    • In a first embodiment, an ultrasound energy delivery assembly includes a waveguide and a catheter having a capture member. The capture member extends radially inward from an interior surface of the catheter into a lumen of the catheter and is configured to retain the enlarged distal tip so that the enlarged distal tip is temporarily prevented from moving proximally. In a second embodiment, an ultrasound energy delivery assembly includes a waveguide and a sheath covering at least a portion of the waveguide. In a third embodiment, an ultrasound energy delivery assembly includes a waveguide and a dual lumen catheter having a capture member. In a fourth embodiment, an ultrasound energy delivery assembly includes a waveguide and a catheter having a proximal waveguide lumen and a proximal guide wire lumen that merges with the proximal waveguide lumen at their respective distal ends to form a distal lumen. In a fifth embodiment, an ultrasound energy delivery assembly includes a waveguide and a catheter having a helical spring tip disposed over a distal section of the waveguide. In a sixth embodiment, an ultrasound energy delivery assembly includes a waveguide and a catheter extruded from a material such as expanded polytetrafluoroethylene. The catheter includes a braided layer having a multi-wire braided section and a single wire braided section formed from a braid wire from the multi-wire braided section.
    • 在第一实施例中,超声能量输送组件包括波导和具有捕获构件的导管。 捕获构件从导管的内表面径向向内延伸到导管的内腔中,并且构造成保持放大的远端尖端,使得放大的远端尖端被临时阻止向近侧移动。 在第二实施例中,超声能量输送组件包括波导和覆盖波导的至少一部分的护套。 在第三实施例中,超声能量输送组件包括波导和具有捕获构件的双腔导管。 在第四实施例中,超声能量输送组件包括波导和导管,其具有近端波导管腔和近端导丝管腔,其在其各自的远端处与近侧波导管腔合并以形成远端内腔。 在第五实施例中,超声波能量输送组件包括波导和导管,其具有设置在波导的远端部分上方的螺旋弹簧顶端。 在第六实施例中,超声能量输送组件包括波导和从诸如膨胀聚四氟乙烯的材料挤出的导管。 导管包括具有多丝编织部分的编织层和由多丝编织部分的编织线形成的单丝编织部分。

    • A catheter with a small optical fiber or bundle of fibers includes a scanning mechanism constructed with the use of any vibration capable component. Magnetic, piezoelectric or other mechanisms are used to vibrate the end of the fiber and thus create a scanning effect which extends the field of view. This configuration can be used in a catheter with a relatively small diameter. A glass lens or lenses placed in front of the fiber focuses and magnifies the image. A CCD, CMOS, or photodiode camera at the proximal end of the fiber captures the image and transfers it to a computer or processor. A light splitter coupled to a light source provides light through an illumination fiber. The resulting vision catheter is relatively inexpensive and disposable.
    • 具有小光纤或纤维束的导管包括使用任何具有振动能力的部件构成的扫描机构。 使用磁性,压电或其他机构来振动纤维的端部,从而产生延伸视野的扫描效果。 这种构造可以用于具有相对较小直径的导管中。 置于纤维前面的玻璃镜片或镜片聚焦并放大图像。 光纤近端的CCD,CMOS或光电二极管相机捕获图像并将其传输到计算机或处理器。 耦合到光源的光分路器通过照明光纤提供光。 所得到的视觉导管相对便宜并且是一次性的。

    • The technical description relates to perimeters for vehicles. Specific examples relate to vehicle perimeters established by unmanned aerial vehicles (UAVs), such as autonomous drones, for a variety of vehicle types, including manually-driven, partially autonomous, and fully autonomous vehicles. Perimeter devices, vehicles, including autonomous vehicles and human-controlled vehicles, UAVs, and related systems and methods are described. Perimeter devices respond to triggering events, such as vehicle-immobilizing events, GPS-based events, and environment-based events, to establish a perimeter adjacent a vehicle such that observers can visually detect the presence of a signal member, such as a warning triangle having a reflective surface. An example vehicle includes a tractor unit, a trailer connected to the tractor unit, a storage enclosure associated with the tractor unit, and a plurality of perimeter devices disposed in the chamber. Each perimeter device of the plurality of perimeter devices includes a triangular signal member, a base member, and a UAV. Each perimeter device is adapted to deploy from the chamber and establish a perimeter by the vehicle in response to a triggering event, such as parking of the vehicle in a location for which a perimeter must be established, impact of the vehicle with another object, such as during a traffic accident, rollover of the vehicle, or mechanical and/or electrical failure of the vehicle.
