摘要：
Apparatus for delivering brachytherapy to a target tissue region includes anelongate body including a proximal end, a distal end sized for introductioninto a tissue tract and carrying a plurality of elongate members includingpathways for receiving a source of radiation. The elongate members are movablebetween collapsed and expanded configurations. During use, a tract is createdthrough tissue, and the elongate body carrying the elongate members isadvanced through the tract into a target location with the elongate members inthe collapsed configuration. The elongate members arc directed to the expandedconfiguration at the target location, and radiation is delivered to treattissue at the target location, e.g., by introducing one or more radiationsources along the pathways.
