Abstract

An electromagnetic stimulation device which is comprised of a plurality of overlapping coils which are able to be independently energized in a predetermined sequence such that each coil will generate its own independent electromagnetic field and significantly increase the adjacent field. The coils are co-planar and are disposed in an ergonomic body wrap, which is properly marked to permit an unskilled patient to locate the body wrap, on a particular part of the body, of the patient so that the stimulation coils will maximize the electromagnetic stimulation on the selected nerves, muscles, and/or body tissues near the treated area. The device can be used to treat medical conditions including: muscular atrophy, neuropathic bladder and bowel, musculoskeletal pain, arthritis, as well as possible future applications in the prevention of deep vein thrombosis and weight reduction.

Claims

1. An electromagnetic stimulating device comprising a plurality of overlapping stimulator coils for conducting electrical current disposed in an ergonomic flexible body-contoured wrap capable of being adjustably and temporarily secured to the body of a patient in an appropriate orientation by an unskilled user;

and an electrical current means connected to said overlapping stimulator coils so as to be able to independently energize each coil in a predetermined sequence such that each coil will generate its own independent electromagnetic field.

2. The electromagnetic stimulating device of claim 1, wherein said overlapping stimulator coils are co-planar.

3. The electromagnetic stimulating device of claim 1, wherein said flexible body wrap has marking indicia to enable an unskilled user to position said body wrap such that said overlapping stimulator coils are properly disposed to enable optimum nerve stimulation.

4. The electromagnetic stimulating device of claim 1, wherein said flexible body wrap is disposable.

5. The electromagnetic stimulating device of claim 1, wherein said plurality of overlapping stimulator coils comprises three overlapping stimulator coils, one center target coil and two flanking coils which can be sequentially or simultaneously electrically energized to create an electromagnetic field near said target coil which is substantially greater than in any single stimulator or flanking coil.

6. A method to electromagnetically stimulate anatomic regions of a patient to prevent and treat medical conditions including:

muscular atrophy, musculoskeletal pain, arthritis, urinary incontinence, neuropathic bowel and bladder as well as weight loss, comprising the steps of;

(a) providing an electromagnetic stimulating device having a plurality of overlapping stimulator coils for conducting electrical current;

(b) providing an electrical current means connected to said overlapping stimulator coils so as to be able to independently energize each coil in a predetermined sequence such that each coil will generate its own independent electromagnetic field;

(c) providing an ergonomic flexible body wrap capable of being adjustably and temporarily secured to the body of said patient in which said overlapping stimulator coils are disposed;

(d) stimulating the appropriate body tissues of said patient by sequentially or simultaneously electrically energizing said plurality of overlapping coils in said ergonomic flexible body wrap thereby creating alternating and pulsating electromagnetic fields.

7. An electromagnetic stimulating device comprising:

(a) a plurality of overlapping stimulator coils for conducting electrical current, which are co-planar and arc disposed in an ergonomic flexible body wrap capable of being secured to the body of a patient;

(b) an electrical current means connected to said overlapping stimulator coils so as to be able to independently energize each coil in a predetermined sequence such that each coil will generate its own independent electromagnetic field;

whereby, anatomic regions of a patient can be stimulated so as to prevent and treat medical conditions including;

muscular atrophy, musculoskeletal pain, arthritis, urinary incontinence, neuropathic bowel and bladder as well as weight loss.

8. The electromagnetic nerve stimulating device of claim 7, wherein said flexible body wrap has marking indicia to enable an unskilled user to position said body wrap such that said overlapping stimulator coils are properly disposed to enable optimum stimulation of the anatomic region.

9. The electromagnetic stimulating device of claim 7, wherein said flexible body wrap is disposable.

10. The electromagnetic stimulating device of claim 7, wherein there are three or more overlapping stimulator coils, one center target coil and two or more flanking coils which can be sequentially or simultaneously electrically energized to create an electromagnetic field near said target coil which is substantially greater than in any one of said stimulator or flanking coil.
