    • The invention is directed to marker delivery devices and methods of using such devices. The delivery devices embodying features of the invention include a delivery cannula with a discharge opening and a releasable plug disposed in the inner lumen of the delivery cannula so as to at least partially occlude the discharge opening. The releasable plug prevents ingress of tissue, body fluids and the like into the bore of the tube, and prevents the premature discharge of any markers proximal to the releasable plug from passing through the discharge opening before the distal end of the cannula is properly positioned at a desired location within a patient's body. The releasable plug preferably has an MRI detectable element. Preferably, at least one remotely detectable marker mass is provided in the inner lumen of the cannula proximal to the releasable plug.
    • 本发明涉及标记物递送装置和使用这种装置的方法。 体现本发明特征的递送装置包括具有放电开口的输送套管和设置在输送插管的内腔中的可释放插塞,以至少部分地封闭排出口。 可释放的塞子防止组织,体液等进入管的孔中,并且防止任何靠近可释放塞的标记的过早排放通过排出口,在套管的远端被适当地定位在 患者体内所需的位置。 可释放插塞优选具有MRI可检测元件。 优选地,至少一个可远程检测的标记物质在靠近可释放塞的插管的内腔中提供。

    • The invention provides marker delivery devices, assemblies, and methods. Assemblies embodying features of the invention include marker delivery devices having a delivery tube with an orifice, markers, and a plug releasably disposed in the tube occluding the orifice. The plug prevents markers from passing through the orifice before the marker is to be placed at a desired location within a patient's body, prevents ingress of tissue into the bore of the tube, and allows markers to pass out of the orifice when marker delivery is desired. Guidance of a delivery tube to a desired location within a patient's body may include the use of an imaging device, with or without the use of a guide cannula. The plug may itself serve as a marker, and may be the sole marker. Markers may be detectable by ultrasound, X-ray, magnetic resonance imaging, and other imaging devices, and may include bioactive elements.
    • 本发明提供标记递送装置,组件和方法。 体现本发明特征的组件包括具有输送管的标记输送装置,该输送管具有孔口,标记物和可释放地设置在阻塞孔口的管中的塞子。 在将标记物放置在患者体内的期望位置之前,塞子防止标记物通过孔口,防止组织进入管孔中,并且当需要标记递送时允许标记物从孔口中流出孔口 。 将输送管引导到患者体内的期望位置可以包括在使用或不使用引导套管的情况下使用成像装置。 插头本身可以用作标记,并且可以是唯一的标记。 标记可以通过超声,X射线,磁共振成像和其他成像装置检测,并且可以包括生物活性元件。
