    • In one exemplary embodiment, an intraluminal device may include elongated structure formed of a plurality of wires. The intraluminal device may also include a plurality of sets of looped wires longitudinally located at an intermediate area of the elongated structure and the plurality of sets may be spaced circumferentially about the structure and being configured to cooperate with each other to form a plurality of clot entry openings. At least one grouping of woven wires may be longitudinally located adjacent the intermediate area and the at one grouping of woven wires may be configured such that when an opening force is exerted on the elongated structure, the at least one grouping provides structural support to hold open first interstices between the plurality of sets of looped wires.
    • 在一个示例性实施例中,管腔内装置可以包括由多根线形成的细长结构。 腔内装置还可以包括纵向位于细长结构的中间区域处的多组环形线,并且多组可以围绕结构周向间隔开并且被配置为彼此协作以形成多个凝块入口 开口。 至少一组编织线可以纵向地位于中间区域附近,并且一组编织线可以被配置为使得当打开力施加在细长结构上时,该至少一个组提供结构支撑以保持打开 多组环形线之间的第一间隙。

    • A system for guiding placement of a filter within the vasculature of a patient comprises a delivery device having a proximal end and a distal end, a distal portion of the delivery device being configured to receive the filter to be placed. The system further comprises an intravascular ultrasound transducer disposed at the distal end of the delivery device and an interface configured to receive input regarding a surgical procedure including an insertion site and a destination site for placing the filter according to the surgical procedure. The system further comprises a display and a processor that is programmed to: receive input from the interface regarding the surgical procedure, to determine anatomical landmarks between the insertion site and the destination site, to receive an intravascular ultrasound signal from the intravascular ultrasound transducer, to process the intravascular ultrasound signal into an image; and to send the image to the display.
