To avoid exposing medical personnel to frequent radiation during patient treatment, a radiopaque indicator is used to locate catheters or similar subcutaneous ports and devices. An attached extension rod allows the medical personnel to remain farther outside a fluoroscope's radiated area, but still manipulate the indicator. Because it is radiopaque, personnel can see its position relative to a patient's extra corporal port on a fluoroscope, fix the position precisely, make the puncture and adjustment and then address the patient's medical needs after completing the barium swallow or other medical treatment.
