Abstract
A venous access port assembly (10) having a housing base (28) with a discharge port (16), a septum (14) and a cap (48), with an interior reservoir (22). The housing base (28) is provided with X-ray discernable indicia (100,200) to identify an attribute of the assembly (10) 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 (102) through a disc of radiopaque material (100) where the cutouts are in the form of alphabetical letters such as “CT”, or can be a set (200) of discrete elements (202) of radiopaque material, that are affixed along the bottom surface of the housing base or embedded within the thickness of the bottom housing wall.
