    摘要: A flux generator base unit electromagnetically coupled with a receiving unit to transfer energy into the receiving unit. The base unit includes one or more permanent magnets that produce a magnetic flux, which passes through a receiver coil in the receiving unit. The receiver coil is either disposed in a separate housing that is electrically connected with a portable device, or integrated into the housing of the portable device. Either the permanent magnets or a flux shunt is moved in the base unit to produce the varying magnetic flux that is coupled to the receiver coil. As a result of the varying magnetic field experienced by the receiver coil, an electric current is induced in the receiver coil, which is conditioned (e.g., rectified, filtered, and regulated) by a conditioning circuit to charge a battery or energize electronics contained in the portable device. Various embodiments of both the base unit and receiving unit are disclosed, including “universal” base units suitable for operation with different size receiving units.

    摘要: A magnet used for concentrating a medical substance carried by a magnetic fluid at an internal treatment site. The magnet is inserted through an opening in a patient's body and advanced to the internal treatment site. Although an electromagnet is used in one alternative embodiment, the magnet is preferably a super neodymium or other rare earth permanent magnet having a high field strength. A probe that includes the magnet is coated with a biologically inert material, such as a TEFLON.TM. polymer. Alternatively, a plurality of such magnets can be employed. In the preferred embodiment, a magnetic fluid that includes particles coated with a photoreactive agent is injected into the patient's body, preferably, immediately adjacent to or inside the treatment site. The particles in the magnetic fluid are attracted to the magnet at the treatment site, and the concentration of the photoreactive agent absorbed into the tissue around the magnet at the internal treatment site is enhanced. The photoreactive agent is used to provide a photodynamic therapy (PDT) to the treatment site that destroys cells that have absorbed the photoreactive agent when the internal treatment site is illuminated by light of an appropriate waveband. A PDT probe having a light source that emits light of the required waveband is inserted into the patient's body and advanced to the treatment site to effect the PDT. The magnet (or magnets) can also be disposed inside the PDT probe, which then carries the magnet(s) to the internal treatment site.

    摘要: Several different embodiments of a flexible polymer battery are disclosed in connection with providing a medical therapy. For example, the electrical current from the polymer battery may be used to energize light sources for administering light therapy. In one embodiment, the polymer battery is formed as a substantially elongate structure having one end attached to an internal receiver coil, and the other end attached to a medical device such as a light probe that is adapted to be implanted within a patient's body. The polymer battery thus provides a conductive link between the internal receiver coil, which is electromagnetically coupled to an external transmitter coil for recharging the battery, and the light probe which is energized with current supplied by the flexible polymer battery. In another embodiment, the polymer battery is used to support a substrate on which a plurality of light sources are mounted in spaced-apart array. Yet other forms of the invention include polymer batteries within capsules or bead to energize light sources contained therein. The beads include receiver coils for recharging the polymer battery. Further, because of their small size, the beads or capsules are readily moved or held at a treatment site with an external magnet while therapy is rendered. Since a polymer battery includes very little metal, it is less likely to cause artifacts when the patient's body is imaged.

    摘要: The alignment and positioning of an external device relative to an internal device is indicated on a display and/or by an acoustical signal. In the disclosed application, the external device transcutaneously transmits electromagnetic energy to an internal receiver to provide electrical power for an implanted medical device. To ensure optimal coupling between the external transmitter and the internal receiver, two permanent magnets are disposed at spaced-apart positions on the internal receiver. The magnetic field strength of the permanent magnets is sensed by a pair of correspondingly spaced-apart Hall effect sensor on the external transmitter. As the external transmitter is moved about over the internal receiver, the signals produced by the Hall effect sensors drive a display of light emitting diodes (LEDs) that indicates when the maximum magnetic field strength is achieved, i.e., when the Hall effect sensors on the external transmitter are each positioned directly opposite the corresponding permanent magnets on the internal receiver.

    摘要: An external power head is energized by a motor causing movement of an element that produces a varying magnetic field, thereby inducing power in an implanted receiver coil within a patient's body. The external power head includes either one or more moving permanent magnets, or one or more moving elements that vary the magnetic flux coupled to the implanted receiver coil. As a result of the varying magnetic field experienced by the implanted receiver coil, an electric current flows from the implanted receiver coil to energize an implanted medical device.

    摘要: Several embodiments of relatively compact transmitter coils and receiver coils having an improved transcutaneous power transfer efficiency. The transmitter coils are preferably applied to the outer surface of a cutaneous layer on a patient's body and held in place using adhesive tape or other appropriate supporting material. Implanted within the patient's body is a receiver coil. To improve the power transfer efficiency of one embodiment, a transmitter coil and receiver coil include cores having pole faces with a substantially larger area than the cross section of the core at other locations. In addition, the core of the receiver coil is substantially shorter than that of the transmitter coil so that the lines of flux produced by the transmitter coil tend to pass through the pole faces of the receiver coil in greater density than they would if the pole faces of the transmitter and receiver cores were spaced identically. Relatively compact configurations for the transmitter core include an angled portion adjacent each of the pole faces so that the main portion of the transmitter core is disposed generally parallel and closely spaced to the surface of the cutaneous layer against which the transmitter core is placed. Further, two separate transmitter windings are provided on the transmitter core with an intermediate section joining the portions of the core on which these windings are disposed. This configuration provides enhanced power transfer capability compared to using a single winding around the intermediate section of the core.
