Abstract

A technique and device for preventing and/or treating osteoporosis, hip and spine fractures, and/or spine fusions by incorporating at least one conductive coil (110) into a garment (90) adapted to be worn adjacent to the patient'"'"'s skin over a treatment area and applying an electrical signal to the coil effective to produce a magnetic flux the penetrates the treatment area so as to produce an electric field in the bones and the treatment area.

Claims

1. A method of preventing and/or treating osteoporosis, bone fracture, and/or bone fusion in a patient, comprising the steps of:

incorporating at least one conductive coil N turns, where N>

1, into an article of clothing adapted to be worn on the patient'"'"'s torso adjacent the patient'"'"'s skin, whereby the article of clothing, when worn, causes the coil to be located over a treatment area of the patient; and

applying an electrical signal to the coil effective to produce a magnetic flux that penetrates the treatment area so as to produce an electric field in the treatment area effective to treat osteoporosis, fracture and/or fusion of bones of the treatment area.

2. The method of claim 1, comprising the additional step of providing a portable power device that creates said electrical signal for application to the coil, said portable power device being sufficiently small and light to be carried on the patient'"'"'s body when the article of clothing is being worn.

3. The method of claim 2, wherein the portable power device is adapted to provide to said coil a 60 kHz sinusoidal electrical current with a sine wave amplitude of 100 mA.

4. The method of claim 1, wherein the article of clothing is an undershirt and the coil is configured in a racetrack design having a long axis along the treatment area of the patient'"'"'s spine when incorporated into the undershirt.

5. The method of claim 4, wherein the coil is woven into the undershirt.

6. The method of claim 4, wherein the coil is placed in a pouch in the undershirt.

7. The method of claim 4, wherein the coil is attached to the undershirt by VELCRO®

.

8. The method of claim 1, wherein the article of clothing is underpants and the coil is generally circular in shape and centered over the patient'"'"'s hip when incorporated into the underpants.

9. The method of claim 8, wherein the coil is woven into the underpants.

10. The method of claim 8, wherein the coil is placed in a pouch in the underpants.

11. The method of claim 8, wherein the coil is attached to the underpants by VELCRO®

.

12. The method of claim 8, wherein the underpants are adapted to accept a generally circular-shaped coil over both hips of the patient.

13. A system for preventing and/or treating osteoporosis, bone fracture, and/or bone fusion in a patient, comprising:

an article of clothing adapted to be worn on the patient'"'"'s torso adjacent the patient'"'"'s skin, said article of clothing including at least one conductive coil N turns, where N>

1, incorporated therein such that, when worn, the coil is located over a treatment area of the patient; and

a portable signal generating device that generates an electrical signal for application to the coil to produce a magnetic flux that penetrates the treatment area so as to produce an electric field in the bones of the treatment area effective to treat osteoporosis, bone fracture and/or bone fusion of bones of the treatment area.

14. The system of claim 13, wherein the portable signal generating device comprises a rechargeable battery and is sufficiently small and light to be carried on the patient'"'"'s body when the article of clothing is being worn.

15. The system of claim 13, wherein the portable signal generating device is adapted to provide to said coil a sinusoidal electrical current in a frequency range of 30 kHz to 250 kHz with a sine wave amplitude of 100 mA.

16. The system of claim 15, wherein the portable signal generating device is adapted to provide to said coil a 60 kHz sinusoidal electric current.

17. The system of claim 13, wherein the article of clothing is an undershirt and the coil is configured in a racetrack design having a long axis along the treatment area of the patient'"'"'s spine when incorporated into the undershirt.

18. The system of claim 17, wherein the coil is woven into the undershirt.

19. The system of claim 17, wherein the undershirt includes a pouch for accepting the coil.

20. The system of claim 17, wherein the undershirt includes VELCRO®

strips for accepting the coil.

21. The system of claim 13, wherein the article of clothing is underpants and the coil is generally circular in shape and centered over the patient'"'"'s hip when incorporated into the underpants.

22. The system of claim 21, wherein the coil is woven into the underpants.

23. The system of claim 21, wherein the underpants include a pouch for accepting the coil.

24. The system of claim 21, wherein the coil is attached to the underpants by VELCRO®

.

25. The system of claim 21, wherein the underpants are adapted to accept a generally circular-shaped coil over both hips of the patient.
