Abstract
A venous access port assembly having a housing base with a discharge port, a septum, and a cap, with an interior reservoir. The housing base is provided with X-ray discernable indicia to identify an attribute of the assembly after its implantation and clearly appear on an X-ray of the patient in a manner informing the radiologist or technologist and the medical practitioner of that particular attribute. Such indicia can be depicted as cutouts through a disc of radiopaque material where the cutouts are in the form of alphabetical letters such as “CT”, or can be a set of discrete elements of radiopaque material, that are affixed along the bottom surface of the housing base or embedded within the thickness of the bottom housing wall.
