AESTHETIC METHOD OF BIOLOGICAL STRUCTURE TREATMENT
`
`BY MAGNETIC FIELD
`
`FIELD OF THE INVENTION
`
`[0001]
`
`The present invention generally relates to device and methods using the influence of magnetic and
`
`induced electric field on biological structure. The magnetic field is time-varying and high powered therefore the
`
`method is based on a value of magnetic flux density sufficient to induce at least muscle contraction. The invention
`
`proposesfurther to combine the magnetic field with radiofrequency,light, mechanical or pressure sourcein order to
`
`provide an apparatus for improved treatment.
`
`BACKGROUND OF THE INVENTION
`
`[0002]
`
`Aesthetic medicine includes all treatments resulting in enhancing a visual appearance and
`
`satisfaction of the patient. Patients want to minimize all imperfections including body shape and effects of natural
`
`aging. Indeed, patients request quick, non-invasive proceduresproviding satisfactory results with minimal risks.
`
`[0003]
`
`The most common methods usedfor non-invasive aesthetic applications are based on application
`
`of mechanical waves, e.g. ultrasound or shock wave therapy; or electromagnetic waves, e.g. radiofrequency
`
`treatmentor light treatment, such as intense pulsedlight or laser treatment. The effect of mechanical waves on tissue
`
`is based especially on cavitation, vibration and/or heat
`
`inducing effects. The effect of applications using
`
`electromagnetic wavesis based especially on heat production in the biological structure. However the currently used
`
`treatment methods are used separately.
`
`[0004]
`
`A mechanical treatment using mechanical waves and/or pressure were used for treatment of
`
`cellulite or adipose cells. However, mechanical treatment includes several drawbacks such as risk of a panniculitis
`
`and/or non-homogenous result.
`
`[0005]
`
`A thermal treatment is applied to the patient for enhancing a visual appearanceof the skin by e.g.
`
`increasing production of collagen and/or elastin, smoothing the skin or reduction of cellulite and/or adipose cell.
`
`However, thermal treatment includes several drawbacks such as risk of overheating a patient or even causing a
`
`thermal damage to the patient, risk of a panniculitis and/or non-homogenous result.
`
`[0006]
`
`The mechanical and/or the thermal treatment is not able to provide enhanced visual appearance
`
`of a muscle, e.g. muscle shaping, toning and/or volumization effect. Mechanical treatment and/or the thermal
`
`treatment includes several drawbacks suchasrisk of a panniculitis, non-homogenousresult and others.
`
`[0007]
`
`Current magnetic methods are limited in key parameters which do not allow satisfactory
`
`enhancement of visual appearance. As a result, new methods are needed to enhancethe visual appearanceof the
`
`patient.
`
`[0008]
`
`Existing devices have low efficiency and they waste energy, which limits their use. Eddy currents
`
`induced within the magnetic field generating device create engineering challenges. Existing devices contain magnetic
`
`field generating devices which are made of metallic strips, electric wires or hollow conductors. Since the therapy
`
`requires large currents, significant losses are caused by induced eddy currents within the magnetic field generating
`
`device. Eddy currents lead to production of unwanted heat and therefore there is need to sufficiently cool the
`
`magnetic field generating device. Also, the energy source must be protected during reverse polarity of resonance.
`
`This requires using protective circuits which consumesignificant amounts of energy. Skin tissue is composed of
`
`three basic elements: epidermis, dermis and hypodermis or so called subcutis. The outer and also the thinnest layer
`
`of skin is the epidermis. The dermis consists of collagen, elastic tissue and reticular fibers. The hypodermis is the
`
`lowestlayer of the skin and containshair follicle roots, lymphatic vessels, collagen tissue, nerves and also fat forming
`
`

