`ABSTRACT
`(57)
`The invention relates to a device and a method for repetitive
`nervestimulation in order to break down fat tissue by means
`of inductive magnetic fields, which device and method permit
`easy patient-related adjustability and control in order to
`reduce fat tissue in defined body regions, such as the abdo
`men, buttocks, or thighs, in a targeted manner and without
`body contact. The invention uses the effect of the stimulation
`of muscle contractions by contactless induction of electric
`fields by means of pulsed magnetic fields in the tissue. By
`influencing the electric currents, pulsating magnetic fields are
`also able to stimulate ion transport and measurably increase
`metabolism. An increase in the circulation of the blood and
`increased oxygen Supply are demonstrably

`DEVICE FOR REPETITIVE NERVE

`
`CROSS REFERENCE TO RELATED
`APPLICATION
`0001. This application is related to and claims priority
`from the German PCT Patent Application No. PCT/IB2013/
`001896 filed on Jul. 2, 2013, which claims priority to German
`Patent Application No. 10 2012 013 534.3 filed on Jul. 5,
`2012.
`0002 The present invention makes use of the effect of
`stimulating muscle contractions by contactless induction of
`electrical fields by means of pulse-shaped magnetic fields in
`the tissue. Pulsating magnetic fields are also capable of excit
`ing ion transport by influencing the electric currents and
`measurably increasing metabolism. There is a demonstrable
`increase in blood circulation and an increased Supply of oxy
`gen. These effects are currently being medically evaluated
`from the point of view of the reactivation of muscles after
`illness or accident and have already led to corresponding
`inventions. Thus, from DE 10 2007 044 445 A1, a training
`device with magnetic stimulation is known wherein in con
`junction with means for mechanically guiding an intended
`movement of a joint in a paralysed body part, this body part is
`stimulated to move. From US 2005/203332A1, a device for
`the treatment of osteoporosis and other musculo-skeletal dis
`eases is known in which the patient, lying on a couch, is
`surrounded at the respective part of the body by a cylindrical
`coil which generates an electromagnetic field. From U.S. Pat.
`No. 6,213,933 B1 a device and a method for dissolving blood
`clots in human body parts can be inferred, in which the patient
`lies on an elongated platform over which a transversely
`extending, longitudinally movable holder with a water
`cooled magnetic field coil of the butterfly type is arranged for
`stimulation. In order to position the magnetic field coil, the
`holder is simply pushed over the part of the body that is to be
`treated. The frequency and duration of stimulation is con
`trolled by an interactive programme on a PC. Another elec
`tromagnetic system known from US 2003/0158585 A1 uses
`ergonomic stimulating coils in the form of flexible flat or
`cylindrical coils, adapted to the contour of the particular body
`part, for therapeutic treatment, for stimulating nerves,
`muscles and other tissues of the human body.
`0003) Beyond this—and not previously utilised muscle
`excitation by magnetic field stimulation leads to a breakdown
`offatty tissue in the area around the muscles, as the Applicant
`has demonstrated by numerous experiments, particularly on
`obese and muscular test Subjects. In slender test Subjects,
`there is a development of muscle with no significant weight
`loss.
`0004 Admittedly, there were already devices and methods
`for treating obesity or excess weight by means of pulsating
`magnetic fields, but these either require, in addition to the
`field-generating coil, another permanent magnet in contact
`with the surface of the body (DE 100 62050A1) or they act
`indirectly through a magnetic field that activates the thyroid
`(DE 10 2009 043 728 A1) and also have to be applied to the
`body by means of a neck band.
`0005 Thus, using the experience and findings described
`above, the object of the invention is to provide a device and a
`method for repetitive nerve stimulation for breaking down
`fatty tissue by means of inductive magnetic fields, which
`
`permit easy patient-centred adjustment and control, in order
`to reduce fatty tissue in defined regions of the body, such as
`the abdomen, buttocks or thighs, in targeted manner and
`without any body contact.
`0006. This object is achieved by the device claimed in
`claim 1 and the method claimed in claim 14. Advantageous
`embodiments of the invention are the subject of the sub
`claims.
`0007 Advantages of the invention consist particularly in
`the contactless induction of excitation, the associated low
`levels of the pain stimulation that occurs with alternative
`electrical excitation, the large area of excitation and the abil
`ity to position the stimulation-producing coil to Suit the indi
`vidual body shape of the patient.
`0008 Essential components of the device are a large-area
`magnetic field coil through which current passes, hereinafter
`referred to as the stimulation coil, which is attached to a stand.
`Different coil shapes are provided for the treatment of the
`abdomen, buttocks and thighs.
`0009. The stimulation coil produces magnetic fields with
`peaks at a magnetic flow density of 0.01 T to 0.1T at about 5
`cm in front of the surface of the coil. The magnetic field can
`be varied over time and consists of diphase or monophase
`pulses with a pulse duration T of 100 us to 300 us. The repeat
`frequency of the pulses (stimulation frequency f.) is 10Hz to
`30 Hz. Maximum electric field intensities of 0.1 V/cm to 1
`V/cm are achieved by induction at the stimulation site in the
`tissue. The magnetic field of the coil is approximately locally
`constant in magnitude throughout the Volume of tissue to be
`treated. Parameters of a typical coil are shown in Table 1.

