Abstract:
1. A method for producing a physiological effect in a targeted region of an internal body organ using transcranial magnetic stimulation, the method comprising: providing a system comprising a first and a second electromagnetic coil, a stimulator for stimulating said first and second electromagnetic coils, the stimulator comprising an energy storage device in electrical communication with said first and second electromagnetic coils; a first externally-controllable fast switch in electrical communication with said first electromagnetic coil and said energy storage device; a second externally-controllable fast switch in electrical communication with said second electromagnetic coil and said energy storage device; and an external control unit in electrical communication with said first and second externally-controllable fast switches; positioning said first electromagnetic coil at a first location, said first location in close proximity to a first body part; positioning said second electromagnetic coil at a second location, said second location at a location remote from the body; discharging current to said first and said second electromagnetic coils using said stimulator, wherein said discharging current comprises activating said energy storage device to discharge current into said first electromagnetic coil and to separately discharge current into said second electromagnetic coil wherein said discharging current comprises discharging current only through said first electromagnetic coil at a first time segment and discharging current through said second electromagnetic coil at a second time segment; providing a single, combined current pulse from said discharging of current to said first and second electromagnetic coils, said providing comprising providing a high current flow through said first electromagnetic coil at a first time period and providing a high current flow through said second electromagnetic coil and a low or zero current flow through said first electromagnetic coil at a second time period, wherein said current flow through said second electromagnetic coil leads to re-charge of said energy storage device, thus resulting in said current pulse having a repeatedly monophasic pulse shape; providing an electric field pulse at the targeted region, said electric field pulse resulting from said single, combined current pulse and from said positioning of said first electromagnetic coil and said positioning of said second electromagnetic coil; controlling parameters of said stimulator using said external control unit, wherein said controlling comprises controlling said first and second externally-controllable fast switches and controlling a timing of turning on or off of said first and second externally-controllable fast switches during said provided current pulse; and stimulating the targeted region of the internal body organ using said electric field pulse.
