摘要： The present invention provides a prophylactic light activated treatment method for subjects at risk of a plaque-mediated thrombotic event, such as acute coronary syndromes. In one embodiment, the subject receives a dose of photosensitizer sufficient to result in a concentration of photosensitizer in the neovascularization associated with atherosclerotic disease to permit effective photodynamic therapy. Light of a wavelength that excites the photosensitizer, but that does not to any significant extent penetrate to an adventitial layer of the blood vessel, is applied to the region of the blood vessel. The therapeutic light dose, which may be applied in sequential stages, is sufficient to cause closure of neovasculature leakage and lead to plaque stabilization and reduced adverse clinical outcomes. The present invention further provides light transmission devices and systems useful in carrying out the methods of the present invention.

摘要： The efficacy of light activated therapy treatment is enhanced by stimulating the immune system of the patient substantially above the pre-therapy 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 area treated using light), so long as the light therapy conditions favor apoptosis over necrosis. The volume of abnormal tissue destroyed is maximized to the extent possible, reducing tumor load, which reduces an amount of immunosuppressive factors in the body, enabling stimulation of the immune system to be successful.

摘要： The efficacy of light activated therapy treatment is enhanced by use of additional therapeutic agents. Abnormal tissue is destroyed by light activated therapy, and the associated administration of one or more additional therapeutic agents can synergistically enhance the therapy. For example, the concepts disclosed herein encompass the use of the following agents in combination with light activated drug therapy: (1) agents that selectively inhibit heat shock protein 90 (Hsp90); (2) agents that inhibit the Hedgehog pathway (which is believed to play a central role in allowing the proliferation and survival of certain cancer-causing cells, and which is implicated in many of the most deadly cancers); and, (3) agents for reducing the anti-apoptotic effects of Bcl-2 or Bcl-xL. These agents can be used with light activated drug therapy individually, or in various combinations and permutations.

摘要： A photosensitizer suitable for use in administering photodynamic therapy (PDT), conjugated with antibodies that are targeted to antigens on abnormal tissue and polyethylene glycol (PEG) or other polymer that extends the residence time of the conjugate within a patient's body. The resulting pegylated targeted conjugate is administered to a patient, and after the antibodies have had sufficient time to bind with the antigens, light from an external or internal source having a waveband corresponding to an absorption waveband of the photosensitizer is administered. Use of an external light source that emits relatively long wavelength light enables the light to pass through any intervening dermal layer and normal tissue between the external light source and the treatment site. Since the photosensitizer in the conjugate is bound to the abnormal tissue, the light therapy has minimal effect on the intervening normal tissue. Furthermore, the efficacy of the PDT is enhanced due to the increased concentration of the photosensitizer of the conjugate linked to the abnormal tissue.

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.
