Abstract
The disclosure relates to devices and methods for applying a magnetic field on a body of a patient. The time-varying magnetic field may applied to a brain of the patient. The disclosure provides a method of finding the position suitable for application of the magnetic field to the brain. The devices and methods of the disclosure may be suitable for reducing of food craving.
Claims30
A device for generating a time-varying magnetic field, the device comprising:
- a positioning arm;
- a main body comprising:
- an energy source;
- an energy storage device configured to be charged by the energy source;
- and
- a switching device configured to be switched to discharge energy from the energy storage device to a magnetic field generating device to generate an impulse of the time-varying magnetic field;
- a connecting tube configured to connect an applicator to the main body;
- and
- the applicator, the applicator comprising:
- the magnetic field generating device;
- a rear side proximate to the connecting tube and a front side less proximate to the connecting tube than the rear side;
- a left side and a right side, wherein the right side and the left side are both adjacent to the front side and the rear side, and wherein the right side is opposite to the left side;
- a lower side configured to be positioned to a patient;
- an upper side configured to be positioned less proximate to the patient than the lower side, wherein the upper side comprises:
- a left visual element proximate to the left side and less proximate to the right side, and wherein the left visual element is proximate to the front side;
- a right visual element proximate to the right side and less proximate to the left side, and wherein the right visual element is less proximate to the front side than the left visual element;
- and
- a center visual element proximate to the front side and less proximate to the rear side, wherein the applicator is configured to be positioned to the patient such that:
- the left visual element is aligned with a first anatomical structure and the center visual element is aligned towards a second anatomical structure on the patient's right side, or
- the right visual element is aligned with the first anatomical structure and the center visual element is aligned towards the second anatomical structure on the patient's left side,
- wherein the first anatomical structure is different from the second anatomical structure.
