Abstract
A venous access port assembly having a housing base with a discharge stem, a cap, and an interior reservoir. The port assembly 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. The indicia are cuts in a reservoir lining of radiopaque material such as metal where the cuts having narrow slot width are in the form of one or more sets of alphabetical letters such as “CT” in the lining's side wall or bottom wall.
