Abstract

An apparatus and method are provided for treating conditions affecting animal or human subjects. The apparatus and method treat conditions related to abnormal fluid transport, in which treatment is implemented by applying static and dynamic electromagnetic fields to exert pressure on the fluids.

First claim

1 . An apparatus for treating a body part within an animal or human with a condition of impaired flow within the body part, the apparatus comprising:
components for generating a quasi-static magnetic field of generalized direction applied to a body part within a human or non-human animal, and second components for generating electrical currents of generalized direction within the body part, wherein the direction of the electrical currents is not parallel to the direction of the quasi-magnetic field, and a control configured to control the components and second components so that a magnetohydrodynamic force of the quasi-static magnetic field upon the electrical current exerts a pressure on a fluid within the body part.

2 . The apparatus of claim 1 , wherein the components for generating a quasi-static magnetic field or the second components for generating electrical currents include at least one electropermanent magnet.

3 . The apparatus of claim 1 , wherein the components for generating a quasi-static magnetic field or the second components for generating electrical currents include at least one permanent magnet.

4 . The apparatus of claim 1 , wherein the components for generating a quasi-static magnetic field or the second components for generating electrical currents include at least one superconducting magnet.

5 . The apparatus of claim 1 , wherein the second components for generating currents include at least one coil.

6 . The apparatus of claim 1 , wherein the controller applies the transient magnetic field between ten and one million times per second.

7 . A method for treating a body part within an animal or human with a condition of impaired flow within the body part, the method comprising:
generating a quasi-static magnetic field and applying it to the body part, generating electric currents and applying them to the body part, and controlling the generated quasi-static magnetic field and electric currents so that magnetohydrodynamic force of the quasi-static magnetic field upon the electrical currents exerts a pressure on a fluid within the body part that affects transport of the fluid or of body components affected by said transport.

8 . The method of claim 7 , wherein the pressure compensates for impaired flow.

9 . The method of claim 7 , further comprising collecting an image of the body part to form a treatment plan.

10 . The method of claim 7 , further comprising monitoring the quasi-static magnetic field and the electrical currents, or their effects during or immediately after therapeutic pressure application.

11 . The method of claim 7 , further comprising adjusting the quasi-static magnetic field or the electrical currents during therapeutic pressure application.

12 . The method of claim 7 , further comprising adjusting the quasi-static magnetic field or the electrical currents during therapeutic pressure application.

13 . The method of claim 7 , wherein flow transport is augmented to remove pathological accumulations of fluid or of substances that may be transported by said fluid.

14 . The method of claim 7 , wherein flow transport is augmented to remove pathological accumulations of substances in subjects with sleep deficits.
