    摘要： The preferred embodiments include a method for manufacturing an end portion surrounding a catheter-mounted phased-array ultrasound transducer. The material used for the end portion can be altered to give the end portion focusing, defocusing, or non-focusing characteristics. In one preferred embodiment, a thermoplastic material is injection molded or insert molded around a phased-array ultrasound transducer carried at a distal end of a catheter. In another preferred embodiment, a thermoset material is used to form the end portion using a casting or transfer molding technique. In yet another preferred embodiment, the phased-array ultrasound transducer is placed into a pre-formed end portion. The pre-formed end portion can be adhesively-attached to the phased-array transducer and catheter. If the pre-formed end portion is made from a thermoplastic material, the end portion can be thermally melted to attach the end portion to the phased-array transducer and catheter.

    摘要： A controller for an ultrasonic transducer assembly includes a housing having a longitudinal axis that extends generally parallel to the proximal end of a conduit, such as a catheter. A steering actuator is mounted to the housing for rotation about the longitudinal axis, and a steering hub is mounted for rotation in the housing and coupled to the steering actuator such that rotation of the steering ring with respect to the housing causes rotation of the steering hub. A steering line is secured adjacent the steering hub and extends to the distal end of the conduit such that rotation of the steering hub alters the effective length of the steering line to steer the distal end. The steering line is wrapped at least partially around a stator to avoid threading the steering line through multiple holes and slots prior to termination to the steering hub. The steering line is preferably formed of a liquid crystal polymer, and the housing of the steering mechanism preferably contains an extension portion to ensure that the portion of the housing that the user grips to manipulate the steering mechanism is sufficiently far away from the cable to ensure that the cable will remain sterile and thus reusable. In an additional preferred embodiment, the controller is contoured to a human hand to provide a comfortable, efficient, and enjoyable one-handed operation.

    摘要： According to the present invention, an ultrasonic transducer probe is provided having an array of ultrasonic transducers rotatably mounted about an axis within the ultrasonic transducer probe, a lens mounted to the array, and a housing encasing the array and the lens. The lens is symmetric about the axis of rotation of the array. In addition, the housing has a continuous upper surface that is formed, in a region adjacent to the symmetric lens, to mate with the symmetric lens.

    摘要： A method for the early diagnosis of Bordetella diseases based on the detection of Bordetella adenylate cyclase and the ability of this enzyme to catalyze the formation of cyclic adenosine monophosphate (cAMP). A sample secretion is taken from a suspected victim of a Bordetella disease (the most common of which in humans is whooping cough) and incubated under conditions to promote the formation of cAMP, which may then be measured as evidence of the presence of the disease. A sample of nasopharyngeal secretions is maintained in a nutrient medium pending assay. An adenylate cyclase assay is made by incubating the sample with adenosine triphosphate (ATP) and the calcium binding protein calmodulin to generate cAMP. The cAMP is measured by any of several known available methods. To facilitate diagnosis, a kit is provided containing the materials necessary for collection of secretion specimens, for storage of specimens pending assay, and transport of specimens to the assay laboratory, and for performing the assay and determining the result.

    摘要： A method and agents are disclosed for raising the tolerance of animal tissue to antibiotic compounds that induce oxidant stress. The method comprises administering one or more nontoxic redox compounds to the locus of administration of the antibiotic in an amount sufficient to diminish the production of the potentially toxic oxidants. The redox compounds may be administered by various parenteral techniques. The agents comprise redox compounds and include redox dyes such as those of the thiazine group. Of this group methylene blue is preferred. A method for treating cancer in animals is also disclosed.
