    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: Provided herein are conjugates, kits, articles of manufacture and methods for detection, diagnosis and treatment by photodynamic therapy of certain undesired biological substrate targets, including, but not limited to bacteria, viruses, and other pathogenic microorganisms, tumors and hyperproliferative tissue. In particular, the conjugates provided include a fluorophore or photosensitizer linked to a targeting moiety and a quenching agent in such a way that activation of the fluorophore or the photosensitizer is quenched unless the targeting moiety is bound to a target, whereupon the quenching agent dissociates or moves away from the photosensitizer, enabling activation of the photosensitizer upon irradiation with light of a suitable wavelength.

    摘要: The present invention is drawn to methods and compounds for photodynamic therapy (PDT) of a target tissue or compositions in a mammalian subject, using a light source that preferably transmits light to a treatment site transcutaneously. The method provides for administering to the subject a therapeutically effective amount of a targeted substance, which is either a targeted photosensitizing agent, or a photosensitizing agent delivery system, or a targeted prodrug. This targeted substance preferably selectively binds to the target tissue. Light at a wavelength or waveband corresponding to that which is absorbed by the targeted substance is then administered. The light intensity is relatively low, but a high total fluence is employed to ensure the activation of the targeted photosensitizing agent or targeted prodrug product. Transcutaneous PDT is useful in the treatment of specifically selected target tissues, such as vascular endothelial tissue, the abnormal vascular walls of tumors, solid tumors of the head and neck, tumors of the gastrointestinal tract, tumors of the liver, tumors of the breast, tumors of the prostate, tumors of the lung, nonsolid tumors, malignant cells of the hematopoietic and lymphoid tissue and other lesions in the vascular system or bone marrow, and tissue or cells related to autoimmune and inflammatory disease.

    摘要: Light is administered during photodynamic therapy (PDT) for an extended period of time at a plurality of sites distributed within the abnormal tissue of a tumor. A clinical study has shown that a substantially greater volume of abnormal tissue in a tumor is destroyed by the extended administration of light therapy from a plurality of probes than would have been expected based upon the teaching of the prior art. In this process, a plurality of light emitting optical fibers or probes are deployed in a spaced-apart array. After a photoreactive agent is absorbed by the abnormal tissue, the light therapy is administered for at least three hours. The greater volume of necrosis in the tumor is achieved due to one or more concomitant effects, including: the inflammation of damaged abnormal tissue and resultant immunological response of the patient's body; the diffusion and circulation of activated photoreactive agent outside the expected fluence zone, which is believed to destroy the abnormal tissue; a retrograde thrombosis or vascular occlusion outside of the expected fluence zone; and, the collapse of the vascular system that provides oxygenated blood to portions of the tumor outside the expected fluence zone. In addition, is possible that molecular oxygen diffusing and circulating into the expected fluence zone is converted to singlet oxygen during the extended light therapy, causing a gradient of hypoxia and anoxia that destroys the abnormal tissue outside the expected fluence zone.

    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: 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 nulluniversalnull base units suitable for operation with different size receiving units.

    摘要: A system and method for excitation of photosensitizers is configured to provide desired illumination on targeted eye tissue. The excitation system includes an optical module that generates illumination and a controller to power the optical module and control the shape, intensity or energy level, and duration of the illumination. The optical module includes a contact portion for interfacing with the eye, a treatment beam portion including a light emitter array to generate shaped light patterns and optics to focus the light patterns onto the eye, and a visualization portion to provide visual feedback of treatment through a visualization interface coupled with a microscope. A typical treatment involves the optical module being placed on a diseased eye of a patient by a clinician to project illumination on a diseased portion of the eye. The clinician typically views the eye through the microscope and the optical module during treatment.
