Description

  The present invention is in the field of methods and devices for treating a particular person's illness, specifically treating a brain illness.

  Migraine occurs in approximately 12% of the world population. Thus, there are approximately 30 million people in the United States who suffer from this pain in 2005. Drugs have been created that significantly reduce the suffering of migraine patients, but these drugs are often contraindicated, have very undesirable side effects, and many patients have severe headaches, nausea and nausea associated with migraine Not getting satisfactory relief from other discomfort. Furthermore, migraine headaches are usually treated after they become painful, that is, treatment often has no effect on preventing the development of migraine headaches. Other than some drugs that are effective for some patients, known treatments for migraine that can be applied to prevent the occurrence of migraine pain and other undesirable signs after the patient has noticed a headache Currently does not exist. Non-invasive, drug-free methods to prevent the development of migraine are notable gifts for millions of people worldwide who suffer from these pains and often debilitating experiences.

  In 1985, A.A. T.A. Barker et al. Describe the use of a coil placed over the scalp to create a high-intensity, time-varying magnetic field (Lancet, 1105-1107, published 1985). This magnetic field creates an electric current in the cortex of the human brain, which in turn can cause certain effects on the brain neurons. This type of system has been given the name Transcranial Magnetic Stimulation (TMS). If a magnetic pulse is applied continuously and repeatedly in this manner, the name rTMS is given.

  R.D. from Advances in Therapy, issued May / June 2001. B. Pelka et al.'S paper titled “Impulse Magnetic-Field Therapeutic for Migration and Other Headaches: A Double-Blind, Placebo-Controlled Study on the Source of the Magnetic Field of the Patient An apparatus is described. All devices are only 12 inches from the patient's head. The strength of the 16 Hz magnetic field at the power supply is 5 microtesla. For all patients, the magnetic field in the brain should be less than 1.0 microtesla. This field was applied for 4 weeks, and some benefits were reported from week 1 to week 3. Wearing such a device for weeks is certainly inconvenient compared to a single magnetic pulse or, at best, several such pulses applied during a fraction of a millisecond. A magnetic field strength of only 1 microtesla is considered to be quite inadequate to erase the precursors that precede many migraines.

  In a magazine called Neurology (issued April 11, 2000, pages 1529-1531) Boroojerdi et al. Report that rTMS can reduce the excitability of neurons in the human visual cortex at a rate of 1 pulse / second. However, the article does not point out that TMS or rTMS can be used to prevent the occurrence of migraine or to reduce the intensity or duration of migraine.

  In US Pat. No. 6,402,678, Robert E. et al. Fischell et al. Describe means and methods for the treatment of migraine using a portable device attached to the patient's head. This device is used to create magnetic pulses that act on brain neurons and can remove both the aura that occurs before migraine and the migraine after it begins. However, since the entire device is attached to the patient's head, it is somewhat uncomfortable for patient use. Furthermore, since the trigger control device is also installed on the head to which the device is attached, their operation is somewhat difficult.

  US Patent Application No. In 10 / 929,586, Robert E. Fischell et al. Describe an improved device for applying TMS to brain neurons. However, the application does not describe means for limiting the number of TMS pulses that a patient can place on his / her head, nor does it describe means for confirming that the TMS device operates correctly. In addition, the application has not devised the main features of the present invention, which is a single handheld portable device that includes all circuitry and a magnetic coil that applies TMS pulses to the patient's brain.

  The present invention is a means and method for improving the treatment of many brain diseases, which can be treated by creating a current in the brain with the application of a strong, short duration magnetic pulse or a series of such pulses. Examples of such diseases include all types of headaches, depression, obsessive compulsive disorder, insomnia, bipolar disease, epilepsy or febrile seizures and status epilepticus. It is also expected that extremely strong, short duration magnetic pulses or groups of pulses can be applied as a treatment by stimulation of various nerves such as the occipital or trigeminal nerves near the head and the vagus nerve near the neck. It is also expected that magnetic pulses applied to the neck carotid sinus and / or vagus nerve can be used to stop the onset of atrial fibrillation.

  For the purposes of this disclosure, the use of a single TMS pulse or several TMS pulses for the treatment of migraine is described in detail. However, it should be understood that the system used to treat migraine can also be used to treat other conditions such as those described herein. Of course, multiple magnetic pulses can be used instead of a single pulse. These multiple pulses can be a very large number of single pulses that are separated in seconds to minutes, or rTMS, which is a continuous magnetic pulse. Although patients are described herein as women, it is to be understood that the present invention can be used with men or women and children or adults.

