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 system, an IC chip, a test structure formed on the IC chip, and a corresponding method for modeling one or more target interconnect capacitances is disclosed. The test structure comprises an interconnect configuration comprising a test interconnect and one or more target interconnects. The interconnect configuration has, for each target interconnect, a corresponding target interconnect capacitance between the test interconnect and the target interconnect. The test structure also comprises a test interconnect charging circuit connected to the test interconnect. The test interconnect charging circuit is configured to place a test charge on the test interconnect. The test structure further comprises one or more target interconnect charging circuits. Each target interconnect charging circuit is connected to a corresponding target interconnect. Each target interconnect charging circuit is configured to draw a target interconnect charging current from the corresponding target interconnect in response to the test charge. This places an opposite charge on the corresponding target interconnect that is induced by the corresponding target interconnect capacitance. As a result, a measurement of the corresponding target interconnect capacitance may be computed by making a measurement of the target interconnect charging current with a current meter of the system.

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： A flexible patch provided with a plurality of light sources mounted in spaced-apart array on its undersurface and covered with an optically transparent polymer material. The light sources are energized with an electrical current supplied by a flexible polymer battery, which is preferably rechargeable. Electrical current is conveyed through a lead that extends from the flexible battery to the flexible patch and then through an electrical circuit that includes a plurality of conductive traces formed using a conductive ink applied to the surface of a flexible substrate that supports the light sources. The thickness of the flexible patch at its maximum is less than 1.0 millimeters. The light sources can be separately grouped, and the electrical current supplied to each group individually controlled to achieve a desired light intensity and/or duration exposure to the light therapy over different portions of the undersurface of the flexible patch and different portions of the treatment site. An adhesive applied to the treatment site on the patient's body or on the undersurface of the flexible patch is used to mount the flexible patch to the treatment site. A plurality of slots that extend through the flexible substrate provide passages for air and moisture and enable the flexible substrate to freely and more readily conform to irregular, non-planar shapes of the treatment site. The flexible substrate can also be adhesively secured to a non-planar surface within a patient's body to render the light therapy internally.

摘要： A light delivery system to provide light treatment to a patient includes a catheter assembly having a plurality of light sources that transmit light towards a target site within a patient. In one embodiment, the light delivery system has a plurality of light sources mounted to a flexible transparent base that extends at least partially through a distal tip of the catheter assembly. The light sources can be wire bonded or mounted in a flip chip arrangement onto the base. In one embodiment to produce the distal tip, an array of light energy sources can be held by an array of holders of a fixture device. A vacuum is applied to secure each light energy source in a corresponding holder. While the vacuum is applied, the energy sources are electrically connected by wire bonding. The vacuum can be reduced or stopped thereby permitting removal of the light energy sources from the fixture device.

摘要： A method of manufacture and medical apparatus that provides an apparatus useful in illuminating at least a portion of a lumen of a body. The apparatus includes an elongated flexible member and a polymer encasement portion encasing a plurality of light emitters. The light emitters may be electrically coupled to one another without the use of wire bonds, and in some embodiments may be coupled without intervening electrical paths or traces. A maximum cross-sectional dimension of the polymer encasement portion may be less than twice a dimension of one of the light emitters. In some embodiments the maximum cross-sectional dimension is less than or equal to the sum of the dimension of one of the light emitters and a marginal dimension by which an outer portion of the polymer encasement portion extends beyond the light emitter. Light emitters may be arranged linearly, helically or in partially overlapping back-to-back relation.

摘要： A light transmission system to provide photodynamic treatment to a patient includes a single use integrated control module and catheter assembly having a plurality of light emitting diodes (LEDs) to transmit light toward target cells within a patient. The integrated light catheter and control module are used in combination with a light activated drug. Selected operating parameters may be programmed into the control module, or it may be wirelessly programmable in situ prior to use to allow user flexibility to tailor treatment for a particular patient or condition. Among the features that prevent reuse are that the control module lacks access to recharge the power source, and it may include a deactivation module that destroys circuitry or software when triggered. To prevent patient interference when in use, the control module may also be configured to selectively deactivate.

摘要： The efficacy of light activated therapy treatment is enhanced by stimulating the immune system of the patient substantially above a normal level. Abnormal tissue that is destroyed by the light activated therapy releases factors that stimulate the immune system, leading to systemic reductions in abnormal tissue (i.e., reduction beyond the region treated using light). By further stimulating the immune system using an anti-CTLA-4 antibody, the systemic destruction of abnormal tissue is enhanced.
