    摘要: Some embodiments provide a system for external manipulation of magnetic nanoparticles in vasculature using a remotely placed magnetic field-generating stator. In one embodiment, the systems and methods relate to the control of magnetic nanoparticles in a fluid medium using permanent magnet-based or electromagnetic field-generating stator sources. Such a system can be useful for increasing the diffusion of therapeutic agents in a fluid medium, such as a human circulatory system, which can result in substantial clearance of fluid obstructions, such as vascular occlusions, in a circulatory system resulting in increased blood flow. Magnetic nanoparticles are provided having a non-specialized chemical coating facilitating association with a chemical composition by a user before infusion. Systems are provided for delivering a consistent infusion mass of magnetic nanoparticles to a patient.

    摘要: A magnetic material having a magnetic heating efficiency of at least 4.5x10-8 J.m/A.g in a cyclic magnetic field where the product of the amplitude and frequency of the applied field is less than or equal to 5x108 A/m.s, and the frequency of the applied filed is at least 20 kHz. The ideal magnetic material is characterized by a perfectly rectangular hysteresis loop, i.e. loop squareness of 1, with coercivity of 25 kA/m or less and high saturation magnetization. Preferably the magnetic material has a predominately cubic magnetic crystalline anisotropy. Preferably the magnetic material is a substituted magnetite (Fe3O4) or gamma-ferric oxide (gammaFe2O3) crystalline lattice in which some of the iron atoms in that crystalline lattice have been substituted for one or more alternate metals atoms. Desirably, the metal atom is a member of the group: cobalt, zinc, nickel, manganese, magnesium, copper, chromium, gallium, cadmium.

    摘要: A container (10) for irradiation comprises a flexible, flat collapsible wall (12, 13) defining a sealed chamber (36), the plastic material of the wall (12, 13) is substantially transparent to irradiation, typically ultraviolet radiation. Access ports (22, 24, 26) are provided for communicating through the wall (12, 13) to the chamber (36). A flap (32) is provided, integral with the wall (12, 13) and spaced from the chamber (36), and carries identifying indicia (38) including a typical bar code indicia (40), so that the wall (12, 13) may be at least substantially free of opaque indicia. Also, structure may be provided for detecting and indicating exposure of the container to irradiation, such as ultraviolet sensitive tape (50) adhering to the flap (32). Alignment holes (46) may be provided, typically in the flap (32), to facilitate orientation of the container (10) with apparatus for irradiation (51) and apparatus for bar code reading (72), making use of alignment pins (70) carried by such apparatus (51).

    摘要: A magnetotherapeutic plug enables the treatment of rectal and vaginal inflammations especially haemorrhoids, by direct action on said tissue, and comprises magnetic elements (N S).
    The plug is adapted to the anatomic shape of rectal and vaginal cavities, so that it provides reliable contact with the tissue, without sharp edges that could damage the tissue during use, so that it is applied easily and simply and remains in place without falling out during treatment.
    The magnetic flux density does not exceed 80 mT, preferably being from 20 mTto 40 mT.

    摘要: An implantable medical device includes an implantable coil case that contains a communications coil. A magnet receptacle is located within the coil case at the radial center and has a magnet opening in one of the lateral surface or the medial surface of the coil case. A magnet fitting groove is recessed into one of the lateral or medial surface of the coil case and extends from the magnet opening to the outer circumference of the coil case. A u-shaped implant magnet clip has parallel clip legs that are connected at a closed end of the u-shape, and an implant magnet is attached to one of the clip legs. The coil case and the magnet clip are configured to cooperate for a portion of the coil case to fit between the clip legs and the implant magnet to slide through the magnet fitting groove and fit through the magnet opening into the magnet receptacle.

    摘要: A method is described for estimating skin thickness over an implanted magnet. A plane is defined that is perpendicular to the skin of a patient over an implanted magnet and characterized by x- and y-axis coordinates. The magnetic field strength of the implanted magnet is measured using an array of magnetic sensors on the skin of the patient. From the measured magnetic field strength, at least one x-axis coordinate in the plane is determined for at least one y-axis zero position on the array where a y-axis component of the measured magnetic field strength is zero. From that, a y-axis coordinate of the at least one y-axis zero is calculated as a function of the at least one x-axis coordinate, such that the y-axis coordinate represents thickness of the skin over the implanted magnet.
