    摘要: A phased array transducer for an ultrasonic imaging system includes a flexible support element which supports an array of piezoelectric transducer elements. Shape transducers such as strain gauges or capacitive transducers are coupled to the support element to generate a signal indicative of the instantaneously prevailing curvature of the array. A user-controlled actuator is coupled to the support element to flex the support element between at least first and second configurations, wherein the support element has separate curvatures along the axis of the transducer in each of the first and second configurations. In some applications the transducer elements are positioned for separate scan formats in the first and second configurations. The support element can be provided with first and second alternating regions which differ in flexibility, in order to concentrate flexing of the support element in the second regions. In some applications the support element may have a cross-sectional dimension of less than about ten millimeters to facilitate insertion of the transducer into a tortuous vessel of a living subject.

    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: 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 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.
