Abstract

An apparatus and method are provided utilizing electropermanent magnets (EPMs) or other electromagnetic effectors to deliver either or both electrical and changing magnetic fields to rescue the brains or other sections of the nervous system of human or non-human animals that have been subject to acute injury.

First claim

1 . An apparatus for promoting recovery after an acute injury to the central nervous system in a subject comprising:
at least one array of at least one effector in proximity to a lesion in the central nervous system of a subject, wherein the array is configured to generate electrical or magnetic fields in the lesion promptly after acute injury and stimulate neurons or nerves in the central nervous system either within the lesion or connected to the lesion via neuronal pathways.

2 . The apparatus of claim 1 , wherein the effector is an electropermanent magnet.

3 . The apparatus of claim 1 , wherein the effector is an electrode.

4 . The apparatus of claim 1 , wherein the array is configured to create an image of the lesion.

5 . The apparatus of claim 1 , wherein the array defines an extent and magnitude of delivery of electromagnetic fields to the lesion.

5 . The apparatus of claim 1 , wherein the lesion is in the brain.

7 . A method for promoting recovery after an acute injury to the central nervous system in a subject comprising:
generating an electromagnetic field in a lesion via an apparatus with an array of at least one effector promptly after the acute injury to stimulate neurons or nerves in the central nervous system either within the lesion or connected to the lesion via neuronal pathways.

8 . The method of claim 7 , wherein the electromagnetic field is applied within one hour after the acute injury.

9 . The method of claim 7 , wherein the electromagnetic field is applied within four hours after the acute injury.

10 . The method of claim 7 , wherein the electromagnetic field is applied within 72 hours after the acute injury.

11 . The method of claim 7 , wherein a medication is administered to the subject while the electromagnetic field is applied.

12 . The method of claim 7 , where an image of the lesion collected by the apparatus is used in planning the delivery of electromagnetic radiation to the lesion.

13 . The method of claim 7 , wherein the apparatus is used in assessing the delivery of electromagnetic fields to the lesion.

14 . The method of claim 7 , wherein the apparatus is used during transport of the subject.

15 . The method of claim 7 , wherein the apparatus delivers electromagnetic fields to deep lesions.

16 . The method of claim 7 , wherein the apparatus delivers magnetic particles or other magnetically-actuated devices fields to the lesion.

17 . The method of claim 7 , wherein the injury is vascular.

18 . The method of claim 7 , wherein the injury is traumatic.
