    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 clamp (10) having at least first and second elongate clamping portions (2, 4) adapted to be placed on opposite sides of the hollow anatomical structure (40). The first and second elongate clamping portions (2, 4) respectively include ends coupled together with respective resilient urging members (6, 8) configured to urge at least one of the first and second elongate clamping portions (2, 4) toward the other of the first and second elongate clamping portions (2, 4) from an open position into a clamping position to occlude the hollow anatomical structure (40). The clamp (10) is shaped annularly such that it may surround the hollow anatomical structure (40) in the open position and reorient into a flattened shape in the clamping position to occlude the hollow interior of the hollow anatomical structure (40). Apparatus of the invention further include clamp delivery and actuation devices (80, 200) adapted to deploy the clamp (10).

    摘要: A medical device for localizing a nonpalpable breast lesion. The device includes a tubular introducer needle and a wire guide positioned therein for inserting into a breast to the site of the lesion. The wire guide includes a distal portion having a preformed, resilient helical coil configuration for locking into position about the lesion. The distal portion includes a superelastic metallic alloy for maintaining the helical coil configuration after repeated extensions from and retractions into the needle passageway. The needle is inserted with the wire guide positioned therein into the breast to the site of the lesion and from the distal portion of the needle. The distal end of the needle includes a plurality of indentations for enhancing the ultrasound visualization thereof. As the distal portion of the wire guide emerges from the needle, the acuate distal end of the wire guide cuts into and scribes a helical path about the tissue distal to the lesion. The remainder of the distal portion of the wire guide follows the path scribed by the acuate distal tip and locks about the tissue distal to the lesion. Should the needle and wire guide not be appropriately positioned, the distal portion of the wire guide is retracted into the passageway of the needle to reposition the needle and guide. After desired positioning, the needle is removed with the wire guide remaining in a locked position distally about the lesion for guiding the surgeon to the lesion site during subsequent surgery.
