Title:
MAGNETIC STIMULATION HAVING A FREELY SELECTABLE PULSE SHAPE
Document Type and Number:
WIPO Patent Application WO/2011/083097
Kind Code:
A8
Abstract:
The invention relates to a device and method for generating brief, strong current pulses in a coil, for generating magnetic field pulses, which in accordance with the electromagnetic induction principle cause stimulation currents in the body tissue that trigger an action potential of the nerve and/or muscle cells, wherein the coil can be positioned close to the body tissue to be stimulated, so that the magnetic field thereof permeates the body tissue, and wherein the device comprises a current generating unit, which can generate a freely selectable temporal course of the current through the coil during the current pulse. The invention further relates to a method for determining an optimized temporal course of a brief, strong current pulse through the coil, wherein the temporal course of the current pulse is calculated using a method that numerically simulates the electrical behavior of the nerve and/or muscle cells and of the coil and optimizes the course of the current pulse with respect to at least one parameter, or which optimizes the temporal course of the current pulse with respect to at least one parameter and, based thereon, determines essential characteristic variables of the nerve and/or muscle cells by stimulating the nerve and/or muscle cells with predefined current pulses.
