1. A method for treating pelvic floor issues of a patient using a time-varying magnetic field applied to a pelvic floor of the patient wherein the time-varying magnetic field is applied to a muscle and/or a nerve innervating the muscle within a body region between coccyx and pubic bone of the patient in order to cause a contraction of the muscle in the pelvic floor, the magnetic field generated by a treatment device which includes a switching device, an energy storage device and a magnetic field generating device, comprising:

  • a) charging the energy storage device;

    b) switching the switching device on for a first time period having a duration in a range of 3 to 1000 μ

    s and enabling a current discharge from the energy storage device to the magnetic field generating device in order to generate an impulse of the time-varying magnetic field and applying the impulse of the time-varying magnetic field to the patient;

    c) switching the switching device off for a second time period at least four times longer than the first time period and generating no magnetic field by the magnetic field generating device;

    d) repeating steps a)-c) for a third time period having a duration in a range of 5 to 500 ms in order to generate a first train of pulses wherein each pulse consists of the impulse of the time-varying magnetic field and the second time period;

    e) switching the switching device off after the third time period for a fourth time period having a duration in a range of 10 to 1200 ms and generating no magnetic field;

    f) repeating steps a)-e) at least once during a fifth time period having a duration in a range of 3 to 120 seconds;

    g) repeating steps a) and b) and switching the switching device off for a sixth time period at least nine times longer than the first time period and different from the second time period;

    h) repeating step g) for a seventh time period having a duration in a range of 1.5 to 6 seconds in order to generate a second train of pulses of the time-varying magnetic field wherein the second train of pulses differs from the first train of pulses and wherein the seventh time period consists of first, second, and third subperiods each having a duration in a range of 0.5 to 2 seconds;

    wherein an amplitude of a magnetic flux density of each subsequent magnetic pulse of the second train of pulses increases to a predetermined magnetic flux density value during the first subperiod;

    wherein the amplitude of the magnetic flux density of each subsequent magnetic pulse of the second train of pulses maintains the predetermined magnetic flux density value during the second subperiod; and

    wherein the amplitude of the magnetic flux density of each subsequent pulse of the second train of pulses decreases during the third subperiod from the predetermined magnetic flux density value;

    i) switching the switching device off after the seventh time period for an eighth time period having a duration in a range of 1 to 5 seconds and generating no magnetic field by the magnetic field generating device; and

    j) repeating steps g)-i) at least once during a ninth time period having a duration of at least 30 seconds.
