    • Apparatus and methods are described, including at least one tool configured to be placed inside a subject's mouth. A first optically-visible marker is coupled to the tool. A second optically-visible marker is coupled to a structure inside the subject's mouth. A plurality of optical cameras are coupled to the tool, and are placed inside the subject's mouth by the tool being placed inside the subject's mouth. The cameras acquire respective images of the inside of the subject's mouth, in which the second optically-visible marker is identifiable. A plurality of optical cameras that are disposed outside the subject's mouth acquire respective images of the tool, while the tool is inside the subject's mouth, in which images the first optically-visible marker is identifiable. Other embodiments are also described.
    • 描述了装置和方法,包括至少一个被配置为放置在受试者的嘴内的工具。 第一光学可见标记与工具耦合。 第二光学可见标记物连接到受试者口腔内的结构。 多个光学摄像机耦合到工具,并且被放置在被检者的嘴内的工具放置在被检者的嘴内。 照相机拍摄被检者口腔内部的各个图像,其中可识别第二光学可见标记物。 设置在被检者的嘴外部的多个光学照相机在工具位于被检者的嘴内时获取工具的各自的图像,其中第一光学可见标记的图像是可识别的。 还描述了其它实施例。

    • An apparatus for use with a biologically-compatible-fluid pressure source, the apparatus includes an elongate carrier, adapted to be inserted through a proximal opening of a body lumen, and a piston head coupled to a distal portion of the carrier. The piston head is adapted to form a pressure seal with a wall of the lumen after the carrier has been inserted into the lumen, and to be advanced distally through the body lumen in response to pressure from the fluid pressure source. The apparatus is configured to facilitate distal advancement of the piston head by facilitating passage of fluid out of the lumen from a site within the lumen distal to the piston head.
    • 一种用于与生物相​​容的流体压力源一起使用的装置,该装置包括一个细长的载体,适于插入通过体腔的近端开口,以及活塞头,其联接到载体的远端部分。 活塞头适于在载体已经插入内腔之后与内腔的壁形成压力密封,并且响应于来自流体压力源的压力而向远侧远端推进通过体腔。 该装置被配置为通过促使流体从内腔远离活塞头的内部位置流出管腔来促进活塞头的远端前进。
