Abstract

Apparatus for applying Transcranial Magnetic Stimulation (TMS) to an individual, wherein the apparatus comprises: a head mount for disposition on the head of an individual; and a plurality of magnet assemblies for releasable mounting on the head mount, wherein each of the magnet assemblies comprises a permanent magnet, and at least one of (i) a movement mechanism for moving the permanent magnet and/or (ii) a magnetic shield shutter mechanism, for selectively providing a rapidly changing magnetic field capable of inducing weak electric currents in the brain of an individual so as to modify the natural electrical activity of the brain of the individual; wherein the number of magnet assemblies mounted on the head mount, their individual positioning on the head mount, and their selective provision of a rapidly changing magnetic field is selected so as to allow the spatial, strength and temporal characteristics of the magnetic field to be custom tailored for each individual, whereby to provide individual-specific TMS therapy, to assist in diagnosis or to map out brain function in neuroscience research.

First claim

What is claimed is:

1. An apparatus for applying Transcranial Magnetic Stimulation (TMS) to a patient, wherein the apparatus comprises:
a head mount for disposition on the head of the patient; and
a plurality of magnet assemblies mounted on the head mount in a predetermined pattern, wherein each of the magnet assemblies comprises a permanent magnet for selectively providing a rapidly changing magnetic field of 500-5000 Tesla/second, configured to induce electric currents in the brain of the patient, wherein the induced electric currents modify natural electrical activity of the brain of the patient;
wherein the number of magnet assemblies mounted on the head mount, their individual positioning on the head mount, and their selective provision of the rapidly changing magnetic field is selected and configured to allow spatial, strength and temporal characteristics of the rapidly changing magnetic field to be custom tailored for the patient, wherein the custom tailored magnetic field provides a patient-specific TMS therapy at a location in the brain of the patient.

2. The apparatus according to claim 1 comprising a kit of devices, wherein each device comprises a head mount having a plurality of magnet assemblies mounted on the head mount in a predetermined pattern, and further wherein each of the devices in the kit has its respective plurality of magnet assemblies mounted in a different predetermined pattern.

3. The apparatus according to claim 1 , wherein the mechanism for moving the permanent magnet comprises a motor, and further wherein the permanent magnet is attached to a drive shaft of the motor.

4. The apparatus according to claim 1 , wherein the mechanism for moving the permanent magnet comprises a solenoid.

5. The apparatus according to claim 1 , wherein the head mount comprises a skull cap.

6. The apparatus according to claim 1 , wherein the permanent magnet comprises a rare earth magnet.

7. The apparatus according to claim 6 , wherein the rare earth magnet comprises neodymium.

8. A method for providing Transcranial Magnetic Stimulation (TMS) to a patient, the method comprising:
positioning a plurality of magnetic assemblies at selected locations on the head of an individual via a head mount in a predetermined pattern, each of the magnet assemblies including a permanent magnet configured to selectively provide a rapidly changing magnetic field of 500-5000 Tesla/second configured to induce electric currents in a brain of the patient, wherein the induced electric currents modify an electrical activity at a location of the brain; and
rotating the permanent magnets to provide the rapidly changing magnetic field having selected spatial, strength and temporal characteristics custom tailored for the patient, wherein the custom tailored magnetic field provides a patient-specific therapy at the location in the brain of the patient.

9. The method according to claim 8 , wherein the magnet assemblies comprise a mechanism for moving the permanent magnet.

10. The method according to claim 9 , wherein the mechanism for moving the permanent magnet comprises a motor, and further wherein the permanent magnet is attached to a drive shaft of the motor.

11. The method according to claim 9 , wherein the mechanism for moving the permanent magnet comprises a solenoid.

12. The method according to claim 10 , wherein the head mount comprises a skull cap.

13. The method according to claim 8 , wherein the permanent magnet comprises a rare earth magnet.

14. The method according to claim 8 , wherein the rare earth magnet comprises neodymium.
