ABSTRACT:
A stereotaxic catheter includes at least one lumen parallel to an axis thereof. The lumen includes a staff having disposed thereon or therein a predetermined number of spaced-apart markings of a radiopaque material. In a preferred embodiment, the markings are equidistantly spaced circumferential bands of a material having a large X-ray signature. The lumen containing the staff is preferably sealed at both ends and is most preferably sealed in close adjacency to each end of the staff whereby the staff is retained in a stable and predictable positional relationship to the remainder of the catheter.
