Transcranial magnetic stimulation system and methods
First Claim
1. A coil for magnetic stimulation of a target area, the coil positionable on a body part, the coil comprising:
- a base portion comprising at least one member for providing electrical current flow in a direction tangential to the target area, said base portion positioned at a first level with respect to the target area;
a protruding return portion for carrying returning current in a direction opposite the direction of current flow of said base portion member, said protruding return portion in electrical communication with said at least one member and positioned at a second level with respect to the target area, the second level located at a distance above the first level; and
a contacting return portion for carrying returning current in a direction opposite the direction of current flow of said base portion member, said contacting return portion in electrical communication with said at least one member and positioned substantially in the first level and spaced at a distance from the target area.

Abstract
A system and methods for transcranial magnetic stimulation, the system including a helmet, a positioning portion, a stimulator and a cooling system, are disclosed. The helmet includes a coil for deep brain magnetic stimulation. The coil has a base portion, and return portions, which may include a protruding return portion and a contacting return portion. The coil is designed to minimize unintended stimulation of portions of the brain, while reducing accumulation of surface charges. The coil is stimulated at several locations and/or at different times so as to focus the electrical field on a specific deep neuronal structure.
