    • Apparatus, methods, and kits, are provided for use in combination with a conventional bronchoscope or other lung viewing scope. In particular, sheaths having an inflatable cuff at their distal end are provided to receive a viewing scope through a lumen thereof. The sheaths thus provide an inflatable cuff on a viewing scope assembly so that the scope can be used in procedures which require selective isolation of regions of a patient's lungs. In particular embodiments, the sheaths may include stop elements for properly positioning a viewing scope therein, pressure transducers for providing accurate lung pressure information during procedures, and the like. Methods for using and forming sheaths having inflatable cuffs are also described.
    • 设备,方法和试剂盒被提供用于与常规支气管镜或其它肺观察范围组合使用。 特别地,具有在其远端具有可充气袖带的护套被提供以通过其内腔接收观察范围。 护套因此在观察镜组件上提供可充气的袖带,使得镜片可以在需要选择性隔离患者肺部区域的过程中使用。 在具体实施例中,护套可以包括用于在其中适当地定位观察范围的止动元件,用于在程序期间提供准确的肺压信息的压力传感器等。 还描述了使用和形成具有可充气袖口的护套的方法。

    • The disclosed lubricating suppository is formulated to have properties advantageous for coital use, including extraordinary water washability. The ingredients and phase relationships of the suppository composition provide a high degree of compatibility with water and with naturally-occurring vaginal moisture. The suppository composition contains a glyceride lubricant and can be lubricious with or without the presence of moisture. The suppository, which is solid at room temperature but melts in a short time at body temperature, is made by dissolving, for example, 10-30 parts by weight of high-HLB (e.g. >14) nonionic surfactant in 50-70 parts by weight of a molten, water-soluble polyoxyethylene glycol component and by dispersing or emulsifying 10-20 parts by weight of the glyceride (e.g. a triglyceride of C.sub.6 -C.sub.18 aliphatic carboxylic acids) included in the composition. In use, the suppository can be inserted prior to coitus and permitted to melt to a liquid, which is lubricious even in the absence of moisture, but still has the aforementioned extraordinary water washability.
    • 公开的润滑栓剂被配制成具有有利于配偶使用的性质,包括非凡的水洗性。 栓剂组合物的成分和相位关系提供与水和天然存在的阴道水分的高度相容性。 栓剂组合物含有甘油酯润滑剂,并且可以在有或没有水分的情况下润滑。 在室温下固体但在体温短时间熔化的栓剂是通过将例如10-30重量份的高HLB(例如> 14)非离子表面活性剂溶解在50-70份中制成的栓剂 熔融的水溶性聚氧乙烯二醇组分的重量,并通过分散或乳化10-20重量份包含在组合物中的甘油酯(例如C 6 -C 18脂族羧酸的甘油三酯)。 在使用中,栓剂可以在交联之前插入并允许熔化成液体,即使在没有水分的情况下也是润滑的,但仍然具有上述非凡的水洗性。

    • In some embodiments, a tissue removal system may comprise a handheld housing and a tissue collection chamber coupled to a distal portion of the handheld housing and comprising a cylindrical portion, a motor, and an articulation mechanism. The articulation mechanism may comprise a shaft comprising an outer tubular member and an inner tubular member disposed within the outer tubular member and coupled to the cylindrical portion of the tissue collection chamber, a drum component slidably engaged with the cylindrical portion of the tissue collection chamber and coupled to the outer tubular member, an articulation drive component rotatably coupled to the drum component and to the cylindrical portion of the tissue collection chamber, and a tissue removal assembly coupled to the shaft and operable by the motor. The shaft may be articulated by rotating the articulation drive component and causing the drum component to translate in a proximal direction.
    • 在一些实施例中,组织去除系统可以包括手持式外壳和联接到手持式外壳的远端部分的组织收集腔,并且包括圆柱形部分,马达和关节运动机构。 所述关节运动机构可以包括轴,所述轴包括外部管状构件和设置在所述外部管状构件内并联接到所述组织收集室的圆柱形部分的内部管状构件,与所述组织收集室的圆柱形部分可滑动地接合的鼓构件, 联接到外部管状构件,可旋转地联接到鼓部件和组织收集室的圆柱形部分的关节运动驱动部件,以及联接到轴并且可由电动机操作的组织移除组件。 轴可以通过旋转关节运动部件并使滚筒部件沿近端方向平移而铰接。