  The present invention is a single device portable magnetic pulser that can be attached to any area where a patient touches his or her head or any area near that head. The pulsar is powered by a battery from a wall receptacle or a car lighter receptacle. After the pulsar is plugged into the power source, the charge switch is pushed by the patient and the capacitor begins to charge a relatively high voltage.

  When this happens, the image display clearly indicates that the capacitor is charging. Ideally, a string of LEDs illuminate from one end to another indicating the progress of the charging cycle. As an alternative, the TMS pulser could use a straight bar where the light gradually illuminates as the capacitor is charged. When the capacitor is fully charged, an image display, such as a green light emitting diode, indicates that the capacitor can be discharged into a low resistance coil at any time, creating a strong, short duration magnetic pulse. It is highly desirable that the image display used be of a color and intensity that does not make any person with migraine so much anxious (eg, a blurred blue light). Examples of such image displays include a series of LED or LCD displays (monochrome or color).

  To increase battery life and / or prevent accidental charging of the capacitor, the charging switch is under the cover and is a sliding or rotating switch, providing a means to prevent a certain period of activation or inadvertent charging You need any other technology. If the charge switch is accidentally pressed, the power supply is cut off to prevent the capacitor from being fully charged.

  Before the patient presses the button to discharge the capacitor to the magnetic coil, the patient attaches the button surface of the pulser to the patient's head or other area of the patient's body to be treated by the magnetic pulse. Powerful, short-duration magnetic pulses, by Faraday's law, create currents in the brain (or anywhere in the body) that are treatments for the patient's illness. For example, if a magnetic pulse is applied to the occipital lobe of the brain during a visible aura before migraine, the aura is substantially extinguished and the patient does not have migraine. Magnetic pulses applied elsewhere on the human body can be used to generate current pulses where the current pulses can be treated.

  An important factor in the design of a TMS pulser is the ability to limit the number of pulses that a patient can apply to his brain without the permission of the physician who prescribed the device for use by the patient. If the number of pulses that the device can deliver is unlimited, the patient may allow unauthorized persons to use the device without proper prescription from the physician. By limiting the number of pulses that can be applied without a refill prescription from the patient's attending physician and by charging a modest amount for each pulse used, the patient allows others to use their pulser I don't mind. However, as a matter of course, devices capable of applying pulses without limitation are also considered to be included in the concept of the present invention.

  A potential safety aspect of the present invention is that the TMS pulser can limit the number of pulses per unit time that a patient can receive. For example, the device can be designed to allow no more than 10 pulses (for example) per hour.

  To meet the need for available pulse refills, the pulsar can include a standard RJ-11 telephone jack. The RJ-11 telephone jack can be used to allow the device manufacturer to add a pulse over the telephone connection if the patient is authorized by a refill prescription from his attending physician. The telephone connection can also be used to communicate the pulse usage, date and time stamped for patient monitoring, from the TMS pulser to the patient's attending physician or to the central diagnostic center. A telephone connection can also provide device diagnostics if the pulsar does not work properly. Alternative means of providing additional pulses and reading data into and reading data from the pulser use a USB key or other device that connects to a standard type computer input connection such as an Ethernet connection. It was. Once inserted into the pulsar, the USB key can be used to increase the number of allowed pulses. Of course, any supplementation of the pulse must be approved by the patient's attending physician's effective and up-to-date supplemental prescription.

  A USB key is typically a standard USB memory with encoded data, which instructs the TMS pulser to accept a specified number of pulses allowed. In any case, the TMS pulser is designed so that once the USB key is removed and reinserted, the USB key can only use additional pulses and not add a second additional pulse.

  It is envisioned that other telecommunication interfaces such as Wi-Fi over the Internet or wired Ethernet can be used instead of telephone connections. In addition, other standard flash memory devices such as compact flash cards, memory sticks or SD cards can be used in place of the USB memory or USB key.