`

`a subcutaneous white adipose tissue (SWAT). The adipose cells create lobules which are bounded by connective
`
`tissue, fibrous septa (retinaculum cutis).
`
`[0009]
`
`Another part of adiposetissue, so called visceral fat, is located in the peritoneal cavity and forms
`
`visceral white adipose tissue (VWAT) located between parietal peritoneum and visceral peritoneum, closely below
`
`muscle fibers adjoining the hypodermis layer.
`
`[0010]
`
`The currently used aesthetic applications don’t provide any treatment combining the effect of time-
`
`varying magnetic field treatment and an auxiliary treatment method, e.g. treatment by thermal treatment and/or
`
`mechanical
`
`treatment. The currently used thermal
`
`treatment
`
`includes many adverse events such as non-
`
`homogenous temperature distribution, panniculitis,
`
`insufficient blood and/or lymph flow during and/or after the
`
`treatment. Additionally several adverse event such as panniculitis may occur after the treatment. Further the
`
`treatment maybe painful so that a topical anesthetic is recommended.
`
`[0011]
`
`The development of new aesthetic treatment methods providing improved results in shorter time
`
`periods is needed.
`
`SUMMARYOF THE INVENTION
`
`[0012]
`
`The treatment methods and devices as described below produce a time varying magnetic field for
`
`patient treatment which better optimizes energy use, increases the effectiveness of the treatments and provide a
`
`new treatment. The magnetic impulses may be generated in monophasic, biphasic or polyphasic regimes. Inafirst
`
`aspect, the device has one or more magnetic field generating devices; a switch; an energy storage device and a
`
`connection to an energy source. The magnetic field generating device may be made of wires, more preferably
`
`individually insulated wires wherein a conductor diameter is less than 20 mm, preferably less than 10 mm, more
`
`preferably less than 3 mm, even more preferably less than 0.5 mm and the most preferably less than 0.05 mm.
`
`Smaller diameter and individual
`
`insulation of the wires significantly reduces self-heating of the magnetic field
`
`generating device and therefore increase efficiency of magnetic treatment device. The magnetic field generating
`
`device maybe flexibly attached in a casing of device. The casing may comprise a blower or blowers which ensure
`
`cooling of the magnetic field generating device.
`
`[0013]
`
`The present methods provide new aesthetic applications for focused remodeling of the patient’s
`
`body. The magnetic field generating device of the magnetic treatment device may beflexibly attached to casing of
`
`the device. The blower or blowers may be arranged to blow air on both sides of magnetic field generating device.
`
`Optionally, the magnetic field generating device maybea flat type magnetic field generating device.
`
`[0014]
`
`The new magnetic treatment methods may improve a muscle of the patient. Further the new
`
`magnetic treatment method enables improved treatment results. Alternatively the magnetic treatment may provide
`
`pain relief and/or myorelaxation effect to the patient.
`
`[0015]
`
`The method of treating a biological structure uses a combination of non-invasive methods for
`
`enhancing human appearance. The invention utilizes electromagnetic field. Methods may be used for targeted
`
`remodeling of adipose tissue, focused treatment of cellulite, body contouring, skin tightening or skin rejuvenation.
`
`The invention relates to focused heating of the target tissue by electromagnetic waves, whereasthe effect of focused
`
`heating of the target tissue is amplified by the effect of a magnetic treatment.
`
`[0016]
`
`The time-varying magnetic field induces the muscle contraction at higher repetition rates and the
`
`contraction is stronger. The treatment ma be moreefficient for reducing the number and/or volume of adipocytes and
`
`enhancing the visual appearanceof the treated body region via targeted muscle contraction. Further the temperature
`
`homogeneity of is improved. Additionally, strong muscle contractions at higher repetition rates cause mechanical
`
`movementofall the layers in proximity of the contracted muscle. The methods therefore cause remodeling and/or
`
`neogenesis of the collagen and elastin fibers.
`
`

