    摘要： An emboli filter for deployment in a body lumen to capture emboli entrained in a fluid flowing through the lumen includes a flexible elongated member sized to be passed through the lumen. A filter media is carried on and substantially surrounding the elongated member. The filter media has a first end secured to the elongated member adjacent the distal end. A second end of the filter media has a periphery movable toward and away from the elongated member. Opposing internal surfaces of the filter media define a volume into which emboli may flow through the second end when the periphery is moved away from the elongated member. The emboli are trapped within the volume when the periphery is moved toward the elongated member. An actuator moves the periphery toward and way from the elongated member. The actuator includes a plurality of elastic loops. The loops are biased to an open loop configuration with the loops urging the periphery away from the elongated member. The actuator is adapted to be manipulated by an operator to urge the loops against the bias to a closed position permitting movement of the periphery toward the elongated member without interference from the loops.

    摘要翻译： 用于部署在体腔中的栓塞过滤器以捕获夹带在流过管腔的流体中的栓塞，包括尺寸适于通过内腔的柔性细长构件。 过滤介质被承载并且基本上围绕细长构件。 过滤介质的第一端固定在与远端相邻的细长构件上。 过滤介质的第二端具有朝向和远离细长构件移动的周边。 过滤介质的相对的内表面限定了一个体积，当周边移动离开细长构件时，栓塞可以流经第二端。 当周边朝向细长构件移动时，栓塞被捕获在体积内。 致动器使周边朝向和远离细长构件移动。 致动器包括多个弹性环。 这些环被偏压到开环构型，其中环使得周边远离细长构件。 致动器适于由操作者操纵以将回路抵抗偏压推动到关闭位置，允许周边朝向细长构件移动而不受到环的干扰。

    摘要： A ductal access device is provided for accessing a breast duct and collecting biological material from within the duct. The access device may include an elongated member having an outer diameter sized for positioning within the breast duct and an internal lumen for infusing a fluid into the breast duct and collecting fluid from the breast duct. The elongated member may include a central axis extending through the internal lumen and a different axis being parallel to the central axis defining an off-axis configuration. An elongated distal tip extends beyond the distal end of the internal lumen and along the different axis. The elongated distal tip has a closed distal end for navigating within the breast duct. The elongated distal tip may include an internal passageway that is sized to slidiably or removably receive an elongated introducer.