  Since the number of pulses available to the patient (using one mode of the invention) is limited, it is important for the patient to know the exact number of residual pulses. To that end, an LCD, LED (or other) display (or audio) can be provided that indicates the number of residual pulses. If the number of available pulses falls to the number used by the patient in just a few days, the patient can ask the attending physician for a refill prescription, or the refill prescription can serve various patients Recorded in the agency that provides the. The patient can then receive a refill from the patient service organization through a telephone connection or using a USB key. Of course, once the patient has a previously used USB key, refilling is due to the use of a USB slot on a personal computer connected to the TMS pulser manufacturer (or authorized service organization) via the Internet. The TMS pulsar manufacturer (or authorized service organization) confirms the refill prescription and source of payment for the pulse, and properly encoded data to allow further pulses. Send to key. The patient then removes the latest USB key and inserts it into the TMS pulser.

  It should also be understood that the USB key can be mailed or purchased at the patient's local drugstore. Of course, the history of the date and time stamped for the number of pulses used is available to the attending physician or manufacturer from data stored in the pulser's digital memory using a telephone connection or USB port. The USB port operates by connecting to a PC using a cable or by sending data to a USB key that is later inserted into a USB slot of a computer connected to the Internet.

  Furthermore, it will be appreciated that the magnetic pulser system includes self-testing means to confirm that the amplitude and time of the magnetic pulse are within specified limits. This is done by a separate wire coil placed near the magnetic coil of the device, which measures the amplitude and time course of the magnetic pulse. If the amplitude or time course of the magnetic pulse is outside its specified limits, the magnetic pulser system can produce an error signal that can be detected by the patient and determined by the patient service center via a telephone or internet connection. The warning is using an image display or audio warning. In addition, the patient is provided with a separate device that can be used to examine the amplitude and time course of the magnetic pulse. This is an external device, on which the patient mounts the TMS pulser and then activates the pulser. The external device then measures the magnetic pulse. It is also expected that a closed-loop control system can be used, in which case the level measured in the previous pulse is used to change the charging parameters of the following pulse in order to maintain the magnetic pulse within predefined limits. Can be used. Such calibration is performed manually (there is a calibration button) or automatically each time the TMS pulser pulsates.

  Another important aspect of the present invention is that each pulsar has a unique serial number that is recorded for a particular patient. When the TMS pulser receives instructions to send stored data on pulse usage or append pulses, the data sent to and from the TMS pulser must be encrypted, thereby permitting It is basically impossible for a non-human to add pulses to the pulsar or access the patient's pulse usage to treat a disease in the patient's brain (or other). In addition, the safety link allows the patient to be recognized only with their serial number, so that the actual name of the patient is not known to the manufacturer's service center operator. Thus, patient confidentiality is maintained.

  Another important aspect of the present invention is the shape of the magnetic coil. In US Pat. No. 5,116,304, J. Pat. A. Cadwell describes a magnetic coil having a calvarial shape. Although this design functions to provide TMS pulses, the present invention describes an improved coil design that is a track-shaped, true elliptical or pseudo-elliptical coil. Any of these shaped coils, usually long in one direction compared to the length perpendicular to the long axis of the coil, is described here as an elliptical shape. Elliptic coils are curved around the short axis and usually conform to the curvature of the human head. The curved elliptical shape for the TMS magnetic coil allows both the left and right occipital lobes to be stimulated simultaneously. Therefore, in order to eliminate the visible signs of migraine, the patient only needs to collect the long axis of the coil over the centerline of the occipital lobe of his or her head, after which the patient has either side of the occipital lobe in his eye Regardless of whether it is the source of visible signs, remove those signs.

  Although TMS systems that have been used for brain research for many years have the ability to produce magnetic pulses that can be used effectively for therapeutic purposes, all previous TMS systems were very large and over 50 pounds. Therefore, they are not actually portable in normal patients. Furthermore, these systems have never been operated by a patient, but rather by medical personnel performing brain research experiments. One preferred embodiment of the present invention is a truly portable device that can be carried in at least a female patient's large handbag. The present invention thus defines that the portable magnetic pulsar system is a TMS device that is operated by the patient and is less than 10 pounds. The optimal pulsar weighs less than 4 pounds. However, it should be appreciated that the present invention is a non-portable magnetic that weighs over 10 pounds and is almost always in the patient's home (or another location where the patient spends most of his time) as needed. It can also be a pulsar system. However, in all cases, the TMS magnetic pulser is operated by the patient.

