply the field intermittently at a predetermined duty cycle.
Claim 16
Independent Claim
62 words
A method of therapy, comprising the steps of: applying to living tissue a radio frequency electromagnetic field at a power level, measured adjacent a tissue surface, of not more than approximately 100 μw/cm 2 , to promote tissue healing but without producing any significant tissue heating; and, periodically interrupting the applying step to apply the field intermittently at a predetermined duty cycle.
