  • Publication number: 20100286468
    Abstract: System and methods for Transcranial Magnetic Stimulation (TMS) are described in which regions adjacent (e.g., to the sides and behind the TMS electromagnet) are protected from the high magnetic fields emitted by the TMS electromagnet. Thus, adjacent muscle or neural structures are protected and undesirable side effects are avoid or minimized, allowing stimulation from previously unavailable sites such as the mouth and pharynx.

  • Publication number: 20100286470
    Abstract: Described herein are Transcranial Magnetic Simulation (TMS) systems and methods of using them for emitting focused, or shaped, magnetic fields for TMS. In particular, described herein are arrays of TMS electromagnets comprising at least one primary (e.g., central) TMS electromagnet and a plurality of secondary (e.g., lateral or surrounding) TMS electromagnets. The secondary TMS electromagnets are arranged around the primary TMS electromagnet(s), and are typically configured to be synchronously fired with the primary TMS electromagnets. Secondary TMS electromagnets may be fired at a fraction of the power used to energize the primary TMS electromagnet to shape the resulting magnetic field. The secondary TMS electromagnets may be stimulated at opposite polarity to the primary TMS electromagnet(s). Focusing in this manner may prevent or reduce stimulation of adjacent non-target brain regions.

  • Publication number: 20100256439
    Abstract: When a mechanical frame or gantry is used to move one or more electromagnets about a subject, the pulsed magnetic fields of the magnets need to be triggered, but only when the coil is in an appropriate physical position. Trigger points are established along the movement pathway (e.g., along the support frame) for the electromagnets that trigger the pulsation of the current being supplied to the given electromagnet. Use of the present invention allows firing of a magnetic coil to coordinate with the position of that coil, without need for expensive robotics or computerized motion control.

  • Publication number: 20100256438
    Abstract: Methods, devices and systems for Transcranial Magnetic Stimulation (TMS) are provided for synchronous, asynchronous, or independent triggering the firing multiple of electromagnets from either a single power source or multiple energy sources. These methods are particularly useful for stimulation of deep (e.g., sub-cortical) brain regions, or for stimulation of multiple brain regions, since controlled magnetic pulses reaching the deep target location may combine to form a patterned pulse train that activates the desired volume of target tissue. Furthermore, the methods, devices and systems described herein may be used to control the rate of firing of action potentials in one or more brain regions, such as slow or fast rate rTMS. For example, described herein are multiple electromagnetic stimulation sources, each of which are activated independently to create a cumulative effect at the intersections of the electromagnetic stimulation trajectories, typically by means of a computerized calculation.

  • Publication number: 20100184198
    Abstract: The present invention provides novel methods for removal and disposal of ammonia from spent dialysate in a dialysis system. Ammonium ions present in spent dialysate are converted into gaseous ammonia by raising the pH of the spent dialysate solution in a first reactor. Gaseous ammonia diffuses through a semi-permeable hydrophobic membrane at the outlet of the first reactor and into a second reactor via a gas channel. The second reactor converts gaseous ammonia into an ammonium compound for easy disposal.

  • Publication number: 20090156884
    Abstract: The treatment of specific neurological and psychiatric illnesses using Transcranial Magnetic Stimulation (TMS) requires that specific neuroanatomical structures are targeted using specific pulse parameters. Described herein are methods of positioning and powering TMS electromagnets to selectively stimulate a deep brain target region while minimizing the impact on non-target regions between the TMS electromagnet and the target. Use of these configurations may involve a combination of physical, spatial and/or temporal summation. Specific approaches to achieving temporal summation are detailed.

  • Publication number: 20090099405
    Abstract: Efficient use of multi-coil arrays for magnetic nerve stimulation depends upon coordinating the coil polarity, the pulse phase and the pulse timing. Monophasic magnetic nerve stimulators produce more precise and predictable results in the stimulation of nerves than biphasic and polyphasic machines, but are less electrically efficient, and consequently limited in terms of pulse train speed. The present invention concerns the coordination of pulse polarity, phase, timing, and strength between multiple magnetic stimulation coils. The goal is to optimize the manner in which multiple coils may be used synergistically to control the activity of underlying neural tissue.

  • Patent number: 5363842
    Abstract: The present invention detects how much air is inhaled through the inhaler with what time course (including such derived measurements as how much volume is inspired within the bounds of a given flow range) as well as certain events such as the triggering of the release of aerosol. The system can be set up to compare the resultant time course to either (a) a standard target envelope (e.g., one or more of flow, volume, and time) for that patient programmed into the intelligent inhalation device by a healthcare professional. Based on the comparison, the success or failure of effective inhaler actuation and aerosol inspiration can be signaled to the patient (e.g., visually or through sound) and may be recorded with a time and date stamp for later decoding and evaluation of the invention, the device would also possess the ability to signal the patient to continue post-inspiratory breath holding for use in interpreting the success of medication delivery.

  • Patent number: 5333106
    Abstract: An apparatus for interactive training of a patient in the use of an aerosol inhaler includes a feedback display based upon air flow versus volume data in order to train patients to use a proper sequence of inhalation steps to insure maximum delivery of an aerosol pharmaceutical to target sites in the lungs. Flow and volume data are displayed to provide the patient and physician with a real-time, interactive representation of the inhalation process. Visual feedback to the patient includes a portrayal of the lungs which may be either three dimensional or an outline form in addition to or instead of an X-Y display. An important element of visual feedback is the portrayal of the distribution of representative droplets of aerosol medication in various stages of inhalation and breath holding. Thus, the patient is provided with meaningful feedback representative of the actual distribution of aerosol medication.
