摘要： An obturator with an elongated shaft, a proximal end, a substantially closed distal end and a MRI detectable distal shaft portion, which does not interfere with magnetic resonance imaging of tissue proximate thereto. Preferably, the distal shaft portion has an effective MRI detectable mass so as to provide a clear, T1-weighted image within an outline of the distal shaft portion upon magnetic resonance imaging.

摘要： A marker delivery device is described which has an obturator with an elongated shaft, an inner lumen, a proximal end, and a substantially sealed distal end. One or more tissue markers are deployed within the inner lumen of the elongated shaft of the obturator. Preferably, the tissue marker(s) is disposed within an inner lumen of a marker delivery tube which is disposed within the inner lumen of the elongated shaft of the obturator. The marker delivery tube has an opening for discharging the tissue markers into a body (e.g. biopsy) cavity. The distal tip of the marker delivery tube is configured to penetrate the substantially sealed distal end of the obturator so that tissue markers can be delivered while the obturator is in place within the body. Preferably, the obturator includes a detectable element capable of producing a relatively significant image signature during MRI.
摘要翻译：描述了一种标记输送装置，其具有带有细长轴，内腔，近端和基本上密封的远端的闭塞器。一个或多个组织标记部署在闭塞器的细长轴的内腔内。优选地，组织标记设置在标记输送管的内腔内，该标记物输送管设置在闭塞器的细长轴的内腔内。标记物输送管具有用于将组织标记物排放到体内（例如活检）腔的开口。标记物输送管的远侧末端构造成穿透闭塞器的基本上密封的远端，使得组织标记物可以在闭塞器在体内就位的同时被输送。优选地，闭孔器包括能够在MRI期间产生相对显着的图像特征的可检测元件。