`0010. The stimulation coil is actuated by means of a pulse
`generator (stimulator), which is installed separately from the
`stand. A stimulator of the kind currently used as a prototype in
`medical research (IMETUM, Central Institute for Medical
`Technology, Technical University of Munich, Concluding
`Report: “Functional peripheral magnetic stimulation of
`motor functions in patients with central paresis, particularly
`hemiplegic paralysis”, 2011) with a pulse length of 160 us
`(diphase) may be used. The capacity of a capacitor is matched
`to the inductivity of the stimulation coil in order to tune the
`resonating frequency of an LC resonator consisting of the
`stimulation coil and the capacitor, to the frequency corre
`sponding to the pulse duration. The electric fields required
`give rise to high currents through the coil in the range from
`500 A to 6000 A.

`
`0011. The large area of the coil enables it to have an open,
`non-cast structure. As a result, the considerable Joule’s heat
`produced in the coil can be removed by means of an air fan.
`Airflow is provided for effective cooling. Contamination and
`dust turbulence are prevented by filter mats.
`0012. The treatment times range from 1 minto 45 min. The
`long times can be achieved without overheating of the coil
`thanks to the effective cooling and the coil design.
`0013 The coil itself may, on account of its size, be pro
`duced as a self-supporting structure of Solid metal (e.g. cop
`per or aluminium). This assists the conduction of heat away
`from the coil conductor to its surface. The cross-section of the
`conductor is 1 cm to about 2 cm. This large cross-section of
`the coil conductor, by comparison with that of coils used in
`site-selective magnetic field stimulation (focussing), reduces
`the ohmic resistance, thus reducing the Joule's heat.
`0014. Alternatively, the coil may also be produced from
`high-frequency wires, by conventional technology, to avoid
`skin and proximity effects. However, an estimation of the skin
`depth shows that this is not necessary with a pulse duration of
`about 200 us.
`0015. In a solid construction, it may also be conceivable to
`use hollow conductors which are cooled by a coolant liquid.
`0016. The stimulation coil is encapsulated in a plastic
`housing. The housing ensures protection from contact Voltage
`and at the same time directs the coolant air.
`0017. The fan produces a current of coolant air which
`reaches the coil through air inlet openings and air guiding
`elements fitted with filters which are provided in the plastic
`housing of the stimulation coil, and this coolant airis Supplied
`to the air outlet openings of the fanthrough an air guide made
`of plastics which is arranged around the electric connecting
`leads to the coil. The fan may consequently be arranged at the
`back of the stand and outside the magnetic field of the stimu
`lation coil, thus preventing any adverse effects on the electric
`fan motor.
`0018. As a result of the high currents, high mechanical
`forces occur between the conductor sections of the stimula
`tion coil and the connecting leads. These are absorbed by
`ceramic retaining elements which maintain a spacing.
`0019. The electric connecting wires to the stimulation coil
`in the stand are of solid construction with no movable cables.
`This permits an optimum release of heat into the air, absorp
`tion of the magnetic forces and high operational reliability.
`0020. The stimulation coil is mounted on a holder which is
`formed by the solid current supply lines themselves. This
`holder positions the coil at an adequate distance from the
`stand;
`0021 the unwanted eddy currents induced in the stand by
`the coil are minimised in this way.
`0022. A stimulation coil can easily be changed after open
`ing a torsionally and axially mounted closure sleeve with a
`bayonet closure and loosening two screws for the connecting
`leads. This is significant, as different optimum coil shapes
`with different housings are used for different areas of the
`body (abdomen, thighs and buttocks).
`0023 The positioning of the stimulation coil relative to the
`patient can be varied by means of a variable-height pedestal.
`Thus the connecting leads to the stimulation coil can be made
`rigid in design and changes in the inductivity and input resis
`tance caused by changes of position can be avoided.
`0024. Alternatively, positioning of the stimulation coil on
`the stand could be carried out by the use of clamping closures
`in vertical rails.
`
`0025. The stimulation of muscle contraction can be opti
`mised by means of a feedback link. For this purpose, the
`contractions triggered by a stimulation coil are observed
`using a camera integrated into the stand and corresponding
`signals are transmitted to a computer (e.g. a laptop). This
`controls the electrical pulses located at the output of the pulse
`generator in terms of pulse form, duration, amplitude and
`treatment time, by means of a corresponding programme,
`depending on the signals received.
`0026. An embodiment of the invention which demon
`strates further advantages and special features is shown in
`FIGS. 1 to 8 and described in more detail hereinafter.