  Accordingly, it is an object of the present invention to have a magnetic pulser that is portable and operated by a patient to treat brain disease or other human organ disease, the magnetic pulser being a neuronal cell to be treated Or designed to provide one or more strong, short duration magnetic pulses applied to other body parts.

  Another object of the present invention is to limit the total number of pulses available before refilling and to limit the number of pulses allowed in a given time.

  Yet another object of the present invention is to provide additional magnetic pulses provided using a telephone (or internet) connection or from a USB key, based on supplementary prescriptions from an authorized pulse provider and from the patient's attending physician. To have availability.

  Yet another object of the present invention is to have a refill data message in an encrypted format so that pulse refill cannot be performed without proper permission.

  Yet another object of the present invention is to have a curved elliptical coil for a pulsar capable of producing magnetic pulses across one or both sides of the occipital lobe of the brain.

  Yet another object of the present invention is to have an image display on the TMS pulsar that can indicate the number of residual pulses, the status of the charge cycle and the capacitor being fully charged.

  Yet another object of the present invention is to have means to prevent inadvertent activation of a charge switch that starts a capacitor charge cycle.

  Yet another object of the present invention is to have an image display designed to minimize discomfort in people suffering from migraine.

  These and other objects and advantages of the present invention will become apparent to those of ordinary skill in the art upon reading the detailed description of the invention, including the associated drawings presented herein.

  1, 2 and 3 are a side view, an end view and a top view of the magnetic pulser 10, respectively. 1, 2, and 3 show the electronic device portion 20 that is coupled to the magnetic coil portion 40 by the coupling structure 30. 1, 2 and 3 show the information and control display panel 21 including the charging switch 22, the pulse button 23, the ready light 24, the charging display bar 27 and the remaining pulse number display 28. FIG. 3 shows that the number of residual pulses is 39. When the plug 51 of the power cord 50 (of FIG. 3) is plugged into the power receptacle 25, the remaining pulse number display is illuminated. Thereby, the patient knows that the magnetic pulser 10 is supplied with power. Even when the magnetic pulser 10 has a built-in battery, or for other reasons, an on-off switch (not shown) can be used or can be used. When the magnetic pulser is powered, the patient presses the charge switch 22 to begin charging the capacitor 31 (shown in FIGS. 4 and 6). The degree to which the capacitor 31 is charged is indicated by a charge display bar 27. Instead of a charging bar, an array of individual lights can also be used to indicate that the capacitor 31 has been charged. When capacitor 31 is fully charged, all bars 27 become bright and ready light. When that happens, the patient attaches the curved surface 41 of the magnetic coil portion 40 to his head and then presses the pulse button 23 which causes the capacitor 31 to discharge to the magnetic coil 42 (shown in FIGS. 5 and 6). . This creates a TMS magnetic pulse that can depolarize the neurons in the brain, thus eliminating the visible aura and preventing migraine. Whenever a pulse is created, the remaining pulse number display 28 is decremented by one. To prevent accidental charging of the capacitor 31, the charging switch 22 is under a cover and is a sliding or rotary switch, any other technique that provides a means to prevent charging for a period of time or inadvertent charging. Need.

  FIG. 3 shows one shape of the power cord 50, that is, a type that is plugged into a normal household receptacle. The power cord 50 has a plug 51 that is electrically connected to the transformer rectifier 52 using a wire 53. The transformer rectifier 52 has two or three protrusions that plug into a 115 volt AC household receptacle in the United States. It is also conceivable that different types of power cords can be plugged into the car's conventional cigarette lighter (or other power source). In any case, the voltage at the normal plug 51 is 12 volts DC. It is also anticipated that the power cord will be joined to a battery having a primary or rechargeable battery, either of which can be used to power the magnetic pulser 10. Furthermore, it should be understood that the magnetic pulser 10 may have a built-in battery that is a rechargeable battery or a used replaceable battery.

  1, 2 and 3 also show a receptacle access wall 18 in which a power supply receptacle 25 and a USB key receptacle 26 can be installed. The USB key receptacle 26 is used with the USB key 60 of FIG. 3, as will be described below with reference to FIG.