`

`[0017]
`
`The methods enable new treatments by magnetic and/or electromagnetic field. The repetition rate
`
`of the magnetic field is in the range of 1 to 300 Hz with high magnetic flux density up to 7 Tesla (equivalent to 70000
`
`Gauss). The frequency of the electromagnetic field is 13.56 or 40.68 or 27.12 MHz or 2.45 GHz.
`
`[0018]
`
`On the other hand, a combination with a magnetic treatment method may enhance the visual
`
`appearance of the muscle and/or other soft tissue such as skin or adipose tissue, including increase of apoptotic
`index.
`
`[0019]
`
`The methods enable combined treatment using different treatment methods such as magnetic
`
`and/or auxiliary treatment methods. The combination of different treatment methods provide a complex treatment
`
`method for focused treatment of a treated body region.
`
`[0020]
`
`The present methods provide combined treatment using influence of magnetic treatment and
`
`mechanical
`
`treatment by shock waves, ultrasound waves, acoustic waves and/or pressure application. The
`
`mechanical treatment may induce mechanical damage to the treated biological structure and/or tissues. Ultrasound
`
`waves mayheat adipose cells, dermis, hypodermis or other target biological structure. Ultrasound waves may also
`induce a cavitation.
`
`[0021]
`
`The present methods and devices may include a handheld applicator, for manual and precise
`
`treatmentof tissue, particularly of uneven areas, and scanning unit providing automated or manual positioning of the
`
`optical spot created by the optical waves (for example light) on the tissue of a subject for homogenoustreatment of
`
`large areas of tissue. In some embodiments, the handheld applicator may be connected to the scanning unit by an
`
`attaching mechanism whichin turn provides the handheld applicator with optical treatment. The handheld applicator
`
`may apply optical waves onto the tissue of the subject to be scanned during treatment.
`
`[0022]
`
`Present method and devices mayalso include sensors configured to measure various parameters
`
`of the scanning unit and the subject tissue. Based on the information from the at least one sensor a controller
`
`connected to scanning unit may change parameters of the optical treatment system and method, including but not
`
`limited to the optical output, the duration of treatment, the optical spot size or shape, the scanning speedor direction
`
`of movement of the optical spot, the wavelength or wavelengths of the optical waves, the frequency, or optical flux
`
`density. Such a change may provide more homogenous treatment or may protect the patient from discomfort or
`harm.
`
`[0023]
`
`The present method provides combined treatment using magnetic treatment and thermal
`
`treatment. A combination of heating/cooling may cause an increase in apoptotic index, increase in muscle thickness,
`
`apoptosis and/or necrosis of the target biological structure such as adipose cells. Remodeling of the target biological
`
`structure is more significant and treatment duration is reduced. Potential risks for the patient associated with single
`
`treatment methods are avoided. Further the side effects such as swelling and/or inflammation are reduced and/or
`eliminated.
`
`[0024]
`
`Although methods of the present invention may be described herein as a sequenceof steps ina
`
`particular order,
`
`it is understood that, unless explicitly stated otherwise, the steps of any methods of the present
`
`invention may alternatively be performed in a different order.
`
`In some embodiments, someor all of the steps of a
`
`method of the present invention may be repeated.

`
`Throughoutthis disclosure, various aspects of the invention can be presentedin a range format. It
`
`should be understood that the description in range format is merely for convenience and brevity and should not be
`
`construed as an inflexible limitation on the scope of the invention. Accordingly, the description of a range should be
`
`considered to have specifically disclosed all the possible subranges as well as individual numerical values within that
`
`range. For example, description of a range such as from 1 to 6 should be considered to have specifically disclosed
`
`subranges suchasfrom 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6 etc., as well as individual
`
`numberswithin that range, for example, 1, 2, 2.7, 3, 4, 5, 5.3, 6 and any whole and partial increments therebetween.
`
`This applies regardless of the breadth of the range.
`
`[0076]
`
`Figure 1 illustrates a cross section of winding of a magnetic field generating device for a magnetic
`
`treatment device. The magnetic field generating device may be constructed from litz-wire, wherein each wire is
`
`insulated separately. Each individual conductor is coated with non-conductive material so the magnetic field
`
`generating device constitutes multiple insulated wires. Unlike existing magnetic field generating device conductors,
`
`the present magnetic field generating device is not made of bare wire e.g. litz-wire without insulation, or conductive
`
`tapes, conductive strips, or copper pipe with hollow inductors. The insulation of wires separately is a substantial
`
`improvement, since this leads to a significant reduction of the induced eddy currents. Power loss due to eddy
`
`currents, per single wire,
`
`is described by Equation 1 below. The small diameter of wires significantly reduces self-
`
`heating of the magnetic field generating device and therefore increases efficiency of the present magnetic treatment
`device.
`
`Peppy =
`
`rr B; .d? f°
`6-k-p-D
`
`>
`
`Eq. 1
`
`[0077]
`
`where:
`
`Peppy is power loss per unit mass (W-kg"'); Bp is the peak of magnetic field (1); fis
`
`frequency (Hz); d is the thickness of the sheet or diameter of the wire (m); & is constant equal to 1 for a thin sheet
`
`and 2 for a thin wire; p is the resistivity of material (Q-m); D is the density of material (kg-m*).
`
`[0078]
`
`The individual insulation of each wire reduces eddy currents. The individually insulated wires may
`
`be wound either one by one or in a bundle ofindividually insulated wires so as to form a magnetic field generating
`
`device, which will serve as a magnetic field generator. The magnetic field generating device provides an improvement
`
`in the efficiency of energy transfer in the LC resonant circuit and also reducesor eliminates unwanted thermal effects.
`
`[0079]
`
`The magnetic field generating device may have a planar magnetic field generating device shape
`
`wherethe individually insulated wires may have cross-section wires with conductor diameter less than 20, 10, 5, 3,
`
`1, 0.5 or 0.05 mm. The wires are preferably made of materials with higher density and higher resistivity e.g. gold,
`
`platinum or copper. The diameters of the single wires should be minimal. On the other hand the total diameter should
`
`be maximal because of inverse proportion between the cross-section of all wires forming the magnetic field
`
`generating device and the electrical resistance. Therefore the ohmic part of the heat is then lower. Eq. 2 describes
`
`power loss of the magnetic field generating device:
`
`