`prising control software for computer-aided optimisation of
`the stimulation, a fan (10) for cooling the magnetic field coil

`
`netic field coil (3), a shielded cable channel (12) for the
`necessary electrical connecting wires between the stand (1)
`and the pulse generator (11) or the operating console (8) and
`a spotlight (13) for correctly illuminating the area of the body
`captured by the camera (6). It should be mentioned that the
`pulse generator (11) may advantageously be arranged
`directly on the stand (1) in order to minimise conduction
`losses. In this case, therefore, the cable channel (12) shown is
`dispensed with. Also shown is the power unit (14) belonging
`to the Voltage Supply of the device, which is configured and
`installed separately on account of the high heat levels pro
`duced, with output voltages of between 500 and 1000 V and
`the associated connecting cables (15).
`0051. The stand (12) approximately adapted to the mag
`netic field line pattern in the upper region consists essentially
`of a hollow frame (16) made of plastics with internally
`located ceramic retaining elements (17) for the precise posi
`tioning of the spaced-apart connecting leads (18, 19) with a
`lead cross-section of 1.5 cm (FIG. 2a, b). These connecting
`leads (18, 19) ensure the passage of current between the pulse
`generator (11) and the stimulation coil (3). They may also be
`embodied as hollow conductors. Roughly level with a
`patient’s waist, the stand (1) comprises a fixedly installed
`tubular air conveying channel (20) extending horizontally and
`transversely through the stand (1), with the connecting leads
`(18, 19) inside it. The connecting leads (18, 19) are passed
`from the air conveying channel (20) through sealed bores into
`the stand (1).
`0052 FIG. 1 further shows the camera (6) also provided in
`the stand (1), which can be positioned by means of an adjust
`ment ring (7) so that the part of the body being treated is
`reliably captured. A spotlight (13) at the upper end of the
`stand (1) serves to illuminate the part of the body being
`treated.
`0053. The variable-height pedestal (4) may comprise a
`mechanical lifting device which is operated and locked by
`means of a foot lever (5). A vertical upright is a possibility.
`Scissor-type Supports arranged vertically above one another
`with a threaded spindle interposed horizontally may also be
`opened or closed for the height adjustment, the threaded
`spindle being rotated by hand or by an electric motor. A
`hydraulic lifting cylinder with a foot pump may be used as
`another means of adjusting the height of the pedestal (4).
`0054 FIG.2a shows the stand/stimulation coil connecting
`arrangement in detail, comprising the stand (1), the air con
`veying channel (20) and the fan (10) for cooling the connect
`ing leads (18, 19) and the stimulation coil (3). A closure sleeve
`(21) with bayonet closure, mounted to be axially movable and
`rotatable, covers the start of the air conveying channel (20)
`and the end of the stimulation coil (3) to prevent touching of
`the lead couplings.
`0.055 FIG.2b is a sectional view of the stand? stimulation
`coil connecting arrangement. The air conveying channel (20)
`in the hollow frame (16) of the stand (1) comprises, at an end
`remote from the patient, the fan (10) with air outlet openings
`(34) which aspirates air through the air inlet openings (22) in
`the plastic housing (2) of the stimulation coil (3), through
`filter mats (23), past air guidance elements (not shown), the
`windings (24) of the stimulation coil (3) and the connecting
`leads (18, 19), in order to cool it. The lead coupling (25) for
`the outgoing and return conductors of the connecting leads
`(18, 19) is also shown.
`0056 FIG. 3a shows the lead coupling (25) for outgoing
`and return conductors in section. Each end of a conductor in
`
`the stimulation coil (3) comprises a thickened, cylindrical end
`portion (26) with an external thread (27). A horizontal trap
`ezoidal slot (28) is milled into this end portion (26). A trap
`ezoidal tab (29) protruding from a thickened, cylindrical end
`portion (30) of one of the connecting leads (18) or (19)
`engages in said slot (28). An internally threaded screw bush
`ing (31) which surrounds one of the thickened end portions
`(30) of the connecting leads (18) or (19) is screwed onto the
`external thread (27) of one end portion (26) in each case and
`connects the connecting leads (18, 19) to the stimulation coil
`(3). By means of these two lead couplings which can be
`pushed on and Screwed tight, the stimulation coil (3) is Sup
`ported by the connecting leads (18, 19). This special screw
`connection simultaneously serves to conduct electricity. As
`the conical flanks of the trapezoidal slot (28) lie with their
`surface against the flanks of the trapezoidal tab (29), there is
`also a slight contact resistance.
`0057 FIG. 3b is a perspective view of the lead coupling
`used for outgoing and return conductors in the screwed State.