  FIG. 4 is a partial cross-sectional view of the magnetic pulser 10 and shows a cross-section of the display panel 21 including the charge switch 22, the pulse button 23, and the ready light 24. FIG. 4 also shows the receptacle access wall 18, the coupling structure 30 and the magnetic coil portion 40. One or more capacitors 31 are shown in the coupling portion 30. An electronics module 29 is shown in the electronics section 20. The components in the electronic device module 29 are described below with reference to FIG.

  FIG. 5 is a cross-sectional view of the magnetic pulser 10 and shows the coupling structure 30 when coupled to the magnetic coil portion 40. A wall 31 made of plastic is usually formed around the entire magnetic pulser 10. The curved surface 41 of the magnetic coil portion 40 is designed with substantially the same curvature as the human head. A perfect match to the specific head curvature is not required for the therapeutic effect to be achieved. The curvature of surface 41 having a radius that is greater than 3 inches and less than 6 inches is acceptable for magnetic pulsar system 10. A radius of curvature of approximately 4.5 inches will satisfy most patients. The exact curvature of any patient is thought to closely match the curvature of the patient's particular head. For example, a manufacturer could create three different curvatures: a small curvature, a medium curvature, or a head with a curvature that exceeds the average.

  FIG. 5 also shows a typical arrangement of the wires forming the magnetic coil 42. FIG. 5 shows an electrical wire with a solid metal (which can have an insulating coating) and a conventional circular cross section, but the improved design has many strands, each independent of the other strands of that wire. Is a litz wire. Another suitable cross-section for the wire is a rectangle with a very thin dimension in one direction (0.001 inch to 0.1 inch) and an orthogonal dimension between 0.2 inch and 0.8 inch. The optimal design is a litz wire with a collection of strands that are square in cross section. Copper is a suitable metal from which the magnetic coil 42 is made, but pure aluminum wire has a very light advantage. The optimum wire for the magnetic coil 42 is probably an aluminum litz wire with a square or rectangular cross section.

  FIG. 5 also shows a single magnetic stack 43 formed in the shape of the magnetic coil 42. Although only one stack is shown, a large number of magnetic stacks can be used to increase the magnetic field strength in the head direction while reducing the magnetic field strength in the coupling structure 30 direction. . The ferromagnetic material from which the stack 43 is made includes silicon iron or any other magnetic material having a relatively high permeability and saturation flux density.

  FIG. 6 is a block diagram of the magnetic pulser system 10. A power supply receptacle 25 (from an external power supply) activates a DC-DC converter 71 (or an AC-DC converter not shown) to provide adequate power to all the electronic equipment shown in FIG. To do. The output of the converter 71 goes to a control circuit 70 that controls charging and discharging of the capacitor 31. A high voltage transmission line (typically between 300 and 800 volts) is used to charge the capacitor 31. Although a single high voltage capacitor is used, it is often more advantageous to combine at least two capacitors in series or in parallel.

  The magnetic pulsar system 10 is controlled by a central processing unit (CPU 79) according to instructions stored in the memory 75. When power is applied to the power supply receptacle, the CPU 79 is activated from the memory 75 and the power-on light 86 is lit. Instead of power-on-light, the number 29 of remaining pulses can be illuminated to indicate that the power is on. The CPU 79 allows an appropriate number to be shown on the residual pulse display 29. Memory 75 includes at least a portion of non-volatile memory so that the remaining number of pulses and patient data are retained even when system 10 is unplugged or powered off.

  Once the CPU 79 is activated, the system 10 can be used at any time. If there is a residual pulse, the patient activates the charge switch 22 which causes the CPU 79 to activate the control circuit 70 to begin charging the capacitor 31. When the capacitor 31 is charged, the control circuit 70 monitors the voltage and communicates this information to the CPU 79. When the capacitor 31 reaches full charge, the CPU 79 activates the charge indicator bar 27, which is usually a continuously illuminated bar, or alternatively, first one LED is lit, then two, then three, etc. A linear array of LEDs is activated until all arrays are lit. When the capacitor 31 is fully charged, the CPU 79 activates the ready light 24, which is normally green. The patient then places the surface 41 of FIG. 5 on the appropriate part of the head (or other body part) and then presses the pulse button 23. The pulse button 23 informs the CPU 79 to instruct the control circuit 70 to discharge the capacitor through the magnetic coil 42. A preferred embodiment of the pulse button 23 integrates the ready light 24 and the button 23.

  When the magnetic pulse is started, the ready light 24 is turned off, the irradiation bar on the charging display bar 27 is turned off, and the residual pulse display 29 shows one less pulse.

