Aesthetic method of biological structure treatment by magnetic field

A method of applying a time-varying magnetic field to a patient for causing supramaximal muscle contraction, comprising:

• causing a treatment device to generate the time-varying magnetic field,
• wherein the treatment device comprises:
• an energy storage device;
• a first applicator including a first magnetic field generating device;
• and
• a second applicator including a second magnetic field generating device;
• placing the applicators in contact with the patient's skin or clothing at a body region;
• discharging the energy storage device to the magnetic field generating devices, each thereby generating an impulse of a time-varying magnetic field, the impulse comprising magnetic flux density in a range of 0.5 T to 7 T;
• stopping discharging of the energy storage device after the impulse of the time-varying magnetic fields in order to establish a magnetic pulse;
• applying the time-varying magnetic fields to muscles within the body region, wherein the body region includes at least one of a thigh, buttocks, abdomen, hips, or arm in the form of a first train and a second train, wherein each of the trains include a plurality of magnetic impulses of the time-varying magnetic fields, respectively,
• wherein the first train and the second train comprise magnetic impulses having a repetition rate in a range of 2 Hz to 90 Hz,
• wherein the first train includes a first repetition rate of the magnetic impulses and the second train includes a second repetition rate of the magnetic impulses, and
• wherein the first repetition rate differs from the second repetition rate.

A method of applying a time-varying magnetic field for toning or firming muscle in a body region, comprising:

• charging an energy storage device having a capacitance in a range of 5 nF to 100 mF;
• discharging energy from the energy storage device to a magnetic field generating device in order to generate the time-varying magnetic field with a magnetic flux density in a range of 0.5 T to 7 T, with an impulse duration in a range of 3 μs to 3 ms, and with a repetition rate up to 700 Hz, wherein the magnetic field generating device has a total magnetic field generating device surface of up to 8000 cm2;
• contacting an applicator including the magnetic field generating device to the body region, the body region including at least one of a buttock, abdomen, or hips;
• and
• cooling the body region with a cooling element, the cooling element having a temperature between 10° C. and −15° C.,
• wherein the applicator is coupled to the patient by a length-adjustable belt;
• and
• applying the time-varying magnetic field to the body region to cause a muscle contraction of a muscle, wherein the muscle includes at least one of a gluteus maximus muscle, a gluteus medius muscle, a gluteus minimus muscle, a rectus abdominis muscle, a latissimus dorsi muscle, an abdominal internal oblique muscle, an abdominal external oblique muscle, a transverse abdominal muscle, or a pyramidalis muscle.

A method for toning or firming at least one muscle in a body region of a human using a treatment device which generates a plurality of pulses of time-varying magnetic fields, comprising:

• placing a first magnetic field generating device and a second magnetic field generating device proximate to the body region, wherein the body region comprises gluteal muscles;
• generating a time-varying magnetic field by each of the first and the second magnetic field generating device, each of the time-varying magnetic fields having a magnetic flux density in a range of 0.1 Tesla to 7 Tesla, and a maximal value of a magnetic flux density derivative of between 0.5 kT/s and 400 kT/s;
• and
• simultaneously applying the time-varying magnetic fields, generated by the first and the second magnetic field generating devices, to gluteal muscles in order to cause a contraction of the gluteal muscles.