`FIG. 4a shows, for example, the stimulation coil (3)
`for treating the abdomen, in perspective view from the front
`(treatment side). The drawing shows a clampable protective
`cover (32) which has been removed, and a substantially trum
`pet-shaped plastic housing (2). On the inside of this trumpet
`shaped plastic housing (2) are a plurality of ceramic retaining
`elements (17) for accommodating the windings (24) of the
`stimulation coil (3). The ends of the windings (24) of the
`stimulation coil (3) are guided parallel to the thickened end
`portions (26). The windings (24) for treatment of the abdo
`men themselves run Substantially in an oval and cover an area
`of about 20 cmx30 cm. The air inlet openings (22) can also be
`See.
`0059 FIG. 4b shows the stimulation coil (3) for treatment
`of the abdomen, in perspective view from behind (the stand
`side). Clearly visible are the thickened end portions (26) with
`the external threads (27), the respective trapezoidal slots (28),
`ceramic retaining elements (17) and a groove (33) in the
`plastic housing (2) of the stimulation coil (3) for guiding the
`axial and rotary movement of the closure sleeve (21).
`0060 FIGS. 5a, 5b, 5c and 5d show various representa
`tions of a stimulation coil (3) for treating the buttocks region;
`(a) the housing viewed from in front, (b) the housing viewed
`from the side, (c) the housing viewed from above and (d) the
`configuration of the coil inside the housing, seen from the
`viewpoint of the person being treated. This stimulation coil
`(3) has the same internal construction as the stimulation coil
`(3) for treating the abdomen and essentially only differs in the
`external shape of the housing. The treatment side of the hous
`ing has a rounded-off square shape measuring about 15
`cmx15 cm. The protective cover (32) has a slightly concave
`curvature. The stimulation coil (3) itself comprises suitably
`shaped windings (24) extending in a square configuration.
`The back of the plastic housing (2) has a Swan-necked shape
`so that the stimulation coil (3) can act slightly below the
`patient's waist.

