摘要

A venous access port assembly having a housing base with a discharge stem, a septum, 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.
