  • Patent number: 7863454
    Abstract: 3-substituted-6-aryl pyridines of Formula I are provided: wherein R1, R2, R3, R8, R9, A and Ar are defined herein. Such compounds are ligands of C5a receptors. Preferred compounds of Formula I bind to C5a receptors with high affinity and exhibit neutral antagonist or inverse agonist activity at C5a receptors. The present invention also relates to pharmaceutical compositions comprising such compounds, and to the use of such compounds in treating a variety of inflammatory, cardiovascular, and immune system disorders. In addition, the present invention provides labeled 3-substituted-6-aryl pyridines, which are useful as probes for the localization of C5a receptors.

  • Patent number: 7730894
    Abstract: Light generating devices for illuminating portions of vascular tissue, to render photodynamic therapy. In one embodiment, a light source array preferably including a plurality of light emitting diodes, a focusing lens, and a light diffusing element are included in a distal end of a catheter. A balloon is optionally provided to interrupt blood flow that can block the transmission of light, and to center the apparatus in a blood vessel. Optical fibers optionally direct light from the light source to the diffusing element. The light source array can have a radial or linear configuration and can produce more than one wavelength of light for activating different photoreactive agents. Linear light source elements are particularly useful to treat elongate portions of tissue in a vessel. One embodiment intended for use with a conventional balloon catheter integrates light sources into a guidewire.

  • Publication number: 20090036773
    Abstract: A combined imaging/HIFU probe includes an imaging scan head, a HIFU transducer, and an outlet port that delivers a flow of fluid across the HIFU transducer. At least a portion of the body cavity is filled with fluid in which the probe is immersed. The fluid provides a coupling for transmission of ultrasound energy between the probe and the patient. A flow of fluid may also be used to flush obstructions from an area of tissue near the HIFU transducer. Further described herein is a cuff to help retain fluid in the body cavity, a regulator to regulate fluid flow with respect to the body cavity according to a desired fluid pressure, and a cover for the HIFU transducer that has at least one perforation defined therethrough to allow fluid to flow through the cover. Further disclosed herein are methods of deploying a combined imaging/HIFU probe in a body cavity.

  • Publication number: 20080033519
    Abstract: Light sources are incorporated into a guidewire for enabling the ability to render light therapy be added to catheters that do not have that capability. In one exemplary embodiment, a solid guidewire includes a conductive core, and light sources are added to compartments formed in a distal end of the guidewire. In another exemplary embodiment, a light source array is included in a distal end of a hollow guidewire. A plurality of openings are formed into the walls of the hollow guidewire surrounding the array, enabling light to pass through the openings. Conductors extend from the array though the hollow center of the guidewire, to a proximal end of the hollow guidewire. The hollow guidewire can be coated with a conductive material, so that the coating on the guidewire serves as a conductor.

  • Publication number: 20070260295
    Abstract: 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.

  • Publication number: 20070002582
    Abstract: 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.
