Abstract

Apparatus for applying Transcranial Magnetic Stimulation (TMS) to a patient, the apparatus including a head mount for disposition on the head of a patient; and a plurality of magnet assemblies for releasable mounting on the head mount, wherein each of the magnet assemblies includes a magnet for selectively providing a rapidly changing magnetic field capable of inducing weak electric currents in the brain of a patient so as to modify the 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 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 patient, whereby to provide patient-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 magnet for selectively providing a rapidly changing magnetic field of 500-5000 Tesla/second, corresponding to a magnet movement speed of no less than 400 Hertz, configured to induce electric currents in the brain of the patient so as to 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 so as to allow the spatial, strength and temporal characteristics of the rapidly changing magnetic field to be custom tailored for the patient, whereby to provide patient-specific TMS therapy, to assist in diagnosis or to map out brain function in neuroscience research.

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 magnet assemblies comprise a permanent magnet and apparatus for moving the permanent magnet.

4. The apparatus according to claim 1 , wherein the magnet assemblies comprise an electromagnet.

5. A method for providing Transcranial Magnetic Stimulation (TMS) to a patient, the method comprising:
providing an apparatus comprising:
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 magnet for selectively providing a rapidly changing magnetic field of 500-5000 Tesla/second, corresponding to a magnet movement speed of no less than 400 Hertz, configured to induce electric currents in the brain of the patient so as to modify natural electrical activity of the brain of the patient;

positioning the head mount on the head of the patient; and
selectively providing the rapidly changing magnetic field with at least one of the magnet assemblies;
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 so as to custom tailor the spatial, strength and temporal characteristics of the rapidly changing magnetic field for that patient, whereby to provide patient-specific TMS therapy, to assist in diagnosis or to map out brain function in neuroscience research.

6. The method according to claim 5 , wherein the magnet assemblies comprise a permanent magnet and apparatus for moving the permanent magnet.

7. The method according to claim 1 , wherein the magnet assemblies comprise an electromagnet.