`configuration of the coil inside the housing, seen from the
`viewpoint of the person being treated. This stimulation coil
`(3) has the same basic construction as the stimulation coil (3)
`for treating the buttocks, the difference being that the treat
`ment side has a rounded-off rectangular shape measuring

`
`about 10 cmx20 cm, the protective cover having a slightly
`concave curvature extending in the vertical direction.
`0062 FIG. 7 shows, by way of example, a basic circuit
`diagram of a conventional pulse generator (11) as used here,
`which only generates its own stimulation pulse producing
`unit in conjunction with the stimulation coil (L) (cf. lead
`couplings LK). Voltages of between 500 V and 1000 V com
`ing from the separate power unit (14) are selected in stages of
`50 V by means of electronic switches (not shown here) which
`are controlled either manually by means of the operating
`console (8) or by the computer (9), and applied to the reser
`voir capacitor (C1) at the input of the pulse generator (11), for
`storage. The selected charge Voltage of this reservoir capaci
`tor (C1) essentially determines the stimulation power and
`hence the amplitude level of the stimulation pulse that is to be
`generated. The actual energy store, the pulse capacitor (C2),
`is charged up and recharged by means of the thyristor circuits
`A and B. In principle the pulse capacitor (C2) forms with the
`stimulation coil (L) an oscillating circuit which is damped by
`the ohmic resistors of the connecting leads and couplings,
`generally shown in the drawing as ohmic resistor (R). Repeti
`tive discharges of the pulse capacitor (C2) and hence the
`stimulation frequency f. are controlled by means of two
`thyristors (T1, T2) connected in antiparallel manner and
`capable of carrying heavy current, which connect the pulse
`capacitor (C2) to the stimulation coil (L). As a result of the
`antiparallel connection of the thyristors (T1, T2), sinusoidal
`diphase Voltage and current pulses may be generated (FIG. 8
`and associated description). Their pulse duration T can be
`adjusted by the connection or disconnection of capacitors
`(not shown here) connected in parallel to the pulse capacitor
`(C2), as this enables the overall capacity in the oscillating
`circuit and hence the oscillating circuit frequency f (f -1/
`(2CV/LC) to be varied. Both the thyristor actuation for select
`ing the stimulation frequency f. and also the number of
`parallel-connected capacitors for determining the pulse dura
`tion T can be manually pre-set on the operating console (11)
`or are controlled by the computer (9).
`0063 FIG. 8 shows, by way of example, an idealised cur
`rent flow in a stimulation coil (3) with diphase actuation by
`the pulse generator (11). A stimulation coil inductivity of
`15x10 H, a charging voltage U of 1000 V and a diphase
`stimulation pulse with a pulse duration T of 300 ms were
`assumed. After the thyristor (T1) is switched through (FIG. 7)
`a positive half-wave of a sinusoidal current flow with a maxi
`mum amplitude of about 3000A is obtained. At time T/2, i.e.
`after half the pulse duration Thas ended, the current 1(t) in the
`oscillation circuit changes its polarity and the thyristor (T2)
`(FIG. 7) is switched through and takes over the current con
`duction until a complete sinusoidal oscillation has been
`reached. Meanwhile, the thyristor (T1) is blocked. The nega
`tive half-wave of the sinusoidal current flow thus produced
`also has a maximum amplitude of about 3000 A. As both
`thyristors (T1, T2) are blocked after a pulse duration.T. further
`oscillation is prevented, so that only a diphase pulse is pro
`duced. Only after a stimulation pulse repeat time T has been
`reached which corresponds to the reciprocal of the stimula
`tion frequency f. are the thyristors (T1, T2) Switched
`through again in the manner described and the pulse-shaped
`current flow in the stimulation coil is obtained once more, as
`also shown in FIG.8. The pulse-shaped currents shown then
`ensure, in the stimulation coil (3), a corresponding formation
`and breakdown of pulse-shaped magnetic alternating fields
`
`within a treatment time interval that can be set at the operating
`console (8) or is controlled by the computer (9).
`0064. If the thyristor T2 is never switched through, a
`monophase current pulse is produced which consists only of
`the positive half-wave of the sinusoidal current flow I(t)
`shown in FIG. 8.
