Abstract

The invention contemplates a boot removably adapted for attachment to an engine hoof and carrying at least one multi-turn electrical coil which effectively surrounds at least the bottom of the hoof. A pulse generator and power source are self-contained in a housing carried at the back side of the boot, with provision for electrically exciting the coil with a succession of therapeutically beneficial low-voltage unidirectional asymmetrical pulses.

Claims

1. An electromagnetic body-treatment device for surgically non-invasive modification of the growth repair and maintenance behavior of living tissues and/or cells within an equine hoof by a specific and selective change in electrical environment, comprising a boot of magnetically transparent material and having a relatively stiff sole portion and a relatively flexible upper portion peripherally connected to the sole portion, the upper portion being shaped for removable conforming application to hoof side contour, the bottom of said sole portion being characterized by an integral downward projection of horseshoe shape and with a multi-turn electrical coil embedded in the horseshoe region of said sole portion, the turns of said coil being generally in the horizontal plane of said sole portion and defining a magnetically transparent included area in substantial conformance with that of the bottom area of the hoof, whereby said coil is poised to establish an upstanding axis of symmetry of magnetic-flux concentration in the hoof, and self-contained means carried by said boot and connected to said coil for electrically exciting said coil with a succession of low-voltage unidirectional asymmetrical pulses.

2. The treatment device of claim 1, in which said coil is one of two, the second coil being of size to accommodate hoof insertion and being carried by the upper portion of said boot in a substantially horizontal plane, said second coil being electrically connected to said self-contained means and in flux-aiding relation to flux development attributable to said first-mentioned coil.

3. The treatment device of claim 2, in which said coils are series-connected to said last-defined means.

4. The treatment device of claim 2, in which said second coil is detachably connected to said upper portion and is detachably connected to said last-defined means.

5. The treatment device of claim 4, in which said second coil includes magnetically transparent mounting means, and in which a circumferential strap is threaded through locating apertures in said upper portion and in said mounting means to retain the connected relation of said second coil with said upper portion.

7. The treatment device of claim 1 or claim 2 or claim 6, in which said pulses are in bursts at a burst-repetition rate in the range of one to 5 Hz, wherein pulses within each burst are in the repetition-rate range of 2 to 5 kHz, and wherein burst duration is approximately one tenth the period of burst repetition.

8. The treatment device of claim 1 or claim 2 or claim 6, in which said pulses are in bursts at a burst-repetition rate of about 2 Hz, wherein pulses within each burst are at a repetition rate of 3 to 4 kHz, and wherein burst duration is approximately one tenth the period of burst repetition.

9. The treatment device of claim 1 or claim 2 or claim 6, in which said boot is a single molded product of plastic material.

10. The treatment device of claim 1 or claim 2 or claim 6, in which said last-defined means includes a housing mounted to the back side of said upper portion and contains a source of electric power, an externally accessible switch for on-off control of said excitation, and an externally viewable indicator of operational state.

6. An electromagnetic body-treatment device for surgically non-invasive modification of the growth repair and maintenance behavior of living tissues and/or cells within an equine hoof by a specific and selective change in electrical environment, comprising a boot of magnetically transparent material and having a relatively stiff sole portion and a relatively flexible upper portion peripherally connected to the sole portion, the upper portion being shaped for removable conforming application to hoof side contour, a single multi-turn electrical coil carried by said upper portion, the turns of said coil conforming generally to the outer contour of said upper portion and being in vertically spaced progression to substantially the vertical extent of said upper portion, and self-contained means carried by said boot and connected to said coil for electrically exciting said coil with a succession of low-voltage unidirectional asymmetrical pulses.
