    • A locating guide (150) for locating a target tissue site within a patient includes a body (122), a first substantially radiopaque reference marker (124A-B, 126A-B, 128,130) on the body, and a second substantially radiopaque reference marker (154, 156) extending from a major surface of the body. The reference markers provide reference points that extend in at least two dimensions, and may be useful for registering a medical image of tissue with an actual location on or within the patient in order to more accurately and precisely locate a target tissue site within the patient. In some embodiments, the second reference marker is oriented at a predetermined angle relative to the major surface of the body, and provides a guide that a clinician may reference in order to orient a medical- element introducer (152) when introducing the introducer into the patient to access a particular target tissue site.
    • 用于定位患者内的目标组织部位的定位引导件(150)包括主体(122),身体上的第一基本上不透射线的参考标记(124A-B,126A-B,128,130)和第二基本上不透射线的参考标记 (154,156)从主体的主表面延伸。 参考标记提供在至少两个维度上延伸的参考点,并且可用于将具有实际位置的组织的医学图像登记在患者身上或内部,以便更精确地和精确地定位患者内的目标组织部位。 在一些实施例中,第二参考标记物相对于主体的主表面以预定角度定向,并且提供临床医生可引用的引导件,以便在将导引器引入到引导器时定向医疗元件引导器(152) 患者进入特定的目标组织部位。
