Claims
- 1. A device for reactively applying to a body site a varying electrical energy field developed from an originating portable energy source for stimulating repair or growth of tissue or bone structure in the body said device comprising:
- a portable energy source;
- means for producing a varying electrical energy field developed from said portable energy source;
- means for reactively applying to a body site said varying electrical energy field;
- means coupled to said reactively applied electrical energy field for extracting energy from said field during a portion of the varying field's cycle; and capacitor means for receiving said extracted energy.
- 2. The device as in claim 1 wherein the energy is extracted during the declining portion of the varying field cycle.
- 3. The device as in claim 1 wherein said means for extracting the energy comprises coil means in which the varying field induces a voltage, and said means for restoring the energy comprises circuit means for rectifying the induced voltage from said coil means and feeding it to said capacitor.
- 4. The device as in claim 1 comprising diode means for directing said extracted energy to said capacitor means.
- 5. In a device for reactively applying to a body site a varying electrical energy field developed from an originating battery source for stimulating repair or growth of tissue or bone structure in the body:
- a core;
- first electrical coil means wound around said core coupled to the originating energy source for developing said varying field from energy supplied by said originating source;
- second coil means wound around said core for extracting energy from said varying field during the declining portion of the varying field cycle;
- a capacitor coupled to said second coil means for recovering a portion of said extracted energy;
- switch means connected to both said second means and said capacitor; and
- rectifying means connected between said battery source and said first coil means.
- 6. The device as in claim 5 wherein said energy restoring means includes capacitor means connected between said first coil and said originating battery source.
