Abstract
The present invention relates to apparatus and methods for stimulation and/or treatment of neural structure by high power time-varying magnetic field. The stimulation is followed by at least modulation of action potential of neural structure. The apparatus and methods may be used e.g. in physiotherapy, psychotherapy, psychiatry or addiction treatment.
Claims32
A method of stimulating a patient's neural structure using a time-varying magnetic field, comprising:
- inducing an action potential and/or modulating the action potential, with the time-varying magnetic field applied into the neural structure and having a repetition rate exceeding at least 120 Hz;
- and wherein the neural structure is a peripheral neural system, spinal cord and/or a deep neural structure.
(canceled)
A method of stimulating a patient's neural structure with a time-varying magnetic field inducing an action potential and/or modulating the action potential, comprising:
- exposing the patient to a magnetic flux density of a time-varying magnetic field exceeding a value of 2 T and/or a repetition rate of the stimulation exceeding 100 Hz;
- wherein the method provides at least one of:
- a) treating of a neurodegenerative disease,
- b) inducing at least partial muscle contraction, and/or
- c) myorelaxative effect.
(canceled)
A method of stimulating a patient's neural structure using a time-varying magnetic field inducing an action potential and/or modulating the action potential, comprising:
- exposing the patient to a time-varying magnetic field with a repetition rate which exceeds a repetition rate resolution of the stimulated neural structure and wherein the time-varying magnetic field generates an envelope including at least two pulses.
A method of stimulating a patient's neural structure with a time-varying magnetic field inducing an action potential and/or modulating the action potential, comprising exposing the patient's neural structure to a magnetic flux density of the time-varying magnetic field wherein an amplitude of the magnetic flux density, an impulse duration and/or a repetition rate varies in time.
