A radiopaque marking system for a device meant to be inserted into a body, such as a medical device inserted into a human body, and imaged with an x-ray source includes a tube having a distal end and an outer periphery which can be divided into four quadrants. A first radiopaque marker section is located only in a first quadrant of the body adjacent the distal end thereof. A second radiopaque marker section is located only in a second quadrant of the body adjacent the distal end portion. If desired, the two marker sections can contact each other along at least one corner of the two sections.
