摘要：
An elongate member for inserting into a cannula is disclosed. The cannula comprises an electrically insulated region and an electrically exposed conductive region for delivering energy to form a lesion within a patients body at an intended location relative to the electrically exposed conductive region. The elongate member is structured to cooperatively engage with the cannula at a pre-determined insertion depth and to provide a variation in radiopacity, at a pre-determined position relative to the electrically exposed conductive region, when inserted to the pre-determined insertion depth. The variation in radiopacity provides a visual reference for distinguishing, using fluoroscopic imaging, the intended location of the lesion.
