    • An apparatus is disclosed suitable for electrostatic spraying from fixed wing aircraft. The apparatus includes a linear electrostatic spraying nozzle 2 and electrodes 4 placed near the nozzle's spraying edge to intensify the electric field strength at the spraying edge sufficiently to produce ligaments of the liquid to be sprayed from the spraying edge. In order that the airstream due to the aircraft's movement does not destroy the ligamets, the sprayhead and the electrodes are positioned so that part of the airstream flows between them. The spray head and the electrodes are so shaped and positioned that when directed to spray in substantially the same direction as the airstream, a turbulence free wake is left in the region of the ligaments.

    • Catheter including an inner tubular member having a fluid lumen defined therein and an exterior surface. The exterior surface defining a first distal flow port and a second distal flow port. An outer tubular member is movable relative to the inner tubular member in a proximal direction and having an interior surface. A first pressure chamber is defined between the exterior surface and the interior surface, and between a first distal seal assembly and a first proximal seal assembly. A second pressure chamber is defined between the exterior surface and the interior surface, and between a second distal seal assembly and a second proximal seal assembly. Fluid introduced through the fluid lumen pressurizes the first pressure chamber and the second pressure chamber to generate a respective force at the first proximal seal assembly and to the second proximal seal assembly to urge the outer tubular member in the proximal direction.
    • 导管包括具有限定在其中的流体腔的内部管状构件和外部表面。 所述外表面限定第一远端流动端口和第二远端流动端口。 外部管状构件可以在近端方向上相对于内部管状构件移动并且具有内部表面。 第一压力室被限定在外表面和内表面之间以及在第一远端密封组件和第一近端密封组件之间。 第二压力室限定在外表面和内表面之间以及在第二远端密封组件和第二近端密封组件之间。 通过流体腔引入的流体对第一压力室和第二压力室加压,以在第一近侧密封组件和第二近端密封组件处产生相应的力,以沿近侧方向推动外部管状构件。
