Abstract
An implantable portal includes a septum that has embedded therein a plurality of formations that together form an indicia adapted to identify at least one characteristic of the portal. The formations are configured from impressions formed on different layers of the septum spatially separated along the vertical axis of the septum. The impressions are filled with a radiopaque material. The superposed formations do not overlap when viewed from atop the septum. When viewed under radiographic imaging from the top of the septum, a 3-D identification indicia is presented to the viewer. The 3-D indicia may be used as a 3-D marker to focus the location of the septum where a needle to access the fluid reservoir of the portal may be inserted.
