    • 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,并且当需要标记物递送时允许标记物从孔中流出孔口 。 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。
