Abstract

Claims (41)

1 . A method for treatment of a patient, the method comprising:

providing an applicator to a body part of the patient, the applicator comprising:

an electrode configured to provide a radiofrequency field;

a coil configured to provide a time-varying magnetic field; and

a cavity;

applying the radiofrequency field with a frequency in a range of 0.1 MHz to 300 MHz to the patient to cause heating of the patient;

applying the time-varying magnetic field with a magnetic flux density in a range of 0.2 Tesla to 7 Tesla to the patient to cause stimulation of a muscle of the patient;

repeatedly applying a negative pressure in the cavity to create a vacuum in the cavity to provide a massage to the patient.

2 . The method of claim 1 , wherein the vacuum provides the massage to soft tissue of the body part.

3 . The method of claim 2 , further comprising sucking soft tissue into the cavity.

4 . The method of claim 1 , wherein applying the negative pressure comprises drawing air from the cavity to the applicator.

5 . The method of claim 1 , wherein the electrode is a first bipolar electrode of a bipolar pair of electrodes.

6 . A device for treatment of a patient, the device comprising:

an applicator comprising:

a contact part configured to contact the patient;

an electrode configured to provide a radiofrequency field configured to provide heating to the patient;

a magnetic coil configured to generate a time-varying magnetic field having a magnetic flux density in a range of 0.2 Tesla to 7 Tesla; and

an aperture configured to provide a negative pressure treatment,

wherein the aperture is positioned next to the electrode, and

wherein the negative pressure treatment is configured to provide massage to the patient.

7 . The device of claim 6 , further comprising a vacuum pump.

8 . The device of claim 7 , wherein the vacuum pump is configured to provide a peak pressure in a range of 0.1 kPa to 100 kPa.

9 . The device of claim 6 , wherein the negative pressure treatment comprises drawing air from a cavity below the applicator to the applicator.

10 . The device of claim 6 , wherein the applicator defines a cavity, and the cavity is positioned between the electrode and a surface of the patient.

11 . The device of claim 6 , wherein the applicator further comprises a dielectric material having a stiffness in a range of shore A50 to shore D80.

12 . The device of claim 6 , wherein the electrode is a first bipolar electrode of the bipolar pair of electrodes.

13 . A device for treatment of a patient, the device comprising:

an applicator, comprising:

a contact part configured to contact the patient;

an electrode configured to provide a radiofrequency field;

a magnetic coil configured to generate a time-varying magnetic field having a magnetic flux density in a range of 0.2 Tesla to 7 Tesla; and

an aperture configured to provide a negative pressure,

wherein the radiofrequency field is configured to provide heating to the patient, and

wherein the time-varying magnetic field is configured to cause a muscle contraction to the patient.

14 . The device of claim 13 , further comprising a temperature sensor.

15 . The device of claim 13 , wherein the aperture is configured to provide the negative pressure such that the negative pressure is provided to the tissue under the applicator.

16 . The device of claim 15 , wherein the negative pressure is applied in pulses and wherein each pulse of the pulses of the negative pressure has a pulse duration in a range of 0.1 second to 60 seconds.

17 . The device of claim 13 , further comprising a cavity positioned between the patient and the electrode, wherein the aperture is configured to deliver the negative pressure to the cavity in order to provide the negative pressure to the patient.

18 . The device of claim 13 , wherein the applicator further comprises a dielectric material configured to adapt the applicator to a surface of a body part of the patient.

19 . The device of claim 13 , wherein the magnetic flux density is a peak to peak magnetic flux density.

20 . The device of claim 13 , wherein the device further comprises a vacuum pipe connected to the aperture, and wherein the vacuum pipe is configured to draw air from the cavity to the applicator.
