    摘要： Front-end and side-on intravascular catheters are described that comprise an abrasive head contained substantially within a housing. Aspiration means and flushing means are connected to the region of grinding to remove dislodged debris. A preferred embodiment has the abrasive surface of a rotatable head comprised of diamond powder. Another preferred embodiment has an ultrasonic transducer affixed to the head to permit transluminal imaging of the site of occlusion.

    摘要： Front-end and side-on intravascular catheters are described that comprise an abrasive head contained substantially within a housing. Aspiration means and flushing means are connected to the region of grinding to remove dislodged debris. A preferred embodiment has the abrasive surface of a rotatable head comprised of diamond powder, fused silica, tungsten carbide, aluminum oxide, or boron nitride. Another preferred embodiment has an ultrasonic transducer affixed to the head to permit transluminal imaging of the site of occlusion.

    摘要： A dental condensing instrument having an elastomeric tip of sufficient size to surround the margins of a prepared cavity, which will yieldably urge the flow of soft restorative materials inside prepared cavities to improve their adaptation to cavity walls and margins without the introduction of deleterious air voids therein. When hand pressure is applied, the tip will not only seal said margins, but also apply a steady, isostatic condensing force upon said materials.

    摘要： An improved catheter system having an ultrasonic imaging transducer coupled to a drive cable disposed within a lumen of a flexible tubular catheter body. An improvement including a reconfiguration of the ferrites in the hub assembly, such that the need for the gap between the ferrites is removed. A strain relief member is provided to increase the strength of the electrical transmission lines to enable them to withstand the tensile forces caused by either flushing and/or pull-back operations. A device which allows the electrical transmission lines to extend their length when placed in tension may also be employed to provide strain relief to the electrical transmission lines. Another improvement includes a counter-wound coil structure, which may either expand or contract as the drive cable is being rotated to strengthen the drive cable. The distal tip of the catheter body may be redesigned to provide a lumen which allows for the release of flushing fluids through a distal port in the guidewire lumen.

    摘要翻译： 一种改进的导管系统，其具有耦合到设置在柔性管状导管主体的内腔内的驱动电缆的超声成像换能器。 包括轮毂组件中的铁氧体的重新配置的改进，使得铁氧体之间的间隙的需要被去除。 提供应变消除构件以增加电力传输线的强度，使得它们能够承受由冲洗和/或拉回操作引起的张力。 允许电气传输线在放置在张力时延长其长度的装置也可用于向电气传输线提供应变消除。 另一个改进包括一个反绕线圈结构，其可以随着驱动电缆的旋转而膨胀或收缩，以加强驱动电缆。 可以重新设计导管主体的远端，以提供允许通过导丝管腔中的远端释放冲洗流体的内腔。
