Abstract

In a method for stimulation and treatment of a biological structure of a patient, the biological structure is treated by high power time-varying magnetic field. The treatment is followed by at least a partial muscle contraction. The method may be used in applications for non-invasive aesthetic medicine.

Claims

1. A method for toning and/or strengthening a muscle of a patient using a treatment device including a connection to energy source, a switching device enabling repetitively generating a magnetic field, and an energy storage device connected to a magnetic field generating device, comprising:

a. charging the energy storage device to provide energy to the magnetic field generating device;

b. applying a single pulse of a time-varying magnetic field to the muscle of the patient;

wherein the time-varying magnetic field causes a contraction of the muscle; and

wherein energy loss between any of successive amplitudes of the time-varying magnetic field is not higher than 21%.

2. The method of claim 1 wherein an impulse duration of the time-varying magnetic field is up to 900 μ

s.

3. The method of claim 2 wherein a magnetic flux density of the time-varying magnetic field is at least 0.2 T;

and

wherein a repetition rate of the impulses of the time-varying magnetic field is up to 100 Hz.

4. The method of claim 1 wherein the method further comprises repetitively switching the switching device on.

5. The method of claim 1 wherein the switching device is in a parallel connection to the energy source.

6. The method of claim 1 wherein the treatment device has a power consumption below 1.3 kW.

7. A method for reducing cellulite of a patient using a device including a connection to an energy source, a switching device, an energy storage device and a magnetic field generating device comprising:

a. providing energy from the energy storage device to the magnetic field generating device in order to generate a time-varying magnetic field;

b. applying the time-varying magnetic field to the patient;

c. cooling the magnetic field generating device;

d. repetitively switching the switching device on in order to generate the magnetic field;

wherein an impulse duration of the time-varying magnetic field is up to 900 μ

s; and

wherein an energy loss between any successive amplitudes of the time-varying magnetic field is not higher than 21%.

8. The method of claim 7 wherein the magnetic field generating device is within a casing;

and

wherein the casing is in actual contact with the patient.

9. The method of claim 7 wherein the energy storage device is in serial connection with the magnetic field generating device.

10. The method of claim 7 wherein the method further comprises controlled shorting of the energy source.

11. The method of claim 7 wherein the method further comprises generating the magnetic field with a magnetic flux density of at least 0.15 T;

and

applying the time-varying magnetic field with a repetition rate of at least 1 Hz.
