Magnetic core for medical procedures
The inventive technique includes a system, method and device for treating a patient. The device includes a magnetic device having a core created by a binder process having a relatively low temperature. The device further includes a conductor in electrical communication with the core.
1. A device for transcranial magnetic stimulation (TMS), the device comprising:
a magnetic core comprising a ferromagnetic material that comprises ferromagnetic particles that are substantially insulated from each other, the magnetic core created by compressing the ferromagnetic material; and
a conductor in electrical communication with the core, wherein the conductor is wound around an exterior surface of the magnetic core.
2. The device of claim 1 , wherein the magnetic core has a non-linear shape.
3. The device of claim 1 , wherein the ferromagnetic particles of the magnetic core are combined with an insulative binding material such that the ferromagnetic particles are substantially insulated from each other.
4. The device of claim 1 , wherein the ferromagnetic material is compressed to about 90% of theoretical density or greater.
5. The device of claim 1 , wherein the conductor comprises multiple strands in parallel electrically.
6. The device of claim 1 , wherein the conductor comprises a metal sheet of conductive material.
7. The device of claim 1 , wherein the conductor comprises an extruded magnet wire.
8. The device of claim 1 , wherein the core is shaped into a non-linear form, formed for placement of at least one pole face in proximity to the patient for applying a magnetic field to a target anatomy.
9. The device of claim 1 , wherein the conductor is winding transverse to the core.
10. The device of claim 1 , wherein the ferromagnetic particles of the magnetic core are substantially electrically insulated from each other.
11. The device of claim 1 , wherein the magnetic core has a permeability of greater than 1.
12. The device of claim 1 , wherein the core has at least one pole face.
13. The device of claim 12 , wherein the core is created using the ferromagnetic material by forming the ferromagnetic material into a non-linear core structure, the non-linear core structure formed for placement of the at least one pole face in proximity to the patient for applying a magnetic field to a target anatomy.
14. The device of claim 12 , wherein the at least one pole face comprises a channel cut into the face of the pole with a shorted turn inserted into the channel and connected together outside of the channel.
15. The device of claim 1 , wherein the core includes at least one of the following: iron, nickel, cobalt, and rare earth materials.
16. The device of claim 1 , wherein the conductor is wound around a bobbin structure.
17. The device of claim 16 , wherein the bobbin structure is a single bobbin.
18. The device of claim 16 , wherein the bobbin structure insulates the conductor from the core.
19. The device of claim 1 , wherein the magnetic core is created by compressing the ferromagnetic material such that the magnetic core is rigid.
