Abstract

A unique apparatus for multi-portal administration of radiofrequency range electromagnetic energy for therapeutic treatment of interior portions of various substrates including animals and humans which comprises an R.F. signal generator which is connected to a timer component having switching logic to apply R.F. electromagnetic energy one set at a time, sequentially across a plurality of sets of paired electrode plates, i.e., applicators. Each set of paired electrode plates is positioned on a different axis with reference to a fixed central point located between the plates at which such axes approximately intersect and which is the location of the portion to be treated.

The apparatus permits a fixed target, i.e., portion to be treated, to receive a constant input of R.F. energy although such energy is coming from different directions and emanating from different electrodes, hence several R.F. fields are created sequentially by the control mechanism as it functions.

Claims

1. In an apparatus for the application of radio frequency electromagnetic energy to a biological substrate including generator means for generation of radio frequency electromagnetic power and applicator means connected to the radio frequency power output of said generator means for applying said power output of said generator means to a said biological substrate, the improvement in which said applicator means comprises a plurality of applicator pairs for setting up a radio frequency electromagnetic field therebetween when connected to said radio frequency generator means, switching means for coupling the power output of said radio frequency generator means selectively across each said pair, one pair at a time, and control means for actuating said generator means including means for actuating said switching means to couple said power output thereof to each of said applicator pairs in predetermined sequence.

2. The improvement according to claim 1 wherein said radio frequency power output coupled to each said applicator pair is greater than 200 watts.

3. An apparatus according to claim 1 in which said control means includes a plurality of timer means, each timer means being associated with the actuation of said switching means with a different set of said pair of applicators whereby the time of actuation of each said set of paired appalicators is separately controlled from each other set of paired applicators.

4. An apparatus according to claim 1 in which said control means operates to deactuate said generator means when actuating said switching means to change the coupling of the radio frequency power of said generator means from one to another of said sets of paired applicators.