`

`_
`P,=
`
`S
`m
`
`Eq. 2
`
`[0080]
`
`Where:
`
`Pp is the power loss heat dissipation (VV);p is the resistance (QO-m); / is the length
`
`of wire (m); S is the surface area (m2);
`
`/is the current (A) and mis 1 kg of wire material.
`
`[0081]
`
`Total power loss is (Eq.3):
`
`Pror = Peppy +P.
`
`Eq. 3
`
`[0082]
`
`Where: Provis the total power losses (W-kg"'); Peppy is the power dissipation of eddy currents
`
`(W-kg"'); Pris the power loss heat dissipation (W-kg").
`
`[0083]
`
`Dynamic forces produced by current pulses passing through the wires of the magnetic field
`
`generating device cause vibrations and unwanted noise. The individual
`
`insulated wires of the magnetic field
`
`generating device may be impregnated under pressure so asto eliminate air bubbles between the individual insulated
`
`wires. The space between wires can befilled with suitable material which causes unification, preservation and electric
`
`insulation of the system. Suitable rigid impregnation materials like resin, and elastic materials like PTE can be also
`
`used. With the magnetic field generating device provided as a solid mass, the vibrations and resonance caused by
`
`movements ofthe individual insulated wires are suppressed. Therefore noise is reduced.
`
`[0084]
`
`The magnetic field generating device may be attached to the case of the applicator, such as a
`
`hand held applicator of the magnetic treatment device; build-in applicator in e.g. chair, bed; or stand-alone applicator
`
`e.g. on mechanical fixture. The hand held applicator mayinclude a display unit for controlling the magnetic treatment
`
`device. Alternatively the display unit may display treatment parameters such as a repetition rate, a magnetic flux
`
`density or lapsed time of the treatment. The magnetic treatment device may preferably include a human machine
`
`interface (HMI) for displaying and/or adjusting the treatment parameters. The HMI mayinclude at least one button,
`
`knob, slide control, pointer or keyboard. Alternatively the HMI mayinclude a touchscreen, an audio-visual input/output
`
`device such as PC including display unit, an input unit and/or a graphical user interface.
`
`[0085]
`
`The mechanical fixture may be rigid with the applicator hanging on the rigid mechanical fixture.
`
`Alternatively the mechanical fixture may be articulated. The mechanical fixture may include at least one joint to enable
`
`tailor made position of the applicator. The attachment may be provided by an elastic material e.g., silicone, gum; or
`
`other flexible manner. Connection with the magnetic field generating device of the applicator’s casing may be ensured
`
`by several points. The several fastening points ensure the connection of the magnetic field generating device to the
`
`casing by flexible material so that the main part of the magnetic field generating device and the main part of the
`
`casing of applicator are spaced apart. The spacing should beat least 0.1 mm so that air can easily flow. Alternatively
`
`the spacing maybeat least 1 mm, most preferably at least 5 mm to enable cooling media flow. The gap between the
`
`magnetic field generating device and the casing can be used either for spontaneous or controlled cooling. The
`
`magnetic field generating device may optionally be connected to the case of the applicator by only one fastening
`
`point. The fastening points eliminate vibrations of wires which could be transferred to casing of the applicator and
`
`therefore reduce noise of the magnetic treatment device.
`
`[0086]
`
`Figure 2 is a cross-section of the magnetic applicator which allows better flow on the lower and
`
`upper sides of the magnetic field generating device and thus moreefficient heat dissipation. The magnetic treatment
`
`device includes a magnetic field generating device 1, the circuit wires 2 and the fastening points 3 for connection of
`
`the magnetic field generating device to the casing of the applicator (not shown). The fastening points 3 are preferably
`
`made offlexible material however the rigid material may be used as well. The fastening points 3 may be located on
`
`the outer circumferential side of the magnetic field generating device. However,alternatively it is possible to put these
`
`fastening points to a lower or upper side of the magnetic field generating device.
`
`[0087]
`
`The fastening points 3 connect the magnetic field generating device to the case of the applicator
`
`in at least one point. The fastening points 3 maintain the magnetic field generating device and the main part of the
`-7-
`
`

