Abstract

Apparatus and methods for providing Uni-polar Pulsed Electromagnetic Field (UPEMF) therapy for various medical conditions. The apparatus includes a unit having an electromagnetic field producing coil and a focusing subassembly in it. The coil is arranged to be energized by associated circuitry to produce a pulsating electromagnetic field. The focusing subassembly includes sets of focusing magnets to focus the lines of flux emanating from one pole of the coil so that they are concentrated and extend for some distance generally parallel to the central longitudinal axis of the coil. A Mu metal body is provided around the other pole of the unit and around portions of the focusing magnets.

Claims

1. Apparatus for applying uni-polar magnetic energy to an anatomic region of interest located within the body of a patient, said apparatus comprising a housing, a coil, at least one set of focusing magnets, and a source of electrical energy, said coil being an electrically conductive helical member having a central longitudinal axis, said source of electrical energy being arranged when actuated for providing an electrical signal to said coil to produce a magnetic field having a first pole of a first polarity and a second pole of a second polarity, with said longitudinal axis extending through said poles and with lines of flux extending outward from said first pole, said at least one set of focusing magnets comprising at least two focusing magnets each having a first pole and a second pole, said first pole of each of said focusing magnets being of the same polarity as said first pole of said coil and being disposed adjacent said first pole of said coil on opposite sides of said longitudinal axis to distort lines of flux from said first pole and direct such lines of flux in a path extending generally parallel to said longitudinal axis for a substantial distance for impinging the anatomic region of interest in the body of the patient.

2. The apparatus of claim 1 wherein said apparatus additionally comprises a Mu metal body surrounding said second pole.

3. The apparatus of claim 1 wherein said apparatus additionally comprises a Mu metal body surrounding said second poles of said focusing magnets.

4. The apparatus of claim 2 wherein said apparatus additionally comprises a Mu metal body surrounding said second poles of said focusing magnets.

5. The apparatus of claim 1 wherein each of said focusing magnets is a permanent magnet.

6. The apparatus of claim 1 wherein each of said focusing magnets is an electromagnet.

7. The apparatus of claim 1 wherein said apparatus includes at least two sets of focusing magnets, each set of focusing magnets comprising at least two focusing magnets each having a first pole and a second pole, wherein a first set of said focusing magnets is located closer to said first pole of said coil than a second set of said focusing magnets, said first poles of said at least two focusing magnets of said first set being disposed on opposite sides of said longitudinal axis a first predetermined distance from said longitudinal axis, said first pole of said at least two focusing magnets of said second set being disposed on opposite sides of said longitudinal axis a second predetermined distance from said longitudinal axis, said second predetermined distance being less than said first predetermined distance.

8. The apparatus of claim 7 wherein each of said focusing magnets of said first set is stronger than each of said focusing magnets of said second set.

9. The apparatus of claim 2 wherein said apparatus includes at least two sets of focusing magnets, each pair of focusing magnets comprising at least two focusing magnets each having a first pole and a second pole, wherein a first set of said focusing magnets is located closer to said first pole of said coil than a second set of said focusing magnets, said first poles of said at least two focusing magnets of said first set being disposed on opposite sides of said longitudinal axis a first predetermined distance from said longitudinal axis, said first pole of said at least two focusing magnets of said second set being disposed on opposite sides of said longitudinal axis a second predetermined distance from said longitudinal axis, said second predetermined distance being less than said first predetermined distance.

10. The apparatus of claim 9 wherein each of said focusing magnets of said first set is stronger than each of said focusing magnets of said second set.

11. The apparatus of claim 1 wherein said source of electrical energy comprises an electrical circuit coupled to said coil which when actuated causes said coil to produce a pulsed electromagnetic field.

12. The apparatus of claim 2 wherein said source of electrical energy comprises an electrical circuit coupled to said coil which when actuated causes said coil to produce a pulsed electromagnetic field.

13. A method of treating medical condition of a patient by applying a pulsed uni-polar electromagnetic field to a region of interest in the body of the patient, said method comprising:

a) providing apparatus comprising a housing, a coil, at least one set of focusing magnets, and a source of electrical energy, said coil being an electrically conductive helical member having a central longitudinal axis, said at least one set of focusing magnets comprising at least two focusing magnets each having a first pole of a first polarity and a second pole of a second polarity;
