摘要： An apparatus and method for operating a catheter guiding assembly, with one lumen providing access for an ultrasound imaging catheter and a second lumen providing a working port for a tool. Optionally, the ultrasound imaging catheter in the catheter guiding assembly is exposed to blood, and the ultrasound imaging catheter port has a gasket. Alternatively, the catheter guiding assembly is sealed to prevent blood contact by the ultrasound imaging catheter, and the ultrasound imaging catheter may be re-used several times. In either case, the working tool is in the field of view of the ultrasound imaging catheter and normally exposed to blood. Because the working tool is exposed to blood, the working port has a gasket to keep blood from leaking out. Optionally, the working port is used for fluid delivery for injecting contrast agent, chemicals or drugs, which can be activated by sonification from the ultrasound imaging catheter.

摘要： A needle guide having a semi-compliant shell design and locating means for attachment to an ultrasound transducer. The needle guide improves over the prior art in its reduced complexity, its low-profile formed fit to the transducer, a positive guide locking feature when the needle holding pin is in the closed position, and its ease of attachment over a sterile cover. The improved design is conducive to low-cost manufacturing methods which employ materials that can be autoclaved, gas-sterilized, or liquid disinfected.

摘要： An ultrasound transducer assembly is disclosed having a housing, a transducer array mounted in the housing and an electronics assembly mounted in the housing, the electronics assembly including one or more sub-assemblies having heat generating components disposed thereon. The electronics sub-assemblies further include thermal conducting features which conduct heat generated by the heat generating components out of the electronics assembly where it can be further removed by other thermal management techniques. These other thermal management techniques may include techniques utilized to cool the transducer array.

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.
摘要翻译： 用于超声换能器组件的控制器包括壳体，该壳体具有大致平行于诸如导管的导管的近端延伸的纵向轴线。 转向致动器安装到壳体上以围绕纵向轴线旋转，并且转向轮毂安装成用于在壳体中旋转并联接到转向致动器，使得转向环相对于壳体的旋转引起转向轮毂的旋转 。 转向线固定在转向轮毂附近并且延伸到导管的远端，使得转向轮毂的旋转改变转向线的有效长度以转向远端。 转向线至少部分地围绕定子包裹，以避免在终止到转向轮毂之前将转向线穿过多个孔和槽。 转向线优选地由液晶聚合物形成，并且转向机构的壳体优选地包含延伸部分，以确保用户抓住操纵转向机构的壳体部分足够远离电缆以确保 电缆将保持无菌并因此可重复使用。 在另外的优选实施例中，控制器被轮廓化为人的手，以提供舒适，有效和愉快的单手操作。