  A further feature of the electrical circuit system of the magnetic pulsar system 10 is that the audio circuit system 74 can provide an audio signal (which is a verbal signal) through the speaker 73 when the ready light is lit. The speaker 73 informs the patient that the magnetic pulser system 10 can provide magnetic pulses at any time. When the pulse is complete, the audio circuitry 74 can also communicate through the speaker 73 that the pulse has been sent. Further audio signals can provide other messages such as errors present, the device not functioning, ie the voltage is too low, or there are few residual pulses. In any country where the device is sold, the audio signal is the language of the country or a limited range of words or dialects of the country.

  The USB key 60 when inserted into the USB port 26 can be used to increase the number of residual pulses by a specific number specified in the doctor's refill prescription and paid by the patient. For example, the replenishment performed by the USB key is 25, 50 or 100 additional pulses. The CPU 79 and memory 75 can also hold an encrypted PIN that does not allow any input for further pulses not provided by the manufacturer's service center. In addition, the memory 75 can store the date and time for each pulse sent by the TMS pulsar system 10. The time history of the pulses used by the patient can be stored in the memory 75 and can be read out through the data communication circuit system 73 via the USB port 26, the Ethernet (registered trademark) jack 82 or the RJ-11 telephone jack 84.

  In order to monitor the shape of the magnetic pulses sent by the magnetic pulse system 10, a small magnetic field detection coil 76 is placed in close proximity to the magnetic coil 42. If the amplitude and / or duration of the magnetic pulse is outside the pre-specified range, the coil 76 is sent to the pulse measurement circuit 77, which sends an error signal light (on the magnetic pulser system 10) to the CPU 79. Tell them to illuminate (not shown). The letter “E” or “ER” also appears on the pulse counter, indicating that an incorrect pulse was generated. The patient is also warned using the audio circuitry 74 and the speaker 73 that the pulse is outside certain limits. Using a data communication connection via USB port 26 or Ethernet jack 82 or RJ-11 telephone jack 84, a technician at the patient service center can determine whether the magnetic pulse is within its specifications and each magnetic pulse. Determine if it is within the correct time calendar. Thus, each device in the patient's hand is examined to make sure it is functioning properly. To avoid tampering, it is envisioned that a magnetic pulse system 10 is provided that is completely inoperable due to the opening in the case. This is through deletion of the activation instruction in the memory 71 or through other means.

  FIG. 7 shows a normal magnetic pulse that can be produced when the capacitor 31 discharges to the magnetic coil 42. Ideally, a peak magnetic field of about 1.0 ± 0.5 Tesla is created in the middle of the lower surface of the magnetic coil 42. The time to maximum pulse intensity varies from a minimum of 10 microseconds to a maximum of 10,000 microseconds, but the time to reach the maximum magnetic field strength of the pulse is ideally 175 ± 100 microseconds. Most importantly, the time rate of change of the magnetic pulse is fast enough to create a therapeutic current in the brain or other human cellular tissue. The maximum magnetic field strength in the brain is at least 0.05 Tesla. If the maximum value of the magnetic field in the brain is less than 0.05 Tesla, the magnetic pulser system 10 will not work for many patients. To create a magnetic field in the brain that exceeds 5 Tesla, a magnetic pulsar system 10 of excessive weight and size is required. Thus, the acceptance range for the maximum value of the magnetic field in the patient's brain is between 0.05 Tesla and 5.0 Tesla. A suitable range for the maximum strength of the magnetic field in some parts of the patient's brain is between 0.2 Tesla and 1.0 Tesla.

  It should be understood that an effective magnetic pulsar system 10 is made utilizing several, if not all, features described herein. For example, a magnetic pulsar system can be created and operated effectively without the features of pulse measurement. Another example is an audio signal to a patient that can also be removed, and a more effective magnetic pulser system can work for the treatment of migraine and other diseases. These are just two examples of some that can be removed, and the magnetic pulser system 10 is still valuable to most patients. It should also be understood that the use of the word “capacitor” means one or more capacitors.

  Various other modifications, adaptations and design alternatives are, of course, possible in light of the teaching presented herein. Accordingly, it is to be understood that the invention can be practiced otherwise than as specifically described herein, while still falling within the scope and meaning of the appended claims.