`

`caseof the applicator spaced apart so that fluid (which may beair or any liquid) can flow between them. At least one
`
`blower 4 can be placed around the circumference of the magnetic field generating device, or perpendicular to the
`
`magnetic field generating device. The blower can be any knownkind of device for directing the fluid e.g. outer air
`
`directed into the case of the applicator. The blower may be e.g. a fan or a Suction pump. This arrangement of the
`
`blower allows air to bypass the magnetic field generating device from upper and lower (patient’s) sides. In still another
`
`embodiment the outer air can be cooled before directing into the case. The blower can havean inlet placed around
`
`the circumference of the magnetic field generating device for injecting air, to remove heat from the magnetic field
`
`generating device. A connecting tube (not shown) can ensure connection of the applicator 5 with the energy source
`
`and/or control unit of magnetic treatment device. The connecting tube mayalso contain a conduit of the fluid, e.g. a
`
`pressurized air.
`

`
`Alternatively the magnetic field generating device may be attached to the casing of the applicator
`
`via a circular rigid member encircling the magnetic field generating device. The outer circumference of the circular
`
`rigid member maybe attached to the casing of the applicator. The magnetic field generating device may beflexibly
`
`attached to the inner circumference of the circular rigid member by at least one attaching point. Alternatively the
`
`magnetic field generating device may be attached to the circular member byits entire circumference.
`
`[0089]
`
`The arrows6 indicate the air flow through the applicator 5. This arrangement of the blower allows
`
`the air to bypass the magnetic field generating device from upper and lower (patient’s) side. Outlet may be preferably
`
`placed on upper side of the casing. The outlet may include a plurality of holes enabling unimpeded removing of
`
`heated cooling media from the casing of the applicator. By placing the blower around the circumference of the
`
`magnetic field generating device instead of on the top/below the magnetic field generating device, the blower 4 does
`
`not interfere with the magnetic flux peak and thereforeits lifespan and reliability is increased.

`
`Figure 3a is an illustrative embodiment of a casing of the magnetic applicator. The overview
`
`drawing contains casingitself 7, which might contain an outlet 8 preferably placed on upper side of the casing 7. The
`
`applicator may further include a handle 49 on the upper side of the casing. The handle 47 may be used for manual
`
`positioning the applicator. A connecting tube 9 may not only ensure connection of the applicator with the energy
`
`source and/or control unit of magnetic treatment device, but also connection to a source of the fluid; however the
`
`conduit of the fluid 10 may also be connected separately.
`
`[0091]
`
`The connection tube 9 may include a connector for connecting the applicator to the treatment
`
`device. The connector may be connected to the connecting tube 9 either on its first end between the connecting tube
`
`and the casing 7 of the applicator or the second end between the connecting tube and the treatment device. The
`
`applicator including the coil may be preferably connected to the magnetic treatment device by the connector
`
`independently on the positioning arm. The connector may be any kind of electromechanical connector providing
`
`electrical communication of the applicator to the treatment device. Mechanical connection may be provided by
`
`additional
`
`latching mechanism knownin the art. The applicator may be replaced by another applicator. Each
