Abstract
A transcranial magnetic stimulation coil which is location-specific for frontal lobe regions, occipital lobe regions, parietal lobe regions, right temporal regions and left temporal regions is designed with multiple spaced apart stimulating elements having current flow in a substantially circular direction, and multiple return elements having current flow in substantially the same circular direction.
Claims17
A coil for magnetic stimulation of a body part, the coil comprising:
- a base portion including multiple stimulating elements wherein said multiple stimulating elements include a first stimulating element and a second stimulating element adjacent to said first stimulating element, and a third stimulating element adjacent to said second stimulating element, said base portion configured to encircle at least a portion of a first section of a body part and to provide electrical flow in a clockwise or counter-clockwise path;
- and
- a protruding return portion including multiple protruding return elements wherein each of said multiple protruding return elements is continuous with and positioned at an angle of between 90 and 180 degrees to each of said multiple stimulating elements, wherein said multiple protruding return elements include a first return element and a second return element adjacent to said first return element, and a third return element adjacent to said second return element, said protruding return portion configured to encircle and protrude from, wherein said second section is in a different location than said first section, and to provide electrical flow in a continuation of the clockwise or counter-clockwise path of said base portion, wherein all of said multiple stimulating elements of said base portion are configured to contact the body part and wherein all of said multiple protruding return elements are configured to protrude from the body part, wherein said coil does not include any contacting return elements.
A coil for magnetic stimulation of a body part, the coil comprising:
- a base portion including multiple stimulating elements wherein said multiple stimulating elements include a first stimulating element and a second stimulating element adjacent to said first stimulating element, and a third stimulating element adjacent to said second stimulating element, said base portion configured to encircle at least a portion of a first section of a body part, said base portion having a first base portion side and a second base portion side and a length from said first base portion side to said second base portion side, said first base portion side configured to be positioned on a first side of said first section of a body part, and second base portion side configured to be positioned on a second side of said first section of a body part, wherein each of the multiple stimulating elements is positioned across the length from said first base portion side to said second base portion side;
- and
- a protruding return portion including multiple protruding return elements wherein each of said multiple protruding return elements is positioned at an angle of between 90 and 180 degrees to each of said multiple stimulating elements, wherein said multiple protruding return elements include a first return element and a second return element adjacent to said first return element, and a third return element adjacent to said second return element, said protruding return portion configured to encircle and protrude from a second section of the body part, wherein said second section is in a different location than said first section, wherein all of said multiple stimulating elements of said base portion are configured to contact the body part and wherein all of said multiple protruding return elements are configured to protrude from the body part;
- and wherein said coil does not include any contacting return elements;
- and
- multiple first side connecting elements positioned on said first base portion side and multiple second side connecting elements positioned on said second base portion side, said multiple first side connecting elements configured to carry electrical flow from said first base portion side to said return portion and said multiple second side connecting elements configured to carry electrical flow from said return portion to said second base portion side wherein all of said connecting elements are configured to contact the body part.

A method of treating a disease, the method comprising:
- placing a circular coil on a body part, said circular coil including a base portion having parallel adjacent multiple stimulating elements, said base portion configured to encircle at least a portion of a first section of the body part and to provide electrical flow in a circular path, and a protruding return portion having parallel adjacent multiple protruding return elements, wherein each of said multiple protruding return elements is continuous with and positioned at an angle of between 90 and 180 degrees to each of said multiple stimulating elements, said protruding return portion configured to encircle and protrude from at least a portion of a second section of the body part, wherein said second section is in a different location than said first section, and provides electrical flow in a continuation of the circular path of said base portion;
- wherein all of said multiple stimulating elements of the circular coil are positioned to be in direct contact with the body part while all of said multiple return elements of the circular coil are positioned to protrude from the body part;
- and
- stimulating the body part using said circular coil.
