`
`FIELD OF THE INVENTION
`
`[0007]
`
`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 proposes further to combine the magnetic
`
`field with radiofrequency,light, mechanical or pressure source in order to provide an apparatus for improved treatment.
`
`BACKGROUND OF THE INVENTION
`
`[0008]
`
`Aesthetic medicine includesall 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 procedures providing satisfactory results with minimal risks.
`
`[0009]
`
`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 treatment or light treatment, such
`-1-
`
`
`
`as intense pulsed light 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 waves is based especially on heat production in the
`
`biological structure. However the currently used treatment methods are used separately.
`
`[0010]
`
`A mechanical treatment using mechanical waves and/or pressure were used for treatment ofcellulite or adipose
`
`cells. However, mechanical treatment includes several drawbacks such asrisk of a panniculitis and/or non-homogenous result.
`
`[0011]
`
`A thermal treatment is applied to the patient for enhancing a visual appearance of 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.
`
`[0012]
`
`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.
`
`[0013]
`
`Current magnetic methods arelimited in key parameters which do not allow satisfactory enhancementof visual
`
`appearance. As a result, new methods are needed to enhance the visual appearanceofthe patient.
`
`[0014]
`
`Existing devices have low efficiency and they waste energy, whichlimits 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 mustbe protected
`
`during reverse polarity of resonance. This requires using protective circuits which consume significant 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
`
`lowest
`
`layer of the skin and contains hair follicle roots,
`
`lymphatic vessels, collagen tissue, nerves and also fat forming a
`
`subcutaneous white adipose tissue (SWAT). The adiposecells create lobules which are bounded by connective tissue, fibrous
`
`septa (retinaculum cutis).
`
`[0015]
`
`Another part of adipose tissue, 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.
`
`[0016]
`
`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 may be painful so that a topical anesthetic is recommended.
`
`[0017]
`needed.
`
`The development of new aesthetic treatment methods providing improved results in shorter time periods is
`
`SUMMARYOF THE INVENTION
`
`[0018]
`
`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. In a first 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 may beflexibly attached in a casing of device. The casing may comprise a blower or blowers which ensure cooling of the
`
`magnetic field generating device.
`
`[0019]
`
`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 arrangedto blow air on both sides of magnetic field generating device. Optionally, the magnetic field generating
`
`device may bea flat type magnetic field generating device.
`
`[0020]
`
`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.
`
`[0021]
`
`The method oftreating 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.
`
`[0022]
`
`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
`
`appearance of 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 neogenesisof the collagen and elastin fibers.
`
`[0023]
`
`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.
`
`[0024]
`
`On the other hand, a combination with a magnetic treatment method may enhancethe visual appearance ofthe
`
`muscle and/or other soft tissue such as skin or adipose tissue, including increase of apoptotic index.
`
`[0025]
`
`The methods enable combined treatment using different treatment methods such as magnetic and/or auxiliary
`
`treatment methods. The combination ofdifferent treatment methods provide a complex treatment method for focused treatment of
`
`a treated body region.
`
`[0026]
`
`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 may heat adipose cells, dermis,
`
`hypodermisor other target biological structure. Ultrasound waves mayalso induce a cavitation.
`
`[0027]
`
`The present methods and devices mayinclude a handheld applicator, for manual and precise treatment of 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 homogenoustreatmentof large areas oftissue. In some embodiments, the
`
`handheld applicator may be connected to the scanning unit by an attaching mechanism which in 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.
`
`[0028]
`
`Present method and devices may also 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 speed or direction of movementof the optical spot, the wavelength or
`
`wavelengths of the optical waves, the frequency, or optical flux density. Such a change may provide more homogenoustreatment
`
`or mayprotect the patient from discomfort or harm.
`
`[0029]
`
`The present method provides combined treatment using magnetic treatment and thermal
`
`treatment. A
`
`combination of heating/cooling may causean 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
`
`-3-
`
`
`
`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.
`
`[0030]
`
`Although methods ofthe present invention may be described herein as a sequenceof steps in a 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, some or all of the steps of a method of the present invention may be
`
`repeated.

`DETAILED DESCRIPTION
`
`[0077]
`
`It is to be understoodthat the figures and descriptions of the present invention have been simplified toillustrate
`
`elements that are relevant for a clear understanding of the present invention, while eliminating, for the purpose ofclarity, many
`
`other elements found in related systems and methods. Those of ordinary skill in the art may recognize that other elements and/or
`
`steps are desirable and/or required in implementing the present invention. However, because such elements and steps are well
`
`knownin the art, and because theydo notfacilitate a better understanding of the present invention, a discussion of such elements
`
`and steps is not provided herein. The disclosure herein is directed to all such variations and modifications to such elements and
`methods knownto those skilled in the art.
`
`[0078]
`
`The magnetic treatment device may include at least one magnetic field generating device. Alternatively the
`
`magnetic treatment device mayinclude a plurality of the magnetic field generating devices. The at least one applicator may include
`
`at least one magnetic field generating device. Alternatively at least one applicator may include the plurality of the magnetic field
`
`generating devices.
`
`[0079]
`
`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.

`Eq. 1
`
`[0080]
`
`where:
`
`Peppy is power loss per unit mass (W-kg"); Bp is the peak of magnetic field (1); f is frequency
`
`(Hz); d is the thickness of the sheet or diameter of the wire (m); k is constant equal to 1 for a thin sheet and 2 for a thin wire; ¢ is
`
`the resistivity of material (Q-m); D is the density of material (kg-m*).
`
`[0081]
`
`The individual insulation of each wire reduces eddy currents. The individually insulated wires may be wound
`
`either one by one or in a bundle of individually 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 improvementin the efficiency of energy transfer
`in the LC resonantcircuit and also reducesor eliminates unwanted thermal effects.
`
`[0082]
`
`The magnetic field generating device may have a planar magnetic field generating device shape where the
`
`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 handthe 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:

`
`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 as to eliminate air bubbles between the individual insulated wires. The space between wires can befilled with
`
`suitable material which causesunification, 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 movementsofthe individual insulated wires are suppressed. Therefore noise is reduced.

`
`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 may include 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 PCincluding display unit, an input unit and/or a graphical user interface.
`
`[0088]
`
`The mechanical fixture may berigid 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 byflexible 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 may be at 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.

`
`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.
`
`[0090]
`
`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 case of the applicator spaced
`
`apart so that fluid (which may be air 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 have
`
`an inlet placed around the circumference of the magnetic field generating devicefor 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 pressurizedair.

`
`Alternatively the magnetic field generating device may be attachedto 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 maybe flexibly attached to the inner circumference of the
`
`-7-
`
`
`
`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.
`
`
`
`[0092] The arrows6indicate 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 mayinclude 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 doesnotinterfere with t
